- be put into non-blocking mode (and vice versa) using the F_SETFL command
- of the fcntl system call. This is a standard system call, documented in the Linux
- manual page for fcntl. Only one user can open the Audio Device in O_RDWR

- code will be returned. If the Audio Device is opened in O_RDONLY mode, the
- only ioctl call that can be used is AUDIO_GET_STATUS. All other call will

-<para>When an open() call has succeeded, the device will be ready for use.
- The significance of blocking or non-blocking mode is described in the

- be put into non-blocking mode (and vice versa) using the F_SETFL command
- of the fcntl system call. This is a standard system call, documented in the Linux

-<title>DVB Frontend properties</title>
-<para>Tuning into a Digital TV physical channel and starting decoding it
- requires changing a set of parameters, in order to control the
- tuner, the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
- antenna subsystem via Satellite Equipment Control (SEC), on satellite
- systems. The actual parameters are specific to each particular digital
- TV standards, and may change as the digital TV specs evolves.</para>
-<para>In the past, the strategy used was to have a union with the parameters
- needed to tune for DVB-S, DVB-C, DVB-T and ATSC delivery systems grouped
- there. The problem is that, as the second generation standards appeared,
- those structs were not big enough to contain the additional parameters.
- Also, the union didn't have any space left to be expanded without breaking
- userspace. So, the decision was to deprecate the legacy union/struct based
- approach, in favor of a properties set approach.</para>
-
-<para>NOTE: on Linux DVB API version 3, setting a frontend were done via
- <link linkend="dvb-frontend-parameters">struct <constant>dvb_frontend_parameters</constant></link>.
- This got replaced on version 5 (also called "S2API", as this API were
- added originally_enabled to provide support for DVB-S2), because the old
- API has a very limited support to new standards and new hardware. This
- section describes the new and recommended way to set the frontend, with
- suppports all digital TV delivery systems.</para>
-
-<para>Example: with the properties based approach, in order to set the tuner
- to a DVB-C channel at 651 kHz, modulated with 256-QAM, FEC 3/4 and symbol
- rate of 5.217 Mbauds, those properties should be sent to

-<para>The kind of parameters passed to the frontend device for tuning depend on
-the kind of hardware you are using.</para>
-<para>The struct <constant>dvb_frontend_parameters</constant> uses an
-union with specific per-system parameters. However, as newer delivery systems
-required more data, the structure size weren't enough to fit, and just
-extending its size would break the existing applications. So, those parameters
-were replaced by the usage of <link linkend="FE_GET_PROPERTY">
-<constant>FE_GET_PROPERTY/FE_SET_PROPERTY</constant></link> ioctl's. The
-new API is flexible enough to add new parameters to existing delivery systems,
-and to add newer delivery systems.</para>
-<para>So, newer applications should use <link linkend="FE_GET_PROPERTY">
-<constant>FE_GET_PROPERTY/FE_SET_PROPERTY</constant></link> instead, in
-order to be able to support the newer System Delivery like DVB-S2, DVB-T2,
-DVB-C2, ISDB, etc.</para>
-<para>All kinds of parameters are combined as an union in the FrontendParameters structure:

- struct dvb_vsb_parameters vsb;
- } u;
-};
-</programlisting></para>
-<para>In the case of QPSK frontends the <constant>frequency</constant> field specifies the intermediate
-frequency, i.e. the offset which is effectively added to the local oscillator frequency (LOF) of
-the LNB. The intermediate frequency has to be specified in units of kHz. For QAM and
-OFDM frontends the <constant>frequency</constant> specifies the absolute frequency and is given in Hz.

-
-<para>The first API for DVB cards we used at Convergence in late 1999
-was an extension of the Video4Linux API which was primarily developed
-for frame grabber cards. As such it was not really well suited to be
-used for DVB cards and their new features like recording MPEG streams
-and filtering several section and PES data streams at the same time.
-</para>
-
-<para>In early 2000, we were approached by Nokia with a proposal for a
-new standard Linux DVB API. As a commitment to the development of
-terminals based on open standards, Nokia and Convergence made it
-available to all Linux developers and published it on
-<ulink url="https://linuxtv.org" /> in September 2000.
-Convergence is the maintainer of the Linux DVB API. Together with the
-LinuxTV community (i.e. you, the reader of this document), the Linux DVB
-API will be constantly reviewed and improved. With the Linux driver for
-the Siemens/Hauppauge DVB PCI card Convergence provides a first
-implementation of the Linux DVB API.</para>

-<para>This system call opens a named video device (e.g. /dev/dvb/adapter0/video0)
- for subsequent use.</para>
-<para>When an open() call has succeeded, the device will be ready for use.
- The significance of blocking or non-blocking mode is described in the
- documentation for functions where there is a difference. It does not affect the
- semantics of the open() call itself. A device opened in blocking mode can later
- be put into non-blocking mode (and vice versa) using the F_SETFL command
- of the fcntl system call. This is a standard system call, documented in the Linux
- manual page for fcntl. Only one user can open the Video Device in O_RDWR
- mode. All other attempts to open the device in this mode will fail, and an
- error-code will be returned. If the Video Device is opened in O_RDONLY
- mode, the only ioctl call that can be used is VIDEO_GET_STATUS. All other
- call will return an error code.</para>

- not available, the behavior depends on whether the device is in blocking or
- non-blocking mode. In the latter case, the call fails immediately with errno
- set to EWOULDBLOCK. In the former case, the call blocks until an event
- becomes available. The standard Linux poll() and/or select() system calls can
- be used with the device file descriptor to watch for new events. For select(),
- the file descriptor should be included in the exceptfds argument, and for
- poll(), POLLPRI should be specified as the wake-up condition. Read-only
- permissions are sufficient for this ioctl call.</para>

-
- <section id="cec-intro">
- <title>Introduction</title>
- <para>
- Note: this documents the proposed CEC API. This API is not yet finalized and
- is currently only available as a staging kernel module.
- </para>
- <para>HDMI connectors provide a single pin for use by the Consumer Electronics
- Control protocol. This protocol allows different devices connected by an HDMI cable
- to communicate. The protocol for CEC version 1.4 is defined in supplements 1 (CEC)
- and 2 (HEAC or HDMI Ethernet and Audio Return Channel) of the HDMI 1.4a
- (<xref linkend="hdmi" />) specification and the extensions added to CEC version 2.0
- are defined in chapter 11 of the HDMI 2.0 (<xref linkend="hdmi2" />) specification.
- </para>
-
- <para>The bitrate is very slow (effectively no more than 36 bytes per second) and
- is based on the ancient AV.link protocol used in old SCART connectors. The protocol
- closely resembles a crazy Rube Goldberg contraption and is an unholy mix of low and
- high level messages. Some messages, especially those part of the HEAC protocol layered
- on top of CEC, need to be handled by the kernel, others can be handled either by the
- kernel or by userspace.</para>
-
- <para>In addition, CEC can be implemented in HDMI receivers, transmitters and in USB
- devices that have an HDMI input and an HDMI output and that control just the CEC pin.</para>
-
- <para>Drivers that support CEC will create a CEC device node (/dev/cecX)
- to give userspace access to the CEC adapter. The &CEC-ADAP-G-CAPS; ioctl will tell userspace
- what it is allowed to do.</para>

- </para>
-
- <para>By default any filehandle can use &CEC-TRANSMIT; and &CEC-RECEIVE;, but
-in order to prevent applications from stepping on each others toes it must be possible
-to obtain exclusive access to the CEC adapter. This ioctl sets the filehandle
-to initiator and/or follower mode which can be exclusive depending on the chosen
-mode. The initiator is the filehandle that is used
-to initiate messages, i.e. it commands other CEC devices. The follower is the filehandle
-that receives messages sent to the CEC adapter and processes them. The same filehandle
-can be both initiator and follower, or this role can be taken by two different
-filehandles.</para>
-
- <para>When a CEC message is received, then the CEC framework will decide how
-it will be processed. If the message is a reply to an earlier transmitted message,
-then the reply is sent back to the filehandle that is waiting for it. In addition
-the CEC framework will process it.</para>
-
- <para>If the message is not a reply, then the CEC framework will process it
-first. If there is no follower, then the message is just discarded and a feature
-abort is sent back to the initiator if the framework couldn't process it. If there
-is a follower, then the message is passed on to the follower who will use
-&CEC-RECEIVE; to dequeue the new message. The framework expects the follower to
-make the right decisions.</para>
-
- <para>The CEC framework will process core messages unless requested otherwise
-by the follower. The follower can enable the passthrough mode. In that case, the
-CEC framework will pass on most core messages without processing them and
-the follower will have to implement those messages. There are some messages
-that the core will always process, regardless of the passthrough mode. See
-<xref linkend="cec-core-processing" /> for details.</para>
-
- <para>If there is no initiator, then any CEC filehandle can use &CEC-TRANSMIT;.
-If there is an exclusive initiator then only that initiator can call &CEC-TRANSMIT;.
-The follower can of course always call &CEC-TRANSMIT;.</para>

-
- <para>In practice most steps are optional and can be executed out of
-order. It depends on the V4L2 device type, you can read about the
-details in <xref linkend="devices" />. In this chapter we will discuss
-the basic concepts applicable to all devices.</para>
-
- <section id="open">
- <title>Opening and Closing Devices</title>
-
- <section>
- <title>Device Naming</title>
-
- <para>V4L2 drivers are implemented as kernel modules, loaded
-manually by the system administrator or automatically when a device is
-first discovered. The driver modules plug into the "videodev" kernel
-module. It provides helper functions and a common application
-interface specified in this document.</para>
-
- <para>Each driver thus loaded registers one or more device nodes
-with major number 81 and a minor number between 0 and 255. Minor numbers
-are allocated dynamically unless the kernel is compiled with the kernel
-option CONFIG_VIDEO_FIXED_MINOR_RANGES. In that case minor numbers are
-allocated in ranges depending on the device node type (video, radio, etc.).</para>
-
- <para>Many drivers support "video_nr", "radio_nr" or "vbi_nr"
-module options to select specific video/radio/vbi node numbers. This allows
-the user to request that the device node is named e.g. /dev/video5 instead
-of leaving it to chance. When the driver supports multiple devices of the same
-type more than one device node number can be assigned, separated by commas:
- <informalexample>
- <screen>
-&gt; modprobe mydriver video_nr=0,1 radio_nr=0,1</screen>
- </informalexample></para>
-
- <para>In <filename>/etc/modules.conf</filename> this may be
-written as: <informalexample>
- <screen>
-options mydriver video_nr=0,1 radio_nr=0,1
- </screen>
- </informalexample> When no device node number is given as module
-option the driver supplies a default.</para>
-
- <para>Normally udev will create the device nodes in /dev automatically
-for you. If udev is not installed, then you need to enable the
-CONFIG_VIDEO_FIXED_MINOR_RANGES kernel option in order to be able to correctly
-relate a minor number to a device node number. I.e., you need to be certain
-that minor number 5 maps to device node name video5. With this kernel option
-different device types have different minor number ranges. These ranges are
-listed in <xref linkend="devices" />.
-</para>
-
- <para>The creation of character special files (with
-<application>mknod</application>) is a privileged operation and
-devices cannot be opened by major and minor number. That means
-applications cannot <emphasis>reliable</emphasis> scan for loaded or
-installed drivers. The user must enter a device name, or the
-application can try the conventional device names.</para>
- </section>
-
- <section id="related">
- <title>Related Devices</title>
-
- <para>Devices can support several functions. For example
-video capturing, VBI capturing and radio support.</para>
-
- <para>The V4L2 API creates different nodes for each of these functions.</para>
-
- <para>The V4L2 API was designed with the idea that one device node could support
-all functions. However, in practice this never worked: this 'feature'
-was never used by applications and many drivers did not support it and if
-they did it was certainly never tested. In addition, switching a device
-node between different functions only works when using the streaming I/O
-API, not with the read()/write() API.</para>
-
- <para>Today each device node supports just one function.</para>
-
- <para>Besides video input or output the hardware may also
-support audio sampling or playback. If so, these functions are
-implemented as ALSA PCM devices with optional ALSA audio mixer
-devices.</para>
-
- <para>One problem with all these devices is that the V4L2 API
-makes no provisions to find these related devices. Some really
-complex devices use the Media Controller (see <xref linkend="media_controller" />)
-which can be used for this purpose. But most drivers do not use it,
-and while some code exists that uses sysfs to discover related devices
-(see libmedia_dev in the <ulink url="http://git.linuxtv.org/cgit.cgi/v4l-utils.git/">v4l-utils</ulink>
-git repository), there is no library yet that can provide a single API towards
-both Media Controller-based devices and devices that do not use the Media Controller.
-If you want to work on this please write to the linux-media mailing list: &v4l-ml;.</para>
- </section>
-
- <section>
- <title>Multiple Opens</title>
-
- <para>V4L2 devices can be opened more than once.<footnote><para>
-There are still some old and obscure drivers that have not been updated to
-allow for multiple opens. This implies that for such drivers &func-open; can
-return an &EBUSY; when the device is already in use.</para></footnote>
-When this is supported by the driver, users can for example start a
-"panel" application to change controls like brightness or audio
-volume, while another application captures video and audio. In other words, panel
-applications are comparable to an ALSA audio mixer application.
-Just opening a V4L2 device should not change the state of the device.<footnote>
-<para>Unfortunately, opening a radio device often switches the state of the
-device to radio mode in many drivers. This behavior should be fixed eventually
-as it violates the V4L2 specification.</para></footnote></para>
-
- <para>Once an application has allocated the memory buffers needed for
-streaming data (by calling the &VIDIOC-REQBUFS; or &VIDIOC-CREATE-BUFS; ioctls,
-or implicitly by calling the &func-read; or &func-write; functions) that
-application (filehandle) becomes the owner of the device. It is no longer
-allowed to make changes that would affect the buffer sizes (e.g. by calling
-the &VIDIOC-S-FMT; ioctl) and other applications are no longer allowed to allocate
-buffers or start or stop streaming. The &EBUSY; will be returned instead.</para>
-
- <para>Merely opening a V4L2 device does not grant exclusive
-access.<footnote>
- <para>Drivers could recognize the
-<constant>O_EXCL</constant> open flag. Presently this is not required,
-so applications cannot know if it really works.</para>
- </footnote> Initiating data exchange however assigns the right
-to read or write the requested type of data, and to change related
-properties, to this file descriptor. Applications can request
-additional access privileges using the priority mechanism described in
-<xref linkend="app-pri" />.</para>
- </section>
-
- <section>
- <title>Shared Data Streams</title>
-
- <para>V4L2 drivers should not support multiple applications
-reading or writing the same data stream on a device by copying
-buffers, time multiplexing or similar means. This is better handled by
-a proxy application in user space.</para>
- </section>
-
- <section>
- <title>Functions</title>
-
- <para>To open and close V4L2 devices applications use the
-&func-open; and &func-close; function, respectively. Devices are
-programmed using the &func-ioctl; function as explained in the
-following sections.</para>
- </section>
- </section>
-
- <section id="querycap">
- <title>Querying Capabilities</title>
-
- <para>Because V4L2 covers a wide variety of devices not all
-aspects of the API are equally applicable to all types of devices.
-Furthermore devices of the same type have different capabilities and
-this specification permits the omission of a few complicated and less
-important parts of the API.</para>
-
- <para>The &VIDIOC-QUERYCAP; ioctl is available to check if the kernel
-device is compatible with this specification, and to query the <link
-linkend="devices">functions</link> and <link linkend="io">I/O
-methods</link> supported by the device.</para>
-
- <para>Starting with kernel version 3.1, VIDIOC-QUERYCAP will return the
-V4L2 API version used by the driver, with generally matches the Kernel version.
-There's no need of using &VIDIOC-QUERYCAP; to check if a specific ioctl is
-supported, the V4L2 core now returns ENOTTY if a driver doesn't provide
-support for an ioctl.</para>
-
- <para>Other features can be queried
-by calling the respective ioctl, for example &VIDIOC-ENUMINPUT;
-to learn about the number, types and names of video connectors on the
-device. Although abstraction is a major objective of this API, the
-&VIDIOC-QUERYCAP; ioctl also allows driver specific applications to reliably identify
-the driver.</para>
-
- <para>All V4L2 drivers must support
-<constant>VIDIOC_QUERYCAP</constant>. Applications should always call
-this ioctl after opening the device.</para>
- </section>
-
- <section id="app-pri">
- <title>Application Priority</title>
-
- <para>When multiple applications share a device it may be
-desirable to assign them different priorities. Contrary to the
-traditional "rm -rf /" school of thought a video recording application
-could for example block other applications from changing video
-controls or switching the current TV channel. Another objective is to
-permit low priority applications working in background, which can be
-preempted by user controlled applications and automatically regain
-control of the device at a later time.</para>
-
- <para>Since these features cannot be implemented entirely in user
-space V4L2 defines the &VIDIOC-G-PRIORITY; and &VIDIOC-S-PRIORITY;
-ioctls to request and query the access priority associate with a file
-descriptor. Opening a device assigns a medium priority, compatible
-with earlier versions of V4L2 and drivers not supporting these ioctls.
-Applications requiring a different priority will usually call
-<constant>VIDIOC_S_PRIORITY</constant> after verifying the device with
-the &VIDIOC-QUERYCAP; ioctl.</para>
-
- <para>Ioctls changing driver properties, such as &VIDIOC-S-INPUT;,
-return an &EBUSY; after another application obtained higher priority.</para>
- </section>
-
- <section id="video">
- <title>Video Inputs and Outputs</title>
-
- <para>Video inputs and outputs are physical connectors of a
-device. These can be for example RF connectors (antenna/cable), CVBS
-a.k.a. Composite Video, S-Video or RGB connectors. Video and VBI
-capture devices have inputs. Video and VBI output devices have outputs,
-at least one each. Radio devices have no video inputs or outputs.</para>
-
- <para>To learn about the number and attributes of the
-available inputs and outputs applications can enumerate them with the
-&VIDIOC-ENUMINPUT; and &VIDIOC-ENUMOUTPUT; ioctl, respectively. The
-&v4l2-input; returned by the <constant>VIDIOC_ENUMINPUT</constant>
-ioctl also contains signal status information applicable when the
-current video input is queried.</para>
-
- <para>The &VIDIOC-G-INPUT; and &VIDIOC-G-OUTPUT; ioctls return the
-index of the current video input or output. To select a different
-input or output applications call the &VIDIOC-S-INPUT; and
-&VIDIOC-S-OUTPUT; ioctls. Drivers must implement all the input ioctls
-when the device has one or more inputs, all the output ioctls when the
-device has one or more outputs.</para>

- <title>Audio Inputs and Outputs</title>
-
- <para>Audio inputs and outputs are physical connectors of a
-device. Video capture devices have inputs, output devices have
-outputs, zero or more each. Radio devices have no audio inputs or
-outputs. They have exactly one tuner which in fact
-<emphasis>is</emphasis> an audio source, but this API associates
-tuners with video inputs or outputs only, and radio devices have
-none of these.<footnote>
- <para>Actually &v4l2-audio; ought to have a
-<structfield>tuner</structfield> field like &v4l2-input;, not only
-making the API more consistent but also permitting radio devices with
-multiple tuners.</para>
- </footnote> A connector on a TV card to loop back the received
-audio signal to a sound card is not considered an audio output.</para>
-
- <para>Audio and video inputs and outputs are associated. Selecting
-a video source also selects an audio source. This is most evident when
-the video and audio source is a tuner. Further audio connectors can
-combine with more than one video input or output. Assumed two
-composite video inputs and two audio inputs exist, there may be up to
-four valid combinations. The relation of video and audio connectors
-is defined in the <structfield>audioset</structfield> field of the
-respective &v4l2-input; or &v4l2-output;, where each bit represents
-the index number, starting at zero, of one audio input or output.</para>
-

-as <constant>VIDIOC_ENUMAUDIO</constant> and
-<constant>VIDIOC_ENUMAUDOUT</constant> do, not just an index.</para>
-
- <para>To select an audio input and change its properties
-applications call the &VIDIOC-S-AUDIO; ioctl. To select an audio
-output (which presently has no changeable properties) applications
-call the &VIDIOC-S-AUDOUT; ioctl.</para>
-
- <para>Drivers must implement all audio input ioctls when the device
-has multiple selectable audio inputs, all audio output ioctls when the

-
- <para>A video or radio device cannot support both a tuner and a

-is for a tuner or a modulator.</para>

-particular standard, although presenting the user a menu of supported
-standards is preferred. To enumerate and query the attributes of the

-
- <para>Many of the defined standards are actually just variations

- The video standards discussed so far have been dealing with Analog TV and the

-video signals and there is a need to extend the API to select the video timings
-for these interfaces. Since it is not possible to extend the &v4l2-std-id; due to
-the limited bits available, a new set of ioctls was added to set/get video timings at
-the input and output.</para>
-
- <para>These ioctls deal with the detailed digital video timings that define
-each video format. This includes parameters such as the active video width and height,
-signal polarities, frontporches, backporches, sync widths etc. The <filename>linux/v4l2-dv-timings.h</filename>
-header can be used to get the timings of the formats in the <xref linkend="cea861" /> and
-<xref linkend="vesadmt" /> standards.
- </para>
-
- <para>To enumerate and query the attributes of the DV timings supported by a device

- To set DV timings for the device applications use the

- <title>Data Format Negotiation</title>
-
- <para>Different devices exchange different kinds of data with
-applications, for example video images, raw or sliced VBI data, RDS
-datagrams. Even within one kind many different formats are possible,
-in particular an abundance of image formats. Although drivers must
-provide a default and the selection persists across closing and
-reopening a device, applications should always negotiate a data format
-before engaging in data exchange. Negotiation means the application
-asks for a particular format and the driver selects and reports the
-best the hardware can do to satisfy the request. Of course
-applications can also just query the current selection.</para>
-
- <para>A single mechanism exists to negotiate all data formats
-using the aggregate &v4l2-format; and the &VIDIOC-G-FMT; and
-&VIDIOC-S-FMT; ioctls. Additionally the &VIDIOC-TRY-FMT; ioctl can be
-used to examine what the hardware <emphasis>could</emphasis> do,
-without actually selecting a new data format. The data formats
-supported by the V4L2 API are covered in the respective device section
-in <xref linkend="devices" />. For a closer look at image formats see
-<xref linkend="pixfmt" />.</para>
-
- <para>The <constant>VIDIOC_S_FMT</constant> ioctl is a major
-turning-point in the initialization sequence. Prior to this point
-multiple panel applications can access the same device concurrently to
-select the current input, change controls or modify other properties.
-The first <constant>VIDIOC_S_FMT</constant> assigns a logical stream
-(video data, VBI data etc.) exclusively to one file descriptor.</para>
-
- <para>Exclusive means no other application, more precisely no
-other file descriptor, can grab this stream or change device
-properties inconsistent with the negotiated parameters. A video
-standard change for example, when the new standard uses a different
-number of scan lines, can invalidate the selected image format.
-Therefore only the file descriptor owning the stream can make
-invalidating changes. Accordingly multiple file descriptors which
-grabbed different logical streams prevent each other from interfering
-with their settings. When for example video overlay is about to start
-or already in progress, simultaneous video capturing may be restricted
-to the same cropping and image size.</para>
-
- <para>When applications omit the
-<constant>VIDIOC_S_FMT</constant> ioctl its locking side effects are
-implied by the next step, the selection of an I/O method with the
-&VIDIOC-REQBUFS; ioctl or implicit with the first &func-read; or
-&func-write; call.</para>
-
- <para>Generally only one logical stream can be assigned to a
-file descriptor, the exception being drivers permitting simultaneous
-video capturing and overlay using the same file descriptor for
-compatibility with V4L and earlier versions of V4L2. Switching the
-logical stream or returning into "panel mode" is possible by closing
-and reopening the device. Drivers <emphasis>may</emphasis> support a
-switch using <constant>VIDIOC_S_FMT</constant>.</para>
-
- <para>All drivers exchanging data with

- <title>Scaling Adjustments</title>
-
- <para>Video hardware can have various cropping, insertion and
-scaling limitations. It may only scale up or down, support only
-discrete scaling factors, or have different scaling abilities in
-horizontal and vertical direction. Also it may not support scaling at
-all. At the same time the &v4l2-crop; rectangle may have to be
-aligned, and both the source and target rectangles may have arbitrary
-upper and lower size limits. In particular the maximum
-<structfield>width</structfield> and <structfield>height</structfield>
-in &v4l2-crop; may be smaller than the
-&v4l2-cropcap;.<structfield>bounds</structfield> area. Therefore, as
-usual, drivers are expected to adjust the requested parameters and
-return the actual values selected.</para>
-
- <para>Applications can change the source or the target rectangle
-first, as they may prefer a particular image size or a certain area in
-the video signal. If the driver has to adjust both to satisfy hardware
-limitations, the last requested rectangle shall take priority, and the
-driver should preferably adjust the opposite one. The &VIDIOC-TRY-FMT;
-ioctl however shall not change the driver state and therefore only
-adjust the requested rectangle.</para>
-
- <para>Suppose scaling on a video capture device is restricted to
-a factor 1:1 or 2:1 in either direction and the target image size must
-be a multiple of 16&nbsp;&times;&nbsp;16 pixels. The source cropping
-rectangle is set to defaults, which are also the upper limit in this
-example, of 640&nbsp;&times;&nbsp;400 pixels at offset 0,&nbsp;0. An
-application requests an image size of 300&nbsp;&times;&nbsp;225
-pixels, assuming video will be scaled down from the "full picture"
-accordingly. The driver sets the image size to the closest possible
-values 304&nbsp;&times;&nbsp;224, then chooses the cropping rectangle
-closest to the requested size, that is 608&nbsp;&times;&nbsp;224
-(224&nbsp;&times;&nbsp;2:1 would exceed the limit 400). The offset
-0,&nbsp;0 is still valid, thus unmodified. Given the default cropping
-rectangle reported by <constant>VIDIOC_CROPCAP</constant> the
-application can easily propose another offset to center the cropping
-rectangle.</para>
-
- <para>Now the application may insist on covering an area using a
-picture aspect ratio closer to the original request, so it asks for a
-cropping rectangle of 608&nbsp;&times;&nbsp;456 pixels. The present
-scaling factors limit cropping to 640&nbsp;&times;&nbsp;384, so the
-driver returns the cropping size 608&nbsp;&times;&nbsp;384 and adjusts
-the image size to closest possible 304&nbsp;&times;&nbsp;192.</para>

-
- <para>Streaming parameters are intended to optimize the video
-capture process as well as I/O. Presently applications can request a
-high quality capture mode with the &VIDIOC-S-PARM; ioctl.</para>
-
- <para>The current video standard determines a nominal number of
-frames per second. If less than this number of frames is to be
-captured or output, applications can request frame skipping or
-duplicating on the driver side. This is especially useful when using
-the &func-read; or &func-write;, which are not augmented by timestamps
-or sequence counters, and to avoid unnecessary data copying.</para>
-
- <para>Finally these ioctls can be used to determine the number of
-buffers used internally by a driver in read/write mode. For
-implications see the section discussing the &func-read;
-function.</para>
-
- <para>To get and set the streaming parameters applications call
-the &VIDIOC-G-PARM; and &VIDIOC-S-PARM; ioctl, respectively. They take
-a pointer to a &v4l2-streamparm;, which contains a union holding
-separate parameters for input and output devices.</para>
-
- <para>These ioctls are optional, drivers need not implement
-them. If so, they return the &EINVAL;.</para>

-
- <para>The Video For Linux API was first introduced in Linux 2.1 to
-unify and replace various TV and radio device related interfaces,
-developed independently by driver writers in prior years. Starting
-with Linux 2.5 the much improved V4L2 API replaces the V4L API.
-The support for the old V4L calls were removed from Kernel, but the
-library <xref linkend="libv4l" /> supports the conversion of a V4L
-API system call into a V4L2 one.</para>
-
- <section>
- <title>Opening and Closing Devices</title>
-
- <para>For compatibility reasons the character device file names
-recommended for V4L2 video capture, overlay, radio and raw
-vbi capture devices did not change from those used by V4L. They are
-listed in <xref linkend="devices" /> and below in <xref
- linkend="v4l-dev" />.</para>
-
- <para>The teletext devices (minor range 192-223) have been removed in
-V4L2 and no longer exist. There is no hardware available anymore for handling
-pure teletext. Instead raw or sliced VBI is used.</para>
-
- <para>The V4L <filename>videodev</filename> module automatically
-assigns minor numbers to drivers in load order, depending on the
-registered device type. We recommend that V4L2 drivers by default
-register devices with the same numbers, but the system administrator
-can assign arbitrary minor numbers using driver module options. The
-major device number remains 81.</para>

- <para>Unlike the <structfield>tuners</structfield> field
-expressing the number of tuners of this input, V4L2 assumes each video
-input is connected to at most one tuner. However a tuner can have more
-than one input, &ie; RF connectors, and a device can have multiple
-tuners. The index number of the tuner associated with the input, if
-any, is stored in field <structfield>tuner</structfield> of
-&v4l2-input;. Enumeration of tuners is discussed in <xref
- linkend="tuner" />.</para>
-
- <para>The redundant <constant>VIDEO_VC_TUNER</constant> flag was
-dropped. Video inputs associated with a tuner are of type
-<constant>V4L2_INPUT_TYPE_TUNER</constant>. The
-<constant>VIDEO_VC_AUDIO</constant> flag was replaced by the
-<structfield>audioset</structfield> field. V4L2 considers devices with
-up to 32 audio inputs. Each set bit in the
-<structfield>audioset</structfield> field represents one audio input
-this video input combines with. For information about audio inputs and
-how to switch between them see <xref linkend="audio" />.</para>
-
- <para>The <structfield>norm</structfield> field describing the
-supported video standards was replaced by
-<structfield>std</structfield>. The V4L specification mentions a flag
-<constant>VIDEO_VC_NORM</constant> indicating whether the standard can
-be changed. This flag was a later addition together with the

-covered in <xref linkend="tuner" />.</para>
-
- <para>The <structfield>tuner</structfield> field counting tuners
-was renamed to <structfield>index</structfield>. The fields

-
- <para>The <constant>VIDEO_TUNER_PAL</constant>,
-<constant>VIDEO_TUNER_NTSC</constant> and

-video standards were dropped. This information is now contained in the
-associated &v4l2-input;. No replacement exists for the
-<constant>VIDEO_TUNER_NORM</constant> flag indicating whether the
-video standard can be switched. The <structfield>mode</structfield>
-field to select a different video standard was replaced by a whole new
-set of ioctls and structures described in <xref linkend="standard" />.
-Due to its ubiquity it should be mentioned the BTTV driver supports
-several standards in addition to the regular
-<constant>VIDEO_MODE_PAL</constant> (0),
-<constant>VIDEO_MODE_NTSC</constant>,
-<constant>VIDEO_MODE_SECAM</constant> and
-<constant>VIDEO_MODE_AUTO</constant> (3). Namely N/PAL Argentina,
-M/PAL, N/PAL, and NTSC Japan with numbers 3-6 (sic).</para>

- <title>Changes of the V4L2 API</title>
-
- <para>Soon after the V4L API was added to the kernel it was
-criticised as too inflexible. In August 1998 Bill Dirks proposed a
-number of improvements and began to work on documentation, example
-drivers and applications. With the help of other volunteers this
-eventually became the V4L2 API, not just an extension but a
-replacement for the V4L API. However it took another four years and
-two stable kernel releases until the new API was finally accepted for
-inclusion into the kernel in its present form.</para>

-
- <para>1998-09-10: New video standard interface.</para>
-
- <para>1998-09-18: The <constant>VIDIOC_NONCAP</constant> ioctl
-was replaced by the otherwise meaningless <constant>O_TRUNC</constant>
-&func-open; flag, and the aliases <constant>O_NONCAP</constant> and
-<constant>O_NOIO</constant> were defined. Applications can set this
-flag if they intend to access controls only, as opposed to capture
-applications which need exclusive access. The
-<constant>VIDEO_STD_XXX</constant> identifiers are now ordinals
-instead of flags, and the <function>video_std_construct()</function>
-helper function takes id and transmission arguments.</para>
-
- <para>1998-09-28: Revamped video standard. Made video controls
-individually enumerable.</para>
-
- <para>1998-10-02: The <structfield>id</structfield> field was
-removed from struct <structname>video_standard</structname> and the
-color subcarrier fields were renamed. The &VIDIOC-QUERYSTD; ioctl was
-renamed to &VIDIOC-ENUMSTD;, &VIDIOC-G-INPUT; to &VIDIOC-ENUMINPUT;. A
-first draft of the Codec API was released.</para>

-was changed to a 64 bit integer, containing the sampling or output
-time of the frame in nanoseconds. Additionally timestamps will be in
-absolute system time, not starting from zero at the beginning of a
-stream. The data type name for timestamps is stamp_t, defined as a
-signed 64-bit integer. Output devices should not send a buffer out
-until the time in the timestamp field has arrived. I would like to
-follow SGI's lead, and adopt a multimedia timestamping system like
-their UST (Unadjusted System Time). See
-http://web.archive.org/web/*/http://reality.sgi.com
-/cpirazzi_engr/lg/time/intro.html.
-UST uses timestamps that are 64-bit signed integers
-(not struct timeval's) and given in nanosecond units. The UST clock
-starts at zero when the system is booted and runs continuously and
-uniformly. It takes a little over 292 years for UST to overflow. There
-is no way to set the UST clock. The regular Linux time-of-day clock
-can be changed periodically, which would cause errors if it were being
-used for timestamping a multimedia stream. A real UST style clock will
-require some support in the kernel that is not there yet. But in
-anticipation, I will change the timestamp field to a 64-bit integer,
-and I will change the v4l2_masterclock_gettime() function (used only
-by drivers) to return a 64-bit integer.</para>

-interface.</para>
-
- <orderedlist>
- <listitem>
- <para>Figures clarifying the line numbering scheme were
-added to the V4L2 API specification. The
-<structfield>start</structfield>[0] and
-<structfield>start</structfield>[1] fields no longer count line
-numbers beginning at zero. Rationale: a) The previous definition was
-unclear. b) The <structfield>start</structfield>[] values are ordinal
-numbers. c) There is no point in inventing a new line numbering
-scheme. We now use line number as defined by ITU-R, period.
-Compatibility: Add one to the start values. Applications depending on
-the previous semantics may not function correctly.</para>
- </listitem>
-
- <listitem>
- <para>The restriction "count[0] &gt; 0 and count[1] &gt; 0"
-has been relaxed to "(count[0] + count[1]) &gt; 0". Rationale:
-Drivers may allocate resources at scan line granularity and some data
-services are transmitted only on the first field. The comment that
-both <structfield>count</structfield> values will usually be equal is
-misleading and pointless and has been removed. This change
-<emphasis>breaks compatibility</emphasis> with earlier versions:
-Drivers may return EINVAL, applications may not function
-correctly.</para>
- </listitem>
-
- <listitem>
- <para>Drivers are again permitted to return negative
-(unknown) start values as proposed earlier. Why this feature was
-dropped is unclear. This change may <emphasis>break
-compatibility</emphasis> with applications depending on the start
-values being positive. The use of <constant>EBUSY</constant> and
-<constant>EINVAL</constant> error codes with the &VIDIOC-S-FMT; ioctl
-was clarified. The &EBUSY; was finally documented, and the

-
- <para>Around October-November 2002, prior to an announced
-feature freeze of Linux 2.5, the API was revised, drawing from
-experience with V4L2 0.20. This unnamed version was finally merged
-into Linux 2.5.46.</para>

- <listitem>
- <para>The &func-open; function requires access mode
-<constant>O_RDWR</constant> regardless of the device type. All V4L2
-drivers exchanging data with applications must support the
-<constant>O_NONBLOCK</constant> flag. The <constant>O_NOIO</constant>
-flag, a V4L2 symbol which aliased the meaningless
-<constant>O_TRUNC</constant> to indicate accesses without data
-exchange (panel applications) was dropped. Drivers must stay in "panel
-mode" until the application attempts to initiate a data exchange, see
-<xref linkend="open" />.</para>
- </listitem>
-
- <listitem>
- <para>The &v4l2-capability; changed dramatically. Note that
-also the size of the structure changed, which is encoded in the ioctl
-request code, thus older V4L2 devices will respond with an &EINVAL; to
-the new &VIDIOC-QUERYCAP; ioctl.</para>
-
- <para>There are new fields to identify the driver, a new RDS
-device function <constant>V4L2_CAP_RDS_CAPTURE</constant>, the
-<constant>V4L2_CAP_AUDIO</constant> flag indicates if the device has
-any audio connectors, another I/O capability
-<constant>V4L2_CAP_ASYNCIO</constant> can be flagged. In response to
-these changes the <structfield>type</structfield> field became a bit
-set and was merged into the <structfield>flags</structfield> field.
-<constant>V4L2_FLAG_TUNER</constant> was renamed to
-<constant>V4L2_CAP_TUNER</constant>,
-<constant>V4L2_CAP_VIDEO_OVERLAY</constant> replaced
-<constant>V4L2_FLAG_PREVIEW</constant> and
-<constant>V4L2_CAP_VBI_CAPTURE</constant> and
-<constant>V4L2_CAP_VBI_OUTPUT</constant> replaced
-<constant>V4L2_FLAG_DATA_SERVICE</constant>.
-<constant>V4L2_FLAG_READ</constant> and

-
- <para>The redundant fields
-<structfield>inputs</structfield>, <structfield>outputs</structfield>
-and <structfield>audios</structfield> were removed. These properties

-is available as described in <xref linkend="format" /> and
-<xref linkend="standard" />.</para>
-
- <para><constant>V4L2_FLAG_SELECT</constant> was removed. We
-believe the select() function is important enough to require support
-of it in all V4L2 drivers exchanging data with applications. The
-redundant <constant>V4L2_FLAG_MONOCHROME</constant> flag was removed,

-<structfield>audioset</structfield> field. Instead of linking one
-video input to one audio input this field reports all audio inputs
-this video input combines with.</para>
-
- <para>New fields are <structfield>tuner</structfield>
-(reversing the former link from tuners to video inputs),

- <para>The &v4l2-audio; field
-<structfield>audio</structfield> was renamed to
-<structfield>index</structfield>, for consistency with other
-structures. A new capability flag
-<constant>V4L2_AUDCAP_STEREO</constant> was added to indicated if the
-audio input in question supports stereo sound.
-<constant>V4L2_AUDCAP_EFFECTS</constant> and the corresponding
-<constant>V4L2_AUDMODE</constant> flags where removed. This can be
-easily implemented using controls. (However the same applies to AVL

-
- <para>In &v4l2-frequency; the
-<structfield>port</structfield> field was replaced by a
-<structfield>tuner</structfield> field containing the respective tuner
-or modulator index number. A tuner <structfield>type</structfield>
-field was added and the <structfield>reserved</structfield> field
-became larger for future extensions (satellite tuners in
-particular).</para>
- </listitem>
-
- <listitem>
- <para>The idea of completely transparent video standards was
-dropped. Experience showed that applications must be able to work with
-video standards beyond presenting the user a menu. Instead of
-enumerating supported standards with an ioctl applications can now
-refer to standards by &v4l2-std-id; and symbols defined in the
-<filename>videodev2.h</filename> header file. For details see <xref
- linkend="standard" />. The &VIDIOC-G-STD; and
-&VIDIOC-S-STD; now take a pointer to this type as argument.
-&VIDIOC-QUERYSTD; was added to autodetect the received standard, if
-the hardware has this capability. In &v4l2-standard; an
-<structfield>index</structfield> field was added for &VIDIOC-ENUMSTD;.
-A &v4l2-std-id; field named <structfield>id</structfield> was added as
-machine readable identifier, also replacing the
-<structfield>transmission</structfield> field. The misleading
-<structfield>framerate</structfield> field was renamed
-to <structfield>frameperiod</structfield>. The now obsolete
-<structfield>colorstandard</structfield> information, originally
-needed to distguish between variations of standards, were
-removed.</para>
-
- <para>Struct <structname>v4l2_enumstd</structname> ceased to
-be. &VIDIOC-ENUMSTD; now takes a pointer to a &v4l2-standard;
-directly. The information which standards are supported by a
-particular video input or output moved into &v4l2-input; and
-&v4l2-output; fields named <structfield>std</structfield>,
-respectively.</para>
- </listitem>
-
- <listitem>
- <para>The &v4l2-queryctrl; fields
-<structfield>category</structfield> and

-implemented as expected and therefore removed.</para>
- </listitem>
-
- <listitem>
- <para>The &VIDIOC-TRY-FMT; ioctl was added to negotiate data
-formats as with &VIDIOC-S-FMT;, but without the overhead of
-programming the hardware and regardless of I/O in progress.</para>
-
- <para>In &v4l2-format; the <structfield>fmt</structfield>
-union was extended to contain &v4l2-window;. All image format
-negotiations are now possible with <constant>VIDIOC_G_FMT</constant>,
-<constant>VIDIOC_S_FMT</constant> and
-<constant>VIDIOC_TRY_FMT</constant>; ioctl. The
-<constant>VIDIOC_G_WIN</constant> and
-<constant>VIDIOC_S_WIN</constant> ioctls to prepare for a video
-overlay were removed. The <structfield>type</structfield> field
-changed to type &v4l2-buf-type; and the buffer type names changed as

- <title>X Video Extension</title>
-
- <para>The X Video Extension (abbreviated XVideo or just Xv) is
-an extension of the X Window system, implemented for example by the
-XFree86 project. Its scope is similar to V4L2, an API to video capture
-and output devices for X clients. Xv allows applications to display
-live video in a window, send window contents to a TV output, and
-capture or output still images in XPixmaps<footnote>
- <para>This is not implemented in XFree86.</para>
- </footnote>. With their implementation XFree86 makes the
-extension available across many operating systems and
-architectures.</para>
-
- <para>Because the driver is embedded into the X server Xv has a
-number of advantages over the V4L2 <link linkend="overlay">video
-overlay interface</link>. The driver can easily determine the overlay
-target, &ie; visible graphics memory or off-screen buffers for a
-destructive overlay. It can program the RAMDAC for a non-destructive
-overlay, scaling or color-keying, or the clipping functions of the
-video capture hardware, always in sync with drawing operations or
-windows moving or changing their stacking order.</para>
-
- <para>To combine the advantages of Xv and V4L a special Xv
-driver exists in XFree86 and XOrg, just programming any overlay capable
-Video4Linux device it finds. To enable it
-<filename>/etc/X11/XF86Config</filename> must contain these lines:</para>
- <para><screen>
-Section "Module"
- Load "v4l"
-EndSection</screen></para>
-
- <para>As of XFree86 4.2 this driver still supports only V4L
-ioctls, however it should work just fine with all V4L2 devices through
-the V4L2 backward-compatibility layer. Since V4L2 permits multiple
-opens it is possible (if supported by the V4L2 driver) to capture
-video while an X client requested video overlay. Restrictions of
-simultaneous capturing and overlay are discussed in <xref
- linkend="overlay" /> apply.</para>
-
- <para>Only marginally related to V4L2, XFree86 extended Xv to
-support hardware YUV to RGB conversion and scaling for faster video
-playback, and added an interface to MPEG-2 decoding hardware. This API
-is useful to display images captured with V4L2 devices.</para>

- <title>User Controls</title>
-
- <para>Devices typically have a number of user-settable controls
-such as brightness, saturation and so on, which would be presented to
-the user on a graphical user interface. But, different devices
-will have different controls available, and furthermore, the range of
-possible values, and the default value will vary from device to
-device. The control ioctls provide the information and a mechanism to
-create a nice user interface for these controls that will work
-correctly with any device.</para>
-
- <para>All controls are accessed using an ID value. V4L2 defines
-several IDs for specific purposes. Drivers can also implement their
-own custom controls using <constant>V4L2_CID_PRIVATE_BASE</constant>
-<footnote><para>The use of <constant>V4L2_CID_PRIVATE_BASE</constant>
-is problematic because different drivers may use the same
-<constant>V4L2_CID_PRIVATE_BASE</constant> ID for different controls.
-This makes it hard to programatically set such controls since the meaning
-of the control with that ID is driver dependent. In order to resolve this
-drivers use unique IDs and the <constant>V4L2_CID_PRIVATE_BASE</constant>
-IDs are mapped to those unique IDs by the kernel. Consider these
-<constant>V4L2_CID_PRIVATE_BASE</constant> IDs as aliases to the real
-IDs.</para>
-<para>Many applications today still use the <constant>V4L2_CID_PRIVATE_BASE</constant>
-IDs instead of using &VIDIOC-QUERYCTRL; with the <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>
-flag to enumerate all IDs, so support for <constant>V4L2_CID_PRIVATE_BASE</constant>
-is still around.</para></footnote>
-and higher values. The pre-defined control IDs have the prefix
-<constant>V4L2_CID_</constant>, and are listed in <xref
-linkend="control-id" />. The ID is used when querying the attributes of
-a control, and when getting or setting the current value.</para>
-
- <para>Generally applications should present controls to the user
-without assumptions about their purpose. Each control comes with a
-name string the user is supposed to understand. When the purpose is
-non-intuitive the driver writer should provide a user manual, a user
-interface plug-in or a driver specific panel application. Predefined
-IDs were introduced to change a few controls programmatically, for
-example to mute a device during a channel switch.</para>
-
- <para>Drivers may enumerate different controls after switching
-the current video input or output, tuner or modulator, or audio input
-or output. Different in the sense of other bounds, another default and
-current value, step size or other menu items. A control with a certain
-<emphasis>custom</emphasis> ID can also change name and
-type.</para>
-
- <para>If a control is not applicable to the current configuration
-of the device (for example, it doesn't apply to the current video input)
-drivers set the <constant>V4L2_CTRL_FLAG_INACTIVE</constant> flag.</para>
-
- <para>Control values are stored globally, they do not
-change when switching except to stay within the reported bounds. They
-also do not change &eg; when the device is opened or closed, when the
-tuner radio frequency is changed or generally never without
-application request.</para>
-
- <para>V4L2 specifies an event mechanism to notify applications
-when controls change value (see &VIDIOC-SUBSCRIBE-EVENT;, event
-<constant>V4L2_EVENT_CTRL</constant>), panel applications might want to make
-use of that in order to always reflect the correct control value.</para>
-
- <para>
- All controls use machine endianness.

- <section>
- <title>Introduction</title>
-
- <para>The control mechanism as originally designed was meant
-to be used for user settings (brightness, saturation, etc). However,
-it turned out to be a very useful model for implementing more
-complicated driver APIs where each driver implements only a subset of
-a larger API.</para>
-
- <para>The MPEG encoding API was the driving force behind
-designing and implementing this extended control mechanism: the MPEG
-standard is quite large and the currently supported hardware MPEG
-encoders each only implement a subset of this standard. Further more,
-many parameters relating to how the video is encoded into an MPEG
-stream are specific to the MPEG encoding chip since the MPEG standard
-only defines the format of the resulting MPEG stream, not how the
-video is actually encoded into that format.</para>
-
- <para>Unfortunately, the original control API lacked some
-features needed for these new uses and so it was extended into the
-(not terribly originally named) extended control API.</para>
-
- <para>Even though the MPEG encoding API was the first effort
-to use the Extended Control API, nowadays there are also other classes
-of Extended Controls, such as Camera Controls and FM Transmitter Controls.
-The Extended Controls API as well as all Extended Controls classes are
-described in the following text.</para>
- </section>
-
- <section>
- <title>The Extended Control API</title>
-
- <para>Three new ioctls are available: &VIDIOC-G-EXT-CTRLS;,
-&VIDIOC-S-EXT-CTRLS; and &VIDIOC-TRY-EXT-CTRLS;. These ioctls act on
-arrays of controls (as opposed to the &VIDIOC-G-CTRL; and
-&VIDIOC-S-CTRL; ioctls that act on a single control). This is needed
-since it is often required to atomically change several controls at
-once.</para>
-
- <para>Each of the new ioctls expects a pointer to a
-&v4l2-ext-controls;. This structure contains a pointer to the control
-array, a count of the number of controls in that array and a control
-class. Control classes are used to group similar controls into a
-single class. For example, control class
-<constant>V4L2_CTRL_CLASS_USER</constant> contains all user controls
-(&ie; all controls that can also be set using the old
-<constant>VIDIOC_S_CTRL</constant> ioctl). Control class
-<constant>V4L2_CTRL_CLASS_MPEG</constant> contains all controls
-relating to MPEG encoding, etc.</para>
-
- <para>All controls in the control array must belong to the
-specified control class. An error is returned if this is not the
-case.</para>
-
- <para>It is also possible to use an empty control array (count
-== 0) to check whether the specified control class is
-supported.</para>
-
- <para>The control array is a &v4l2-ext-control; array. The
-<structname>v4l2_ext_control</structname> structure is very similar to
-&v4l2-control;, except for the fact that it also allows for 64-bit
-values and pointers to be passed.</para>
-
- <para>Since the &v4l2-ext-control; supports pointers it is now
-also possible to have controls with compound types such as N-dimensional arrays
-and/or structures. You need to specify the <constant>V4L2_CTRL_FLAG_NEXT_COMPOUND</constant>
-when enumerating controls to actually be able to see such compound controls.
-In other words, these controls with compound types should only be used
-programmatically.</para>
-
- <para>Since such compound controls need to expose more information
-about themselves than is possible with &VIDIOC-QUERYCTRL; the
-&VIDIOC-QUERY-EXT-CTRL; ioctl was added. In particular, this ioctl gives
-the dimensions of the N-dimensional array if this control consists of more than
-one element.</para>
-
- <para>It is important to realize that due to the flexibility of
-controls it is necessary to check whether the control you want to set
-actually is supported in the driver and what the valid range of values
-is. So use the &VIDIOC-QUERYCTRL; (or &VIDIOC-QUERY-EXT-CTRL;) and
-&VIDIOC-QUERYMENU; ioctls to check this. Also note that it is possible
-that some of the menu indices in a control of type
-<constant>V4L2_CTRL_TYPE_MENU</constant> may not be supported
-(<constant>VIDIOC_QUERYMENU</constant> will return an error). A good
-example is the list of supported MPEG audio bitrates. Some drivers only
-support one or two bitrates, others support a wider range.</para>
-
- <para>
- All controls use machine endianness.
- </para>
- </section>
-
- <section>
- <title>Enumerating Extended Controls</title>
-
- <para>The recommended way to enumerate over the extended
-controls is by using &VIDIOC-QUERYCTRL; in combination with the
-<constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> flag:</para>
-
- <informalexample>
- <programlisting>
-&v4l2-queryctrl; qctrl;
-
-qctrl.id = V4L2_CTRL_FLAG_NEXT_CTRL;
-while (0 == ioctl (fd, &VIDIOC-QUERYCTRL;, &amp;qctrl)) {
- /* ... */
- qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
-}
-</programlisting>
- </informalexample>
-
- <para>The initial control ID is set to 0 ORed with the
-<constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> flag. The
-<constant>VIDIOC_QUERYCTRL</constant> ioctl will return the first
-control with a higher ID than the specified one. When no such controls
-are found an error is returned.</para>
-
- <para>If you want to get all controls within a specific control
-class, then you can set the initial
-<structfield>qctrl.id</structfield> value to the control class and add
-an extra check to break out of the loop when a control of another
-control class is found:</para>
-
- <informalexample>
- <programlisting>
-qctrl.id = V4L2_CTRL_CLASS_MPEG | V4L2_CTRL_FLAG_NEXT_CTRL;
-while (0 == ioctl(fd, &VIDIOC-QUERYCTRL;, &amp;qctrl)) {
- if (V4L2_CTRL_ID2CLASS(qctrl.id) != V4L2_CTRL_CLASS_MPEG)
- break;
- /* ... */
- qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
-}
-</programlisting>
- </informalexample>
-
- <para>The 32-bit <structfield>qctrl.id</structfield> value is
-subdivided into three bit ranges: the top 4 bits are reserved for
-flags (&eg; <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>) and are not
-actually part of the ID. The remaining 28 bits form the control ID, of
-which the most significant 12 bits define the control class and the
-least significant 16 bits identify the control within the control
-class. It is guaranteed that these last 16 bits are always non-zero
-for controls. The range of 0x1000 and up are reserved for
-driver-specific controls. The macro
-<constant>V4L2_CTRL_ID2CLASS(id)</constant> returns the control class
-ID based on a control ID.</para>
-
- <para>If the driver does not support extended controls, then
-<constant>VIDIOC_QUERYCTRL</constant> will fail when used in
-combination with <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>. In
-that case the old method of enumerating control should be used (see
-<xref linkend="enum_all_controls" />). But if it is supported, then it is guaranteed to enumerate over
-all controls, including driver-private controls.</para>
- </section>
-
- <section>
- <title>Creating Control Panels</title>
-
- <para>It is possible to create control panels for a graphical
-user interface where the user can select the various controls.
-Basically you will have to iterate over all controls using the method
-described above. Each control class starts with a control of type
-<constant>V4L2_CTRL_TYPE_CTRL_CLASS</constant>.
-<constant>VIDIOC_QUERYCTRL</constant> will return the name of this
-control class which can be used as the title of a tab page within a
-control panel.</para>
-
- <para>The flags field of &v4l2-queryctrl; also contains hints on
-the behavior of the control. See the &VIDIOC-QUERYCTRL; documentation

- <title>Video Overlay Interface</title>
- <subtitle>Also known as Framebuffer Overlay or Previewing</subtitle>
-
- <para>Video overlay devices have the ability to genlock (TV-)video
-into the (VGA-)video signal of a graphics card, or to store captured
-images directly in video memory of a graphics card, typically with
-clipping. This can be considerable more efficient than capturing
-images and displaying them by other means. In the old days when only
-nuclear power plants needed cooling towers this used to be the only
-way to put live video into a window.</para>
-
- <para>Video overlay devices are accessed through the same character
-special files as <link linkend="capture">video capture</link> devices.
-Note the default function of a <filename>/dev/video</filename> device
-is video capturing. The overlay function is only available after
-calling the &VIDIOC-S-FMT; ioctl.</para>
-
- <para>The driver may support simultaneous overlay and capturing
-using the read/write and streaming I/O methods. If so, operation at
-the nominal frame rate of the video standard is not guaranteed. Frames
-may be directed away from overlay to capture, or one field may be used
-for overlay and the other for capture if the capture parameters permit
-this.</para>
-
- <para>Applications should use different file descriptors for
-capturing and overlay. This must be supported by all drivers capable
-of simultaneous capturing and overlay. Optionally these drivers may
-also permit capturing and overlay with a single file descriptor for
-compatibility with V4L and earlier versions of V4L2.<footnote>
- <para>A common application of two file descriptors is the
-XFree86 <link linkend="xvideo">Xv/V4L</link> interface driver and
-a V4L2 application. While the X server controls video overlay, the
-application can take advantage of memory mapping and DMA.</para>
- <para>In the opinion of the designers of this API, no driver
-writer taking the efforts to support simultaneous capturing and
-overlay will restrict this ability by requiring a single file
-descriptor, as in V4L and earlier versions of V4L2. Making this
-optional means applications depending on two file descriptors need
-backup routines to be compatible with all drivers, which is
-considerable more work than using two fds in applications which do
-not. Also two fd's fit the general concept of one file descriptor for
-each logical stream. Hence as a complexity trade-off drivers
-<emphasis>must</emphasis> support two file descriptors and
-<emphasis>may</emphasis> support single fd operation.</para>

-
- <para>Before overlay can commence applications must program the
-driver with frame buffer parameters, namely the address and size of
-the frame buffer and the image format, for example RGB 5:6:5. The
-&VIDIOC-G-FBUF; and &VIDIOC-S-FBUF; ioctls are available to get
-and set these parameters, respectively. The
-<constant>VIDIOC_S_FBUF</constant> ioctl is privileged because it
-allows to set up DMA into physical memory, bypassing the memory
-protection mechanisms of the kernel. Only the superuser can change the
-frame buffer address and size. Users are not supposed to run TV
-applications as root or with SUID bit set. A small helper application
-with suitable privileges should query the graphics system and program
-the V4L2 driver at the appropriate time.</para>
-
- <para>Some devices add the video overlay to the output signal
-of the graphics card. In this case the frame buffer is not modified by
-the video device, and the frame buffer address and pixel format are
-not needed by the driver. The <constant>VIDIOC_S_FBUF</constant> ioctl
-is not privileged. An application can check for this type of device by
-calling the <constant>VIDIOC_G_FBUF</constant> ioctl.</para>

- <title>Overlay Window</title>
-
- <para>The overlaid image is determined by cropping and overlay
-window parameters. The former select an area of the video picture to
-capture, the latter how images are overlaid and clipped. Cropping
-initialization at minimum requires to reset the parameters to
-defaults. An example is given in <xref linkend="crop" />.</para>
-
- <para>The overlay window is described by a &v4l2-window;. It
-defines the size of the image, its position over the graphics surface
-and the clipping to be applied. To get the current parameters
-applications set the <structfield>type</structfield> field of a
-&v4l2-format; to <constant>V4L2_BUF_TYPE_VIDEO_OVERLAY</constant> and
-call the &VIDIOC-G-FMT; ioctl. The driver fills the
-<structname>v4l2_window</structname> substructure named
-<structfield>win</structfield>. It is not possible to retrieve a
-previously programmed clipping list or bitmap.</para>
-
- <para>To program the overlay window applications set the
-<structfield>type</structfield> field of a &v4l2-format; to
-<constant>V4L2_BUF_TYPE_VIDEO_OVERLAY</constant>, initialize the
-<structfield>win</structfield> substructure and call the
-&VIDIOC-S-FMT; ioctl. The driver adjusts the parameters against
-hardware limits and returns the actual parameters as
-<constant>VIDIOC_G_FMT</constant> does. Like
-<constant>VIDIOC_S_FMT</constant>, the &VIDIOC-TRY-FMT; ioctl can be

-
- <para>To find out which data services are supported by the
-hardware applications can call the &VIDIOC-G-SLICED-VBI-CAP; ioctl.
-All drivers implementing the sliced VBI interface must support this
-ioctl. The results may differ from those of the &VIDIOC-S-FMT; ioctl
-when the number of VBI lines the hardware can capture or output per
-frame, or the number of services it can identify on a given line are
-limited. For example on PAL line 16 the hardware may be able to look
-for a VPS or Teletext signal, but not both at the same time.</para>
-
- <para>To determine the currently selected services applications
-set the <structfield>type </structfield> field of &v4l2-format; to
-<constant> V4L2_BUF_TYPE_SLICED_VBI_CAPTURE</constant> or <constant>
-V4L2_BUF_TYPE_SLICED_VBI_OUTPUT</constant>, and the &VIDIOC-G-FMT;
-ioctl fills the <structfield>fmt.sliced</structfield> member, a
-&v4l2-sliced-vbi-format;.</para>
-
- <para>Applications can request different parameters by
-initializing or modifying the <structfield>fmt.sliced</structfield>
-member and calling the &VIDIOC-S-FMT; ioctl with a pointer to the
-<structname>v4l2_format</structname> structure.</para>
-
- <para>The sliced VBI API is more complicated than the raw VBI API
-because the hardware must be told which VBI service to expect on each
-scan line. Not all services may be supported by the hardware on all
-lines (this is especially true for VBI output where Teletext is often
-unsupported and other services can only be inserted in one specific
-line). In many cases, however, it is sufficient to just set the
-<structfield>service_set</structfield> field to the required services
-and let the driver fill the <structfield>service_lines</structfield>
-array according to hardware capabilities. Only if more precise control
-is needed should the programmer set the
-<structfield>service_lines</structfield> array explicitly.</para>
-
- <para>The &VIDIOC-S-FMT; ioctl modifies the parameters
-according to hardware capabilities. When the driver allocates
-resources at this point, it may return an &EBUSY; if the required
-resources are temporarily unavailable. Other resource allocation
-points which may return <errorcode>EBUSY</errorcode> can be the
-&VIDIOC-STREAMON; ioctl and the first &func-read;, &func-write; and
-&func-select; call.</para>

- <title>Sub-device Interface</title>
-
- <para>The complex nature of V4L2 devices, where hardware is often made of
- several integrated circuits that need to interact with each other in a
- controlled way, leads to complex V4L2 drivers. The drivers usually reflect
- the hardware model in software, and model the different hardware components
- as software blocks called sub-devices.</para>
-
- <para>V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver
- implements the media device API, they will automatically inherit from media
- entities. Applications will be able to enumerate the sub-devices and discover
- the hardware topology using the media entities, pads and links enumeration
- API.</para>
-
- <para>In addition to make sub-devices discoverable, drivers can also choose
- to make them directly configurable by applications. When both the sub-device
- driver and the V4L2 device driver support this, sub-devices will feature a

- <title>Controls</title>
- <para>Most V4L2 controls are implemented by sub-device hardware. Drivers
- usually merge all controls and expose them through video device nodes.
- Applications can control all sub-devices through a single interface.</para>
-
- <para>Complex devices sometimes implement the same control in different
- pieces of hardware. This situation is common in embedded platforms, where
- both sensors and image processing hardware implement identical functions,
- such as contrast adjustment, white balance or faulty pixels correction. As
- the V4L2 controls API doesn't support several identical controls in a single
- device, all but one of the identical controls are hidden.</para>
-
- <para>Applications can access those hidden controls through the sub-device
- node with the V4L2 control API described in <xref linkend="control" />. The
- ioctls behave identically as when issued on V4L2 device nodes, with the
- exception that they deal only with controls implemented in the sub-device.
- </para>
-
- <para>Depending on the driver, those controls might also be exposed through
- one (or several) V4L2 device nodes.</para>

- <title>Events</title>
- <para>V4L2 sub-devices can notify applications of events as described in
- <xref linkend="event" />. The API behaves identically as when used on V4L2
- device nodes, with the exception that it only deals with events generated by
- the sub-device. Depending on the driver, those events might also be reported
- on one (or several) V4L2 device nodes.</para>

- and/or output.</para>
-
- <para>For complex devices, such as often found in embedded systems,
- identical image sizes at the output of a pipeline can be achieved using

- <para>The sensor scaler is usually of less quality than the host scaler, but

- on the use case (quality vs. speed), the pipeline must be configured
- differently. Applications need to configure the formats at every point in
- the pipeline explicitly.</para>
-
- <para>Drivers that implement the <link linkend="media-controller-intro">media
- API</link> can expose pad-level image format configuration to applications.
- When they do, applications can use the &VIDIOC-SUBDEV-G-FMT; and
- &VIDIOC-SUBDEV-S-FMT; ioctls. to negotiate formats on a per-pad basis.</para>
-
- <para>Applications are responsible for configuring coherent parameters on
- the whole pipeline and making sure that connected pads have compatible
- formats. The pipeline is checked for formats mismatch at &VIDIOC-STREAMON;
- time, and an &EPIPE; is then returned if the configuration is
- invalid.</para>
-
- <para>Pad-level image format configuration support can be tested by calling
- the &VIDIOC-SUBDEV-G-FMT; ioctl on pad 0. If the driver returns an &EINVAL;
- pad-level format configuration is not supported by the sub-device.</para>
-
- <section>
- <title>Format Negotiation</title>
-
- <para>Acceptable formats on pads can (and usually do) depend on a number
- of external parameters, such as formats on other pads, active links, or
- even controls. Finding a combination of formats on all pads in a video
- pipeline, acceptable to both application and driver, can't rely on formats
- enumeration only. A format negotiation mechanism is required.</para>
-
- <para>Central to the format negotiation mechanism are the get/set format
- operations. When called with the <structfield>which</structfield> argument
- set to <constant>V4L2_SUBDEV_FORMAT_TRY</constant>, the
- &VIDIOC-SUBDEV-G-FMT; and &VIDIOC-SUBDEV-S-FMT; ioctls operate on a set of
- formats parameters that are not connected to the hardware configuration.
- Modifying those 'try' formats leaves the device state untouched (this
- applies to both the software state stored in the driver and the hardware
- state stored in the device itself).</para>
-
- <para>While not kept as part of the device state, try formats are stored
- in the sub-device file handles. A &VIDIOC-SUBDEV-G-FMT; call will return
- the last try format set <emphasis>on the same sub-device file
- handle</emphasis>. Several applications querying the same sub-device at
- the same time will thus not interact with each other.</para>
-
- <para>To find out whether a particular format is supported by the device,
- applications use the &VIDIOC-SUBDEV-S-FMT; ioctl. Drivers verify and, if
- needed, change the requested <structfield>format</structfield> based on
- device requirements and return the possibly modified value. Applications
- can then choose to try a different format or accept the returned value and
- continue.</para>
-
- <para>Formats returned by the driver during a negotiation iteration are
- guaranteed to be supported by the device. In particular, drivers guarantee
- that a returned format will not be further changed if passed to an
- &VIDIOC-SUBDEV-S-FMT; call as-is (as long as external parameters, such as
- formats on other pads or links' configuration are not changed).</para>
-
- <para>Drivers automatically propagate formats inside sub-devices. When a
- try or active format is set on a pad, corresponding formats on other pads
- of the same sub-device can be modified by the driver. Drivers are free to
- modify formats as required by the device. However, they should comply with
- the following rules when possible:
- <itemizedlist>
- <listitem><para>Formats should be propagated from sink pads to source pads.
- Modifying a format on a source pad should not modify the format on any
- sink pad.</para></listitem>
- <listitem><para>Sub-devices that scale frames using variable scaling factors
- should reset the scale factors to default values when sink pads formats
- are modified. If the 1:1 scaling ratio is supported, this means that
- source pads formats should be reset to the sink pads formats.</para></listitem>
- </itemizedlist>
- </para>
-
- <para>Formats are not propagated across links, as that would involve
- propagating them from one sub-device file handle to another. Applications
- must then take care to configure both ends of every link explicitly with
- compatible formats. Identical formats on the two ends of a link are
- guaranteed to be compatible. Drivers are free to accept different formats
- matching device requirements as being compatible.</para>

- <title>Selections: cropping, scaling and composition</title>
-
- <para>Many sub-devices support cropping frames on their input or output
- pads (or possible even on both). Cropping is used to select the area of
- interest in an image, typically on an image sensor or a video decoder. It can
- also be used as part of digital zoom implementations to select the area of
- the image that will be scaled up.</para>
-
- <para>Crop settings are defined by a crop rectangle and represented in a
- &v4l2-rect; by the coordinates of the top left corner and the rectangle
- size. Both the coordinates and sizes are expressed in pixels.</para>
-
- <para>As for pad formats, drivers store try and active
- rectangles for the selection targets <xref
- linkend="v4l2-selections-common" />.</para>
-
- <para>On sink pads, cropping is applied relative to the
- current pad format. The pad format represents the image size as
- received by the sub-device from the previous block in the
- pipeline, and the crop rectangle represents the sub-image that
- will be transmitted further inside the sub-device for
- processing.</para>
-
- <para>The scaling operation changes the size of the image by
- scaling it to new dimensions. The scaling ratio isn't specified
- explicitly, but is implied from the original and scaled image
- sizes. Both sizes are represented by &v4l2-rect;.</para>
-
- <para>Scaling support is optional. When supported by a subdev,
- the crop rectangle on the subdev's sink pad is scaled to the
- size configured using the &VIDIOC-SUBDEV-S-SELECTION; IOCTL
- using <constant>V4L2_SEL_TGT_COMPOSE</constant>
- selection target on the same pad. If the subdev supports scaling
- but not composing, the top and left values are not used and must
- always be set to zero.</para>
-
- <para>On source pads, cropping is similar to sink pads, with the
- exception that the source size from which the cropping is
- performed, is the COMPOSE rectangle on the sink pad. In both
- sink and source pads, the crop rectangle must be entirely
- contained inside the source image size for the crop

- <para>This interface was aimed at devices receiving and demodulating

-Teletext packages and storing formatted pages in cache memory. Such

- <para>However, teletext decoders were quickly replaced by more

- <para>V4L2 is a two-layer driver system. The top layer is the "videodev"
-kernel module. When videodev initializes it registers as character device
-with major number 81, and it registers a set of file operations. All V4L2
-drivers are really clients of videodev, which calls V4L2 drivers through
-driver method functions. V4L2 drivers are also written as kernel modules.
-After probing the hardware they register one or more devices with
-videodev.</para>

-
- <para>With the <function>poll()</function> function applications
-can suspend execution until the driver has captured data or is ready
-to accept data for output.</para>
-
- <para>When streaming I/O has been negotiated this function waits
-until a buffer has been filled by the capture device and can be dequeued
-with the &VIDIOC-DQBUF; ioctl. For output devices this function waits
-until the device is ready to accept a new buffer to be queued up with
-the &VIDIOC-QBUF; ioctl for display. When buffers are already in the outgoing
-queue of the driver (capture) or the incoming queue isn't full (display)
-the function returns immediately.</para>
-
- <para>On success <function>poll()</function> returns the number of
-file descriptors that have been selected (that is, file descriptors
-for which the <structfield>revents</structfield> field of the
-respective <structname>pollfd</structname> structure is non-zero).
-Capture devices set the <constant>POLLIN</constant> and
-<constant>POLLRDNORM</constant> flags in the
-<structfield>revents</structfield> field, output devices the
-<constant>POLLOUT</constant> and <constant>POLLWRNORM</constant>
-flags. When the function timed out it returns a value of zero, on
-failure it returns <returnvalue>-1</returnvalue> and the
-<varname>errno</varname> variable is set appropriately. When the
-application did not call &VIDIOC-STREAMON; the
-<function>poll()</function> function succeeds, but sets the
-<constant>POLLERR</constant> flag in the
-<structfield>revents</structfield> field. When the
-application has called &VIDIOC-STREAMON; for a capture device but hasn't
-yet called &VIDIOC-QBUF;, the <function>poll()</function> function
-succeeds and sets the <constant>POLLERR</constant> flag in the
-<structfield>revents</structfield> field. For output devices this
-same situation will cause <function>poll()</function> to succeed
-as well, but it sets the <constant>POLLOUT</constant> and
-<constant>POLLWRNORM</constant> flags in the <structfield>revents</structfield>
-field.</para>
-
- <para>If an event occurred (see &VIDIOC-DQEVENT;) then
-<constant>POLLPRI</constant> will be set in the <structfield>revents</structfield>
-field and <function>poll()</function> will return.</para>
-
- <para>When use of the <function>read()</function> function has
-been negotiated and the driver does not capture yet, the
-<function>poll</function> function starts capturing. When that fails
-it returns a <constant>POLLERR</constant> as above. Otherwise it waits
-until data has been captured and can be read. When the driver captures
-continuously (as opposed to, for example, still images) the function
-may return immediately.</para>
-
- <para>When use of the <function>write()</function> function has
-been negotiated and the driver does not stream yet, the
-<function>poll</function> function starts streaming. When that fails
-it returns a <constant>POLLERR</constant> as above. Otherwise it waits
-until the driver is ready for a non-blocking
-<function>write()</function> call.</para>
-
- <para>If the caller is only interested in events (just
-<constant>POLLPRI</constant> is set in the <structfield>events</structfield>

-
- <para><function>read()</function> attempts to read up to
-<parameter>count</parameter> bytes from file descriptor
-<parameter>fd</parameter> into the buffer starting at
-<parameter>buf</parameter>. The layout of the data in the buffer is
-discussed in the respective device interface section, see ##. If <parameter>count</parameter> is zero,
-<function>read()</function> returns zero and has no other results. If
-<parameter>count</parameter> is greater than
-<constant>SSIZE_MAX</constant>, the result is unspecified. Regardless
-of the <parameter>count</parameter> value each
-<function>read()</function> call will provide at most one frame (two
-fields) worth of data.</para>
-
- <para>By default <function>read()</function> blocks until data
-becomes available. When the <constant>O_NONBLOCK</constant> flag was
-given to the &func-open; function it
-returns immediately with an &EAGAIN; when no data is available. The
-&func-select; or &func-poll; functions
-can always be used to suspend execution until data becomes available. All
-drivers supporting the <function>read()</function> function must also
-support <function>select()</function> and
-<function>poll()</function>.</para>
-
- <para>Drivers can implement read functionality in different
-ways, using a single or multiple buffers and discarding the oldest or
-newest frames once the internal buffers are filled.</para>
-
- <para><function>read()</function> never returns a "snapshot" of a
-buffer being filled. Using a single buffer the driver will stop
-capturing when the application starts reading the buffer until the
-read is finished. Thus only the period of the vertical blanking
-interval is available for reading, or the capture rate must fall below
-the nominal frame rate of the video standard.</para>
-
-<para>The behavior of
-<function>read()</function> when called during the active picture
-period or the vertical blanking separating the top and bottom field
-depends on the discarding policy. A driver discarding the oldest
-frames keeps capturing into an internal buffer, continuously
-overwriting the previously, not read frame, and returns the frame
-being received at the time of the <function>read()</function> call as
-soon as it is complete.</para>
-
- <para>A driver discarding the newest frames stops capturing until
-the next <function>read()</function> call. The frame being received at
-<function>read()</function> time is discarded, returning the following
-frame instead. Again this implies a reduction of the capture rate to
-one half or less of the nominal frame rate. An example of this model
-is the video read mode of the bttv driver, initiating a DMA to user
-memory when <function>read()</function> is called and returning when
-the DMA finished.</para>
-
- <para>In the multiple buffer model drivers maintain a ring of
-internal buffers, automatically advancing to the next free buffer.
-This allows continuous capturing when the application can empty the
-buffers fast enough. Again, the behavior when the driver runs out of
-free buffers depends on the discarding policy.</para>
-
- <para>Applications can get and set the number of buffers used
-internally by the driver with the &VIDIOC-G-PARM; and &VIDIOC-S-PARM;
-ioctls. They are optional, however. The discarding policy is not
-reported and cannot be changed. For minimum requirements see <xref
- linkend="devices" />.</para>

- <title>Return Value</title>
-
- <para>On success, the number of bytes read is returned. It is not
-an error if this number is smaller than the number of bytes requested,
-or the amount of data required for one frame. This may happen for
-example because <function>read()</function> was interrupted by a
-signal. On error, -1 is returned, and the <varname>errno</varname>
-variable is set appropriately. In this case the next read will start
-at the beginning of a new frame. Possible error codes are:</para>

- <title>Input/Output</title>
-
- <para>The V4L2 API defines several different methods to read from or
-write to a device. All drivers exchanging data with applications must
-support at least one of them.</para>
-
- <para>The classic I/O method using the <function>read()</function>
-and <function>write()</function> function is automatically selected
-after opening a V4L2 device. When the driver does not support this
-method attempts to read or write will fail at any time.</para>
-
- <para>Other methods must be negotiated. To select the streaming I/O
-method with memory mapped or user buffers applications call the
-&VIDIOC-REQBUFS; ioctl. The asynchronous I/O method is not defined
-yet.</para>
-
- <para>Video overlay can be considered another I/O method, although
-the application does not directly receive the image data. It is
-selected by initiating video overlay with the &VIDIOC-S-FMT; ioctl.
-For more information see <xref linkend="overlay" />.</para>
-
- <para>Generally exactly one I/O method, including overlay, is
-associated with each file descriptor. The only exceptions are
-applications not exchanging data with a driver ("panel applications",
-see <xref linkend="open" />) and drivers permitting simultaneous video capturing
-and overlay using the same file descriptor, for compatibility with V4L
-and earlier versions of V4L2.</para>
-
- <para><constant>VIDIOC_S_FMT</constant> and
-<constant>VIDIOC_REQBUFS</constant> would permit this to some degree,
-but for simplicity drivers need not support switching the I/O method
-(after first switching away from read/write) other than by closing
-and reopening the device.</para>
-
- <para>The following sections describe the various I/O methods in
-more detail.</para>
-
- <section id="rw">
- <title>Read/Write</title>
-
- <para>Input and output devices support the
-<function>read()</function> and <function>write()</function> function,
-respectively, when the <constant>V4L2_CAP_READWRITE</constant> flag in
-the <structfield>capabilities</structfield> field of &v4l2-capability;
-returned by the &VIDIOC-QUERYCAP; ioctl is set.</para>
-
- <para>Drivers may need the CPU to copy the data, but they may also
-support DMA to or from user memory, so this I/O method is not
-necessarily less efficient than other methods merely exchanging buffer
-pointers. It is considered inferior though because no meta-information
-like frame counters or timestamps are passed. This information is
-necessary to recognize frame dropping and to synchronize with other
-data streams. However this is also the simplest I/O method, requiring
-little or no setup to exchange data. It permits command line stunts
-like this (the <application>vidctrl</application> tool is
-fictitious):</para>

-&gt; dd if=/dev/video of=myimage.422 bs=202752 count=1
-</screen>
- </informalexample>
-
- <para>To read from the device applications use the
-&func-read; function, to write the &func-write; function.
-Drivers must implement one I/O method if they
-exchange data with applications, but it need not be this.<footnote>
- <para>It would be desirable if applications could depend on
-drivers supporting all I/O interfaces, but as much as the complex
-memory mapping I/O can be inadequate for some devices we have no
-reason to require this interface, which is most useful for simple
-applications capturing still images.</para>
- </footnote> When reading or writing is supported, the driver
-must also support the &func-select; and &func-poll;
-function.<footnote>
- <para>At the driver level <function>select()</function> and
-<function>poll()</function> are the same, and
-<function>select()</function> is too important to be optional.</para>

- <title>Streaming I/O (Memory Mapping)</title>
-
- <para>Input and output devices support this I/O method when the
-<constant>V4L2_CAP_STREAMING</constant> flag in the
-<structfield>capabilities</structfield> field of &v4l2-capability;
-returned by the &VIDIOC-QUERYCAP; ioctl is set. There are two
-streaming methods, to determine if the memory mapping flavor is
-supported applications must call the &VIDIOC-REQBUFS; ioctl with the memory type set to <constant>V4L2_MEMORY_MMAP</constant>.</para>
-
- <para>Streaming is an I/O method where only pointers to buffers
-are exchanged between application and driver, the data itself is not
-copied. Memory mapping is primarily intended to map buffers in device
-memory into the application's address space. Device memory can be for
-example the video memory on a graphics card with a video capture
-add-on. However, being the most efficient I/O method available for a
-long time, many other drivers support streaming as well, allocating
-buffers in DMA-able main memory.</para>
-
- <para>A driver can support many sets of buffers. Each set is
-identified by a unique buffer type value. The sets are independent and
-each set can hold a different type of data. To access different sets
-at the same time different file descriptors must be used.<footnote>
- <para>One could use one file descriptor and set the buffer
-type field accordingly when calling &VIDIOC-QBUF; etc., but it makes
-the <function>select()</function> function ambiguous. We also like the
-clean approach of one file descriptor per logical stream. Video
-overlay for example is also a logical stream, although the CPU is not
-needed for continuous operation.</para>
- </footnote></para>
-
- <para>To allocate device buffers applications call the
-&VIDIOC-REQBUFS; ioctl with the desired number of buffers and buffer
-type, for example <constant>V4L2_BUF_TYPE_VIDEO_CAPTURE</constant>.
-This ioctl can also be used to change the number of buffers or to free
-the allocated memory, provided none of the buffers are still
-mapped.</para>
-
- <para>Before applications can access the buffers they must map
-them into their address space with the &func-mmap; function. The
-location of the buffers in device memory can be determined with the
-&VIDIOC-QUERYBUF; ioctl. In the single-planar API case, the
-<structfield>m.offset</structfield> and <structfield>length</structfield>
-returned in a &v4l2-buffer; are passed as sixth and second parameter to the
-<function>mmap()</function> function. When using the multi-planar API,
-&v4l2-buffer; contains an array of &v4l2-plane; structures, each
-containing its own <structfield>m.offset</structfield> and
-<structfield>length</structfield>. When using the multi-planar API, every
-plane of every buffer has to be mapped separately, so the number of
-calls to &func-mmap; should be equal to number of buffers times number of
-planes in each buffer. The offset and length values must not be modified.
-Remember, the buffers are allocated in physical memory, as opposed to virtual
-memory, which can be swapped out to disk. Applications should free the buffers
-as soon as possible with the &func-munmap; function.</para>

- <para>Conceptually streaming drivers maintain two buffer queues, an incoming
-and an outgoing queue. They separate the synchronous capture or output
-operation locked to a video clock from the application which is
-subject to random disk or network delays and preemption by
-other processes, thereby reducing the probability of data loss.
-The queues are organized as FIFOs, buffers will be
-output in the order enqueued in the incoming FIFO, and were
-captured in the order dequeued from the outgoing FIFO.</para>
-
- <para>The driver may require a minimum number of buffers enqueued
-at all times to function, apart of this no limit exists on the number
-of buffers applications can enqueue in advance, or dequeue and
-process. They can also enqueue in a different order than buffers have
-been dequeued, and the driver can <emphasis>fill</emphasis> enqueued
-<emphasis>empty</emphasis> buffers in any order. <footnote>
- <para>Random enqueue order permits applications processing
-images out of order (such as video codecs) to return buffers earlier,
-reducing the probability of data loss. Random fill order allows
-drivers to reuse buffers on a LIFO-basis, taking advantage of caches
-holding scatter-gather lists and the like.</para>
- </footnote> The index number of a buffer (&v4l2-buffer;
-<structfield>index</structfield>) plays no role here, it only
-identifies the buffer.</para>
-
- <para>Initially all mapped buffers are in dequeued state,
-inaccessible by the driver. For capturing applications it is customary
-to first enqueue all mapped buffers, then to start capturing and enter
-the read loop. Here the application waits until a filled buffer can be
-dequeued, and re-enqueues the buffer when the data is no longer
-needed. Output applications fill and enqueue buffers, when enough
-buffers are stacked up the output is started with
-<constant>VIDIOC_STREAMON</constant>. In the write loop, when
-the application runs out of free buffers, it must wait until an empty
-buffer can be dequeued and reused.</para>
-
- <para>To enqueue and dequeue a buffer applications use the
-&VIDIOC-QBUF; and &VIDIOC-DQBUF; ioctl. The status of a buffer being
-mapped, enqueued, full or empty can be determined at any time using the
-&VIDIOC-QUERYBUF; ioctl. Two methods exist to suspend execution of the
-application until one or more buffers can be dequeued. By default
-<constant>VIDIOC_DQBUF</constant> blocks when no buffer is in the
-outgoing queue. When the <constant>O_NONBLOCK</constant> flag was
-given to the &func-open; function, <constant>VIDIOC_DQBUF</constant>
-returns immediately with an &EAGAIN; when no buffer is available. The
-&func-select; or &func-poll; functions are always available.</para>
-
- <para>To start and stop capturing or output applications call the
-&VIDIOC-STREAMON; and &VIDIOC-STREAMOFF; ioctl. Note
-<constant>VIDIOC_STREAMOFF</constant> removes all buffers from both
-queues as a side effect. Since there is no notion of doing anything

- <para>Buffer (plane) addresses and sizes are passed on the fly with the
-&VIDIOC-QBUF; ioctl. Although buffers are commonly cycled,
-applications can pass different addresses and sizes at each
-<constant>VIDIOC_QBUF</constant> call. If required by the hardware the
-driver swaps memory pages within physical memory to create a
-continuous area of memory. This happens transparently to the
-application in the virtual memory subsystem of the kernel. When buffer
-pages have been swapped out to disk they are brought back and finally
-locked in physical memory for DMA.<footnote>
- <para>We expect that frequently used buffers are typically not
-swapped out. Anyway, the process of swapping, locking or generating
-scatter-gather lists may be time consuming. The delay can be masked by
-the depth of the incoming buffer queue, and perhaps by maintaining
-caches assuming a buffer will be soon enqueued again. On the other
-hand, to optimize memory usage drivers can limit the number of buffers
-locked in advance and recycle the most recently used buffers first. Of
-course, the pages of empty buffers in the incoming queue need not be
-saved to disk. Output buffers must be saved on the incoming and
-outgoing queue because an application may share them with other

-
- <para>Filled or displayed buffers are dequeued with the

-time between the completion of the DMA and this ioctl. The memory is
-also unlocked when &VIDIOC-STREAMOFF; is called, &VIDIOC-REQBUFS;, or
-when the device is closed. Applications must take care not to free
-buffers without dequeuing. For once, the buffers remain locked until
-further, wasting physical memory. Second the driver will not be
-notified when the memory is returned to the application's free list
-and subsequently reused for other purposes, possibly completing the
-requested DMA and overwriting valuable data.</para>
-
- <para>For capturing applications it is customary to enqueue a

-
- <para>This I/O method is dedicated to sharing DMA buffers between different
-devices, which may be V4L devices or other video-related devices (e.g. DRM).
-Buffers (planes) are allocated by a driver on behalf of an application. Next,
-these buffers are exported to the application as file descriptors using an API
-which is specific for an allocator driver. Only such file descriptor are
-exchanged. The descriptors and meta-information are passed in &v4l2-buffer; (or
-in &v4l2-plane; in the multi-planar API case). The driver must be switched
-into DMABUF I/O mode by calling the &VIDIOC-REQBUFS; with the desired buffer
-type.</para>

- <para>Captured or displayed buffers are dequeued with the
-&VIDIOC-DQBUF; ioctl. The driver can unlock the buffer at any
-time between the completion of the DMA and this ioctl. The memory is
-also unlocked when &VIDIOC-STREAMOFF; is called, &VIDIOC-REQBUFS;, or
-when the device is closed.</para>
-
- <para>For capturing applications it is customary to enqueue a
-number of empty buffers, to start capturing and enter the read loop.
-Here the application waits until a filled buffer can be dequeued, and
-re-enqueues the buffer when the data is no longer needed. Output
-applications fill and enqueue buffers, when enough buffers are stacked
-up output is started. In the write loop, when the application
-runs out of free buffers it must wait until an empty buffer can be
-dequeued and reused. Two methods exist to suspend execution of the
-application until one or more buffers can be dequeued. By default
-<constant>VIDIOC_DQBUF</constant> blocks when no buffer is in the
-outgoing queue. When the <constant>O_NONBLOCK</constant> flag was
-given to the &func-open; function, <constant>VIDIOC_DQBUF</constant>
-returns immediately with an &EAGAIN; when no buffer is available. The
-&func-select; and &func-poll; functions are always available.</para>
-
- <para>To start and stop capturing or displaying applications call the
-&VIDIOC-STREAMON; and &VIDIOC-STREAMOFF; ioctls. Note that
-<constant>VIDIOC_STREAMOFF</constant> removes all buffers from both queues and
-unlocks all buffers as a side effect. Since there is no notion of doing
-anything "now" on a multitasking system, if an application needs to synchronize
-with another event it should examine the &v4l2-buffer;
-<structfield>timestamp</structfield> of captured or outputted buffers.</para>

- <para>A buffer contains data exchanged by application and

-data is held in planes, while the buffer structure acts as a container
-for the planes. Only pointers to buffers (planes) are exchanged, the data
-itself is not copied. These pointers, together with meta-information like
-timestamps or field parity, are stored in a struct
-<structname>v4l2_buffer</structname>, argument to
-the &VIDIOC-QUERYBUF;, &VIDIOC-QBUF; and &VIDIOC-DQBUF; ioctl.
-In the multi-planar API, some plane-specific members of struct

-plane, are stored in struct <structname>v4l2_plane</structname> instead.
-In that case, struct <structname>v4l2_buffer</structname> contains an array of

- which is used by e.g. on mem-to-mem devices is an exception to the

- <title>Field Order</title>
-
- <para>We have to distinguish between progressive and interlaced
-video. Progressive video transmits all lines of a video image
-sequentially. Interlaced video divides an image into two fields,
-containing only the odd and even lines of the image, respectively.
-Alternating the so called odd and even field are transmitted, and due
-to a small delay between fields a cathode ray TV displays the lines
-interleaved, yielding the original frame. This curious technique was
-invented because at refresh rates similar to film the image would
-fade out too quickly. Transmitting fields reduces the flicker without
-the necessity of doubling the frame rate and with it the bandwidth
-required for each channel.</para>
-
- <para>It is important to understand a video camera does not expose
-one frame at a time, merely transmitting the frames separated into
-fields. The fields are in fact captured at two different instances in
-time. An object on screen may well move between one field and the
-next. For applications analysing motion it is of paramount importance
-to recognize which field of a frame is older, the <emphasis>temporal
-order</emphasis>.</para>
-
- <para>When the driver provides or accepts images field by field
-rather than interleaved, it is also important applications understand
-how the fields combine to frames. We distinguish between top (aka odd) and
-bottom (aka even) fields, the <emphasis>spatial order</emphasis>: The first line
-of the top field is the first line of an interlaced frame, the first
-line of the bottom field is the second line of that frame.</para>
-
- <para>However because fields were captured one after the other,
-arguing whether a frame commences with the top or bottom field is
-pointless. Any two successive top and bottom, or bottom and top fields
-yield a valid frame. Only when the source was progressive to begin
-with, &eg; when transferring film to video, two fields may come from
-the same frame, creating a natural order.</para>
-
- <para>Counter to intuition the top field is not necessarily the
-older field. Whether the older field contains the top or bottom lines
-is a convention determined by the video standard. Hence the
-distinction between temporal and spatial order of fields. The diagrams
-below should make this clearer.</para>
-
- <para>All video capture and output devices must report the current
-field order. Some drivers may permit the selection of a different
-order, to this end applications initialize the
-<structfield>field</structfield> field of &v4l2-pix-format; before
-calling the &VIDIOC-S-FMT; ioctl. If this is not desired it should
-have the value <constant>V4L2_FIELD_ANY</constant> (0).</para>

- <para>Later on libv4lconvert was expanded to also be able to do
-various video processing functions to improve webcam video quality.
-The video processing is split in to 2 parts: libv4lconvert/control and
-libv4lconvert/processing.</para>
-
- <para>The control part is used to offer video controls which can
-be used to control the video processing functions made available by
- libv4lconvert/processing. These controls are stored application wide
-(until reboot) by using a persistent shared memory object.</para>

- <title>libv4l1</title>
- <para>This library offers functions that can be used to quickly
-make v4l1 applications work with v4l2 devices. These functions work exactly
-like the normal open/close/etc, except that libv4l1 does full emulation of
-the v4l1 api on top of v4l2 drivers, in case of v4l1 drivers it
-will just pass calls through.</para>
- <para>Since those functions are emulations of the old V4L1 API,
-it shouldn't be used for new applications.</para>

-applications.</para>
- <para>It provides handles to call V4L2 open/ioctl/close/poll

-the calls in the sense that it will use libv4lconvert to provide more video
-formats and to enhance the image quality.</para>

-<para>The LIRC device interface is a bi-directional interface for

-<para>The lircd userspace daemon reads raw IR data from the LIRC chardev. The

-mode has been selected. lircd obtains supported modes and sets the active mode
-via the ioctl interface, detailed at <xref linkend="lirc_ioctl"/>. The generally

- <para>Media devices increasingly handle multiple related functions. Many USB
- cameras include microphones, video capture hardware can also output video,
- or SoC camera interfaces also perform memory-to-memory operations similar to
- video codecs.</para>
- <para>Independent functions, even when implemented in the same hardware, can
- be modelled as separate devices. A USB camera with a microphone will be
- presented to userspace applications as V4L2 and ALSA capture devices. The
- devices' relationships (when using a webcam, end-users shouldn't have to
- manually select the associated USB microphone), while not made available
- directly to applications by the drivers, can usually be retrieved from
- sysfs.</para>
- <para>With more and more advanced SoC devices being introduced, the current
- approach will not scale. Device topologies are getting increasingly complex
- and can't always be represented by a tree structure. Hardware blocks are
- shared between different functions, creating dependencies between seemingly
- unrelated devices.</para>
- <para>Kernel abstraction APIs such as V4L2 and ALSA provide means for
- applications to access hardware parameters. As newer hardware expose an
- increasingly high number of those parameters, drivers need to guess what
- applications really require based on limited information, thereby
- implementing policies that belong to userspace.</para>

- interfaces, pads and links.</para>

- <para>This is the two-plane versions of the YUV 4:2:0 format where data
-is grouped into 64x32 macroblocks. The three components are separated into two
-sub-images or planes. The Y plane has one byte per pixel and pixels are grouped
-into 64x32 macroblocks. The CbCr plane has the same width, in bytes, as the Y
-plane (and the image), but is half as tall in pixels. The chroma plane is also
-grouped into 64x32 macroblocks.</para>
- <para>Width of the buffer has to be aligned to the multiple of 128, and
-height alignment is 32. Every four adjacent buffers - two horizontally and two
-vertically are grouped together and are located in memory in Z or flipped Z
-order. </para>

- The requirement that width is multiple of 128 is implemented because,
-the Z shape cannot be cut in half horizontally. In case the vertical resolution

- <title>Description</title>
-
- <para>These are two-plane versions of the YUV 4:4:4 format. The three
- components are separated into two sub-images or planes. The Y plane is
- first, with each Y sample stored in one byte per pixel. For
- <constant>V4L2_PIX_FMT_NV24</constant>, a combined CbCr plane
- immediately follows the Y plane in memory. The CbCr plane has the same
- width and height, in pixels, as the Y plane (and the image). Each line
- contains one CbCr pair per pixel, with each Cb and Cr sample stored in
- one byte. <constant>V4L2_PIX_FMT_NV42</constant> is the same except that
- the Cb and Cr samples are swapped, the CrCb plane starts with a Cr
- sample.</para>
-
- <para>If the Y plane has pad bytes after each row, then the CbCr plane
- has twice as many pad bytes after its rows.</para>

- <para>The usage and value of the alpha bits (a) in the ARGB and ABGR formats
- (collectively referred to as alpha formats) depend on the device type and
- hardware operation. <link linkend="capture">Capture</link> devices
- (including capture queues of mem-to-mem devices) fill the alpha component in
- memory. When the device outputs an alpha channel the alpha component will
- have a meaningful value. Otherwise, when the device doesn't output an alpha
- channel but can set the alpha bit to a user-configurable value, the <link
- linkend="v4l2-alpha-component"><constant>V4L2_CID_ALPHA_COMPONENT</constant>
- </link> control is used to specify that alpha value, and the alpha component
- of all pixels will be set to the value specified by that control. Otherwise
- a corresponding format without an alpha component (XRGB or XBGR) must be
- used instead of an alpha format.</para>
-
- <para><link linkend="output">Output</link> devices (including output queues
- of mem-to-mem devices and <link linkend="osd">video output overlay</link>
- devices) read the alpha component from memory. When the device processes the
- alpha channel the alpha component must be filled with meaningful values by
- applications. Otherwise a corresponding format without an alpha component
- (XRGB or XBGR) must be used instead of an alpha format.</para>

- devices and drivers must ignore those bits, for both <link

-
- <para>These four pixel formats are raw sRGB / Bayer formats with
-12 bits per colour. Each colour component is stored in a 16-bit word, with 4
-unused high bits filled with zeros. Each n-pixel row contains n/2 green samples
-and n/2 blue or red samples, with alternating red and blue rows. Bytes are
-stored in memory in little endian order. They are conventionally described
-as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these
-formats</para>

- <title>Standard Image Formats</title>
-
- <para>In order to exchange images between drivers and
-applications, it is necessary to have standard image data formats
-which both sides will interpret the same way. V4L2 includes several
-such formats, and this section is intended to be an unambiguous
-specification of the standard image data formats in V4L2.</para>
-
- <para>V4L2 drivers are not limited to these formats, however.
-Driver-specific formats are possible. In that case the application may
-depend on a codec to convert images to one of the standard formats
-when needed. But the data can still be stored and retrieved in the
-proprietary format. For example, a device may support a proprietary
-compressed format. Applications can still capture and save the data in
-the compressed format, saving much disk space, and later use a codec
-to convert the images to the X Windows screen format when the video is
-to be displayed.</para>
-
- <para>Even so, ultimately, some standard formats are needed, so
-the V4L2 specification would not be complete without well-defined
-standard formats.</para>
-
- <para>The V4L2 standard formats are mainly uncompressed formats. The
-pixels are always arranged in memory from left to right, and from top
-to bottom. The first byte of data in the image buffer is always for
-the leftmost pixel of the topmost row. Following that is the pixel
-immediately to its right, and so on until the end of the top row of
-pixels. Following the rightmost pixel of the row there may be zero or
-more bytes of padding to guarantee that each row of pixel data has a
-certain alignment. Following the pad bytes, if any, is data for the
-leftmost pixel of the second row from the top, and so on. The last row
-has just as many pad bytes after it as the other rows.</para>
-
- <para>In V4L2 each format has an identifier which looks like
-<constant>PIX_FMT_XXX</constant>, defined in the <link
-linkend="videodev">videodev2.h</link> header file. These identifiers
-represent <link linkend="v4l2-fourcc">four character (FourCC) codes</link>
-which are also listed below, however they are not the same as those
-used in the Windows world.</para>
-
- <para>For some formats, data is stored in separate, discontiguous
-memory buffers. Those formats are identified by a separate set of FourCC codes
-and are referred to as "multi-planar formats". For example, a YUV422 frame is
-normally stored in one memory buffer, but it can also be placed in two or three
-separate buffers, with Y component in one buffer and CbCr components in another
-in the 2-planar version or with each component in its own buffer in the
-3-planar case. Those sub-buffers are referred to as "planes".</para>

- <section id="colorspaces">
- <title>Colorspaces</title>
-
- <para>'Color' is a very complex concept and depends on physics, chemistry and
-biology. Just because you have three numbers that describe the 'red', 'green'
-and 'blue' components of the color of a pixel does not mean that you can accurately
-display that color. A colorspace defines what it actually <emphasis>means</emphasis>
-to have an RGB value of e.g. (255,&nbsp;0,&nbsp;0). That is, which color should be
-reproduced on the screen in a perfectly calibrated environment.</para>
-
- <para>In order to do that we first need to have a good definition of
-color, i.e. some way to uniquely and unambiguously define a color so that someone
-else can reproduce it. Human color vision is trichromatic since the human eye has
-color receptors that are sensitive to three different wavelengths of light. Hence
-the need to use three numbers to describe color. Be glad you are not a mantis shrimp
-as those are sensitive to 12 different wavelengths, so instead of RGB we would be
-using the ABCDEFGHIJKL colorspace...</para>
-
- <para>Color exists only in the eye and brain and is the result of how strongly
-color receptors are stimulated. This is based on the Spectral
-Power Distribution (SPD) which is a graph showing the intensity (radiant power)
-of the light at wavelengths covering the visible spectrum as it enters the eye.
-The science of colorimetry is about the relationship between the SPD and color as
-perceived by the human brain.</para>
-
- <para>Since the human eye has only three color receptors it is perfectly
-possible that different SPDs will result in the same stimulation of those receptors
-and are perceived as the same color, even though the SPD of the light is
-different.</para>
-
- <para>In the 1920s experiments were devised to determine the relationship
-between SPDs and the perceived color and that resulted in the CIE 1931 standard
-that defines spectral weighting functions that model the perception of color.
-Specifically that standard defines functions that can take an SPD and calculate
-the stimulus for each color receptor. After some further mathematical transforms
-these stimuli are known as the <emphasis>CIE XYZ tristimulus</emphasis> values
-and these X, Y and Z values describe a color as perceived by a human unambiguously.
-These X, Y and Z values are all in the range [0&hellip;1].</para>
-
- <para>The Y value in the CIE XYZ colorspace corresponds to luminance. Often
-the CIE XYZ colorspace is transformed to the normalized CIE xyY colorspace:</para>
-
- <para>x = X / (X + Y + Z)</para>
- <para>y = Y / (X + Y + Z)</para>
-
- <para>The x and y values are the chromaticity coordinates and can be used to
-define a color without the luminance component Y. It is very confusing to
-have such similar names for these colorspaces. Just be aware that if colors
-are specified with lower case 'x' and 'y', then the CIE xyY colorspace is
-used. Upper case 'X' and 'Y' refer to the CIE XYZ colorspace. Also, y has nothing
-to do with luminance. Together x and y specify a color, and Y the luminance.
-That is really all you need to remember from a practical point of view. At
-the end of this section you will find reading resources that go into much more
-detail if you are interested.
-</para>
-
- <para>A monitor or TV will reproduce colors by emitting light at three
-different wavelengths, the combination of which will stimulate the color receptors
-in the eye and thus cause the perception of color. Historically these wavelengths
-were defined by the red, green and blue phosphors used in the displays. These
-<emphasis>color primaries</emphasis> are part of what defines a colorspace.</para>
-
- <para>Different display devices will have different primaries and some
-primaries are more suitable for some display technologies than others. This has
-resulted in a variety of colorspaces that are used for different display
-technologies or uses. To define a colorspace you need to define the three
-color primaries (these are typically defined as x,&nbsp;y chromaticity coordinates
-from the CIE xyY colorspace) but also the white reference: that is the color obtained
-when all three primaries are at maximum power. This determines the relative power
-or energy of the primaries. This is usually chosen to be close to daylight which has
-been defined as the CIE D65 Illuminant.</para>
-
- <para>To recapitulate: the CIE XYZ colorspace uniquely identifies colors.
-Other colorspaces are defined by three chromaticity coordinates defined in the
-CIE xyY colorspace. Based on those a 3x3 matrix can be constructed that
-transforms CIE XYZ colors to colors in the new colorspace.
-</para>
-
- <para>Both the CIE XYZ and the RGB colorspace that are derived from the
-specific chromaticity primaries are linear colorspaces. But neither the eye,
-nor display technology is linear. Doubling the values of all components in
-the linear colorspace will not be perceived as twice the intensity of the color.
-So each colorspace also defines a transfer function that takes a linear color
-component value and transforms it to the non-linear component value, which is a
-closer match to the non-linear performance of both the eye and displays. Linear
-component values are denoted RGB, non-linear are denoted as R'G'B'. In general
-colors used in graphics are all R'G'B', except in openGL which uses linear RGB.
-Special care should be taken when dealing with openGL to provide linear RGB colors
-or to use the built-in openGL support to apply the inverse transfer function.</para>
-
- <para>The final piece that defines a colorspace is a function that
-transforms non-linear R'G'B' to non-linear Y'CbCr. This function is determined
-by the so-called luma coefficients. There may be multiple possible Y'CbCr
-encodings allowed for the same colorspace. Many encodings of color
-prefer to use luma (Y') and chroma (CbCr) instead of R'G'B'. Since the human
-eye is more sensitive to differences in luminance than in color this encoding
-allows one to reduce the amount of color information compared to the luma
-data. Note that the luma (Y') is unrelated to the Y in the CIE XYZ colorspace.
-Also note that Y'CbCr is often called YCbCr or YUV even though these are
-strictly speaking wrong.</para>
-
- <para>Sometimes people confuse Y'CbCr as being a colorspace. This is not
-correct, it is just an encoding of an R'G'B' color into luma and chroma
-values. The underlying colorspace that is associated with the R'G'B' color
-is also associated with the Y'CbCr color.</para>
-
- <para>The final step is how the RGB, R'G'B' or Y'CbCr values are
-quantized. The CIE XYZ colorspace where X, Y and Z are in the range
-[0&hellip;1] describes all colors that humans can perceive, but the transform to
-another colorspace will produce colors that are outside the [0&hellip;1] range.
-Once clamped to the [0&hellip;1] range those colors can no longer be reproduced
-in that colorspace. This clamping is what reduces the extent or gamut of the
-colorspace. How the range of [0&hellip;1] is translated to integer values in the
-range of [0&hellip;255] (or higher, depending on the color depth) is called the
-quantization. This is <emphasis>not</emphasis> part of the colorspace
-definition. In practice RGB or R'G'B' values are full range, i.e. they
-use the full [0&hellip;255] range. Y'CbCr values on the other hand are limited
-range with Y' using [16&hellip;235] and Cb and Cr using [16&hellip;240].</para>
-
- <para>Unfortunately, in some cases limited range RGB is also used
-where the components use the range [16&hellip;235]. And full range Y'CbCr also exists
-using the [0&hellip;255] range.</para>
-
- <para>In order to correctly interpret a color you need to know the
-quantization range, whether it is R'G'B' or Y'CbCr, the used Y'CbCr encoding
-and the colorspace.
-From that information you can calculate the corresponding CIE XYZ color
-and map that again to whatever colorspace your display device uses.</para>
-
- <para>The colorspace definition itself consists of the three
-chromaticity primaries, the white reference chromaticity, a transfer
-function and the luma coefficients needed to transform R'G'B' to Y'CbCr. While
-some colorspace standards correctly define all four, quite often the colorspace
-standard only defines some, and you have to rely on other standards for
-the missing pieces. The fact that colorspaces are often a mix of different
-standards also led to very confusing naming conventions where the name of
-a standard was used to name a colorspace when in fact that standard was
-part of various other colorspaces as well.</para>
-
- <para>If you want to read more about colors and colorspaces, then the
-following resources are useful: <xref linkend="poynton" /> is a good practical
-book for video engineers, <xref linkend="colimg" /> has a much broader scope and
-describes many more aspects of color (physics, chemistry, biology, etc.).
-The <ulink url="http://www.brucelindbloom.com">http://www.brucelindbloom.com</ulink>
-website is an excellent resource, especially with respect to the mathematics behind
-colorspace conversions. The wikipedia <ulink url="http://en.wikipedia.org/wiki/CIE_1931_color_space#CIE_xy_chromaticity_diagram_and_the_CIE_xyY_color_space">CIE 1931 colorspace</ulink> article

- <title>Defining Colorspaces in V4L2</title>
- <para>In V4L2 colorspaces are defined by four values. The first is the colorspace
-identifier (&v4l2-colorspace;) which defines the chromaticities, the default transfer
-function, the default Y'CbCr encoding and the default quantization method. The second
-is the transfer function identifier (&v4l2-xfer-func;) to specify non-standard
-transfer functions. The third is the Y'CbCr encoding identifier (&v4l2-ycbcr-encoding;)
-to specify non-standard Y'CbCr encodings and the fourth is the quantization identifier
-(&v4l2-quantization;) to specify non-standard quantization methods. Most of the time
-only the colorspace field of &v4l2-pix-format; or &v4l2-pix-format-mplane; needs to
-be filled in. Note that the default R'G'B' quantization is full range for all
-colorspaces except for BT.2020 which uses limited range R'G'B' quantization.</para>

- <title>YUV Formats</title>
-
- <para>YUV is the format native to TV broadcast and composite video
-signals. It separates the brightness information (Y) from the color
-information (U and V or Cb and Cr). The color information consists of
-red and blue <emphasis>color difference</emphasis> signals, this way
-the green component can be reconstructed by subtracting from the
-brightness component. See <xref linkend="colorspaces" /> for conversion
-examples. YUV was chosen because early television would only transmit
-brightness information. To add color in a way compatible with existing
-receivers a new signal carrier was added to transmit the color
-difference signals. Secondary in the YUV format the U and V components
-usually have lower resolution than the Y component. This is an analog
-video compression technique taking advantage of a property of the
-human visual system, being more sensitive to brightness
-information.</para>

- <entry>Two-planar format used by Samsung S5C73MX cameras. The
-first plane contains interleaved JPEG and UYVY image data, followed by meta data
-in form of an array of offsets to the UYVY data blocks. The actual pointer array
-follows immediately the interleaved JPEG/UYVY data, the number of entries in
-this array equals the height of the UYVY image. Each entry is a 4-byte unsigned
-integer in big endian order and it's an offset to a single pixel line of the
-UYVY image. The first plane can start either with JPEG or UYVY data chunk. The
-size of a single UYVY block equals the UYVY image's width multiplied by 2. The
-size of a JPEG chunk depends on the image and can vary with each line.
-<para>The second plane, at an offset of 4084 bytes, contains a 4-byte offset to
-the pointer array in the first plane. This offset is followed by a 4-byte value
-indicating size of the pointer array. All numbers in the second plane are also
-in big endian order. Remaining data in the second plane is undefined. The
-information in the second plane allows to easily find location of the pointer
-array, which can be different for each frame. The size of the pointer array is
-constant for given UYVY image height.</para>
-<para>In order to extract UYVY and JPEG frames an application can initially set
-a data pointer to the start of first plane and then add an offset from the first
-entry of the pointers table. Such a pointer indicates start of an UYVY image
-pixel line. Whole UYVY line can be copied to a separate buffer. These steps
-should be repeated for each line, i.e. the number of entries in the pointer
-array. Anything what's in between the UYVY lines is JPEG data and should be
-concatenated to form the JPEG stream. </para>

-<para>Currently, most analog and digital devices have a Infrared input for remote controllers. Each

-types of controls, depending on the device.</para>
-<para>A Remote Controller interface is mapped as a normal evdev/input interface, just like a keyboard or a mouse.
-So, it uses all ioctls already defined for any other input devices.</para>

-receiver (and/or transmitter) can be used in conjunction with a wide variety of different IR remotes.</para>

-<para>Unfortunately, for several years, there was no effort to create uniform IR keycodes for
-different devices. This caused the same IR keyname to be mapped completely differently on
-different IR devices. This resulted that the same IR keyname to be mapped completely different on
-different IR's. Due to that, V4L2 API now specifies a standard for mapping Media keys on IR.</para>

-<para>Some video capture devices can sample a subsection of a picture and
-shrink or enlarge it to an image of arbitrary size. Next, the devices can
-insert the image into larger one. Some video output devices can crop part of an
-input image, scale it up or down and insert it at an arbitrary scan line and
-horizontal offset into a video signal. We call these abilities cropping,
-scaling and composing.</para>
-
-<para>On a video <emphasis>capture</emphasis> device the source is a video
-signal, and the cropping target determine the area actually sampled. The sink
-is an image stored in a memory buffer. The composing area specifies which part
-of the buffer is actually written to by the hardware. </para>
-
-<para>On a video <emphasis>output</emphasis> device the source is an image in a
-memory buffer, and the cropping target is a part of an image to be shown on a
-display. The sink is the display or the graphics screen. The application may
-select the part of display where the image should be displayed. The size and
-position of such a window is controlled by the compose target.</para>
-
-<para>Rectangles for all cropping and composing targets are defined even if the
-device does supports neither cropping nor composing. Their size and position
-will be fixed in such a case. If the device does not support scaling then the
-cropping and composing rectangles have the same size.</para>

-
-<para>Applications can use the <link linkend="vidioc-g-selection">selection

-default settings and hardware limits.</para>
-
-<para>Video hardware can have various cropping, composing and scaling
-limitations. It may only scale up or down, support only discrete scaling
-factors, or have different scaling abilities in the horizontal and vertical
-directions. Also it may not support scaling at all. At the same time the
-cropping/composing rectangles may have to be aligned, and both the source and
-the sink may have arbitrary upper and lower size limits. Therefore, as usual,
-drivers are expected to adjust the requested parameters and return the actual
-values selected. An application can control the rounding behaviour using <link
-linkend="v4l2-selection-flags"> constraint flags </link>.</para>

- <title>Configuration of video capture</title>
-
-<para>See figure <xref linkend="sel-targets-capture" /> for examples of the
-selection targets available for a video capture device. It is recommended to
-configure the cropping targets before to the composing targets.</para>
-
-<para>The range of coordinates of the top left corner, width and height of
-areas that can be sampled is given by the <constant>V4L2_SEL_TGT_CROP_BOUNDS</constant>
-target. It is recommended for the driver developers to put the
-top/left corner at position <constant>(0,0)</constant>. The rectangle's
-coordinates are expressed in pixels.</para>
-
-<para>The top left corner, width and height of the source rectangle, that is
-the area actually sampled, is given by the <constant>V4L2_SEL_TGT_CROP</constant>
-target. It uses the same coordinate system as <constant>V4L2_SEL_TGT_CROP_BOUNDS</constant>.
-The active cropping area must lie completely inside the capture boundaries. The
-driver may further adjust the requested size and/or position according to hardware
-limitations.</para>
-
-<para>Each capture device has a default source rectangle, given by the
-<constant>V4L2_SEL_TGT_CROP_DEFAULT</constant> target. This rectangle shall
-over what the driver writer considers the complete picture. Drivers shall set
-the active crop rectangle to the default when the driver is first loaded, but
-not later.</para>
-
-<para>The composing targets refer to a memory buffer. The limits of composing
-coordinates are obtained using <constant>V4L2_SEL_TGT_COMPOSE_BOUNDS</constant>.
-All coordinates are expressed in pixels. The rectangle's top/left
-corner must be located at position <constant>(0,0)</constant>. The width and
-height are equal to the image size set by <constant>VIDIOC_S_FMT</constant>.
-</para>
-
-<para>The part of a buffer into which the image is inserted by the hardware is
-controlled by the <constant>V4L2_SEL_TGT_COMPOSE</constant> target.
-The rectangle's coordinates are also expressed in the same coordinate system as

-rectangle. The driver must adjust the composing rectangle to fit to the

-
-<para>For capture devices the default composing rectangle is queried using

- <title>Configuration of video output</title>
-
-<para>For output devices targets and ioctls are used similarly to the video
-capture case. The <emphasis>composing</emphasis> rectangle refers to the
-insertion of an image into a video signal. The cropping rectangles refer to a
-memory buffer. It is recommended to configure the composing targets before to
-the cropping targets.</para>
-
-<para>The cropping targets refer to the memory buffer that contains an image to
-be inserted into a video signal or graphical screen. The limits of cropping
-coordinates are obtained using <constant>V4L2_SEL_TGT_CROP_BOUNDS</constant>.
-All coordinates are expressed in pixels. The top/left corner is always point
-<constant>(0,0)</constant>. The width and height is equal to the image size
-specified using <constant>VIDIOC_S_FMT</constant> ioctl.</para>
-
-<para>The top left corner, width and height of the source rectangle, that is
-the area from which image date are processed by the hardware, is given by the
-<constant>V4L2_SEL_TGT_CROP</constant>. Its coordinates are expressed
-in in the same coordinate system as the bounds rectangle. The active cropping
-area must lie completely inside the crop boundaries and the driver may further
-adjust the requested size and/or position according to hardware
-limitations.</para>
-
-<para>For output devices the default cropping rectangle is queried using
-<constant>V4L2_SEL_TGT_CROP_DEFAULT</constant>. It is usually equal to the
-bounding rectangle.</para>
-
-<para>The part of a video signal or graphics display where the image is
-inserted by the hardware is controlled by <constant>V4L2_SEL_TGT_COMPOSE</constant>
-target. The rectangle's coordinates are expressed in pixels. The composing
-rectangle must lie completely inside the bounds rectangle. The driver must
-adjust the area to fit to the bounding limits. Moreover, the driver can
-perform other adjustments according to hardware limitations.</para>
-
-<para>The device has a default composing rectangle, given by the
-<constant>V4L2_SEL_TGT_COMPOSE_DEFAULT</constant> target. This rectangle shall cover what
-the driver writer considers the complete picture. It is recommended for the
-driver developers to put the top/left corner at position <constant>(0,0)</constant>.
-Drivers shall set the active composing rectangle to the default
-one when the driver is first loaded.</para>
-
-<para>The devices may introduce additional content to video signal other than
-an image from memory buffers. It includes borders around an image. However,
-such a padded area is driver-dependent feature not covered by this document.
-Driver developers are encouraged to keep padded rectangle equal to active one.
-The padded target is accessed by the <constant>V4L2_SEL_TGT_COMPOSE_PADDED</constant>
-identifier. It must contain all pixels from the <constant>V4L2_SEL_TGT_COMPOSE</constant>
-target.</para>

- <title>Scaling control</title>
-
-<para>An application can detect if scaling is performed by comparing the width
-and the height of rectangles obtained using <constant>V4L2_SEL_TGT_CROP</constant>
-and <constant>V4L2_SEL_TGT_COMPOSE</constant> targets. If
-these are not equal then the scaling is applied. The application can compute
-the scaling ratios using these values.</para>

- <title>Comparison with old cropping API</title>
-
-<para>The selection API was introduced to cope with deficiencies of previous
-<link linkend="crop"> API</link>, that was designed to control simple capture
-devices. Later the cropping API was adopted by video output drivers. The ioctls
-are used to select a part of the display were the video signal is inserted. It
-should be considered as an API abuse because the described operation is
-actually the composing. The selection API makes a clear distinction between
-composing and cropping operations by setting the appropriate targets. The V4L2
-API lacks any support for composing to and cropping from an image inside a
-memory buffer. The application could configure a capture device to fill only a
-part of an image by abusing V4L2 API. Cropping a smaller image from a larger
-one is achieved by setting the field
-&v4l2-pix-format;<structfield>::bytesperline</structfield>. Introducing an image offsets
-could be done by modifying field &v4l2-buffer;<structfield>::m_userptr</structfield>
-before calling <constant>VIDIOC_QBUF</constant>. Those
-operations should be avoided because they are not portable (endianness), and do
-not work for macroblock and Bayer formats and mmap buffers. The selection API
-deals with configuration of buffer cropping/composing in a clear, intuitive and
-portable way. Next, with the selection API the concepts of the padded target
-and constraints flags are introduced. Finally, &v4l2-crop; and &v4l2-cropcap;
-have no reserved fields. Therefore there is no way to extend their functionality.
-The new &v4l2-selection; provides a lot of place for future
-extensions. Driver developers are encouraged to implement only selection API.
-The former cropping API would be simulated using the new one.</para>

- <title>Media Bus Pixel Codes</title>
-
- <para>The media bus pixel codes describe image formats as flowing over
- physical busses (both between separate physical components and inside SoC
- devices). This should not be confused with the V4L2 pixel formats that
- describe, using four character codes, image formats as stored in memory.
- </para>
-
- <para>While there is a relationship between image formats on busses and
- image formats in memory (a raw Bayer image won't be magically converted to
- JPEG just by storing it to memory), there is no one-to-one correspondance
- between them.</para>
-
- <section>
- <title>Packed RGB Formats</title>
-
- <para>Those formats transfer pixel data as red, green and blue components.
- The format code is made of the following information.
- <itemizedlist>
- <listitem><para>The red, green and blue components order code, as encoded in a
- pixel sample. Possible values are RGB and BGR.</para></listitem>
- <listitem><para>The number of bits per component, for each component. The values
- can be different for all components. Common values are 555 and 565.</para>
- </listitem>
- <listitem><para>The number of bus samples per pixel. Pixels that are wider than
- the bus width must be transferred in multiple samples. Common values are
- 1 and 2.</para></listitem>
- <listitem><para>The bus width.</para></listitem>
- <listitem><para>For formats where the total number of bits per pixel is smaller
- than the number of bus samples per pixel times the bus width, a padding
- value stating if the bytes are padded in their most high order bits
- (PADHI) or low order bits (PADLO). A "C" prefix is used for component-wise
- padding in the most high order bits (CPADHI) or low order bits (CPADLO)
- of each separate component.</para></listitem>
- <listitem><para>For formats where the number of bus samples per pixel is larger
- than 1, an endianness value stating if the pixel is transferred MSB first
- (BE) or LSB first (LE).</para></listitem>
- </itemizedlist>
- </para>
-
- <para>For instance, a format where pixels are encoded as 5-bits red, 5-bits
- green and 5-bit blue values padded on the high bit, transferred as 2 8-bit
- samples per pixel with the most significant bits (padding, red and half of
- the green value) transferred first will be named

- <para>On LVDS buses, usually each sample is transferred serialized in
- seven time slots per pixel clock, on three (18-bit) or four (24-bit)
- differential data pairs at the same time. The remaining bits are used for
- control signals as defined by SPWG/PSWG/VESA or JEIDA standards.
- The 24-bit RGB format serialized in seven time slots on four lanes using
- JEIDA defined bit mapping will be named
- <constant>MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA</constant>, for example.

- <para>Those formats transfer pixel data as red, green and blue components.
- The format code is made of the following information.
- <itemizedlist>
- <listitem><para>The red, green and blue components order code, as encoded in a
- pixel sample. The possible values are shown in <xref
- linkend="bayer-patterns" />.</para></listitem>
- <listitem><para>The number of bits per pixel component. All components are
- transferred on the same number of bits. Common values are 8, 10 and 12.</para>
- </listitem>
- <listitem><para>The compression (optional). If the pixel components are
- ALAW- or DPCM-compressed, a mention of the compression scheme and the
- number of bits per compressed pixel component.</para></listitem>
- <listitem><para>The number of bus samples per pixel. Pixels that are wider than
- the bus width must be transferred in multiple samples. Common values are
- 1 and 2.</para></listitem>
- <listitem><para>The bus width.</para></listitem>
- <listitem><para>For formats where the total number of bits per pixel is smaller
- than the number of bus samples per pixel times the bus width, a padding
- value stating if the bytes are padded in their most high order bits
- (PADHI) or low order bits (PADLO).</para></listitem>
- <listitem><para>For formats where the number of bus samples per pixel is larger
- than 1, an endianness value stating if the pixel is transferred MSB first
- (BE) or LSB first (LE).</para></listitem>
- </itemizedlist>
- </para>
-
- <para>For instance, a format with uncompressed 10-bit Bayer components
- arranged in a red, green, green, blue pattern transferred as 2 8-bit
- samples per pixel with the least significant bits transferred first will
- be named <constant>MEDIA_BUS_FMT_SRGGB10_2X8_PADHI_LE</constant>.

- <title>Packed YUV Formats</title>
-
- <para>Those data formats transfer pixel data as (possibly downsampled) Y, U
- and V components. Some formats include dummy bits in some of their samples
- and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma) formats.
- One cannot rely on the values of these dummy bits as those are undefined.
- </para>
- <para>The format code is made of the following information.
- <itemizedlist>
- <listitem><para>The Y, U and V components order code, as transferred on the
- bus. Possible values are YUYV, UYVY, YVYU and VYUY for formats with no
- dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC formats.
- </para></listitem>
- <listitem><para>The number of bits per pixel component. All components are
- transferred on the same number of bits. Common values are 8, 10 and 12.</para>
- </listitem>
- <listitem><para>The number of bus samples per pixel. Pixels that are wider than
- the bus width must be transferred in multiple samples. Common values are
- 1, 1.5 (encoded as 1_5) and 2.</para></listitem>
- <listitem><para>The bus width. When the bus width is larger than the number of
- bits per pixel component, several components are packed in a single bus
- sample. The components are ordered as specified by the order code, with
- components on the left of the code transferred in the high order bits.
- Common values are 8 and 16.</para>
- </listitem>
- </itemizedlist>
- </para>
-
- <para>For instance, a format where pixels are encoded as 8-bit YUV values
- downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in the
- U, Y, V, Y order will be named <constant>MEDIA_BUS_FMT_UYVY8_2X8</constant>.
- </para>
-
- <para><xref linkend="v4l2-mbus-pixelcode-yuv8"/> lists existing packed YUV
- formats and describes the organization of each pixel data in each sample.
- When a format pattern is split across multiple samples each of the samples
- in the pattern is described.</para>
-
- <para>The role of each bit transferred over the bus is identified by one
- of the following codes.</para>
-
- <itemizedlist>
- <listitem><para>y<subscript>x</subscript> for luma component bit number x</para></listitem>
- <listitem><para>u<subscript>x</subscript> for blue chroma component bit number x</para></listitem>
- <listitem><para>v<subscript>x</subscript> for red chroma component bit number x</para></listitem>
- <listitem><para>a<subscript>x</subscript> for alpha component bit number x</para></listitem>

-
- <para>This ioctl is used to create buffers for <link linkend="mmap">memory
-mapped</link> or <link linkend="userp">user pointer</link> or <link
-linkend="dmabuf">DMA buffer</link> I/O. It can be used as an alternative or in
-addition to the &VIDIOC-REQBUFS; ioctl, when a tighter
-control over buffers is required. This ioctl can be called multiple times to
-create buffers of different sizes.</para>
-
- <para>To allocate the device buffers applications must initialize the
-relevant fields of the <structname>v4l2_create_buffers</structname> structure.
-The <structfield>count</structfield> field must be set to the number of
-requested buffers, the <structfield>memory</structfield> field specifies the
-requested I/O method and the <structfield>reserved</structfield> array must be
-zeroed.</para>
-
- <para>The <structfield>format</structfield> field specifies the image format
-that the buffers must be able to handle. The application has to fill in this
-&v4l2-format;. Usually this will be done using the &VIDIOC-TRY-FMT; or &VIDIOC-G-FMT; ioctls
-to ensure that the requested format is supported by the driver.
-Based on the format's <structfield>type</structfield> field the requested buffer
-size (for single-planar) or plane sizes (for multi-planar formats) will be
-used for the allocated buffers. The driver may return an error if the size(s)
-are not supported by the hardware (usually because they are too small).</para>
-
- <para>The buffers created by this ioctl will have as minimum size the size
-defined by the <structfield>format.pix.sizeimage</structfield> field (or the
-corresponding fields for other format types). Usually if the
-<structfield>format.pix.sizeimage</structfield> field is less than the minimum
-required for the given format, then an error will be returned since drivers will
-typically not allow this. If it is larger, then the value will be used as-is.
-In other words, the driver may reject the requested size, but if it is accepted
-the driver will use it unchanged.</para>
-
- <para>When the ioctl is called with a pointer to this structure the driver
-will attempt to allocate up to the requested number of buffers and store the
-actual number allocated and the starting index in the
-<structfield>count</structfield> and the <structfield>index</structfield> fields
-respectively. On return <structfield>count</structfield> can be smaller than
-the number requested.</para>

- <para>These ioctls control an audio/video (usually MPEG-) decoder.
-<constant>VIDIOC_DECODER_CMD</constant> sends a command to the
-decoder, <constant>VIDIOC_TRY_DECODER_CMD</constant> can be used to
-try a command without actually executing it. To send a command applications
-must initialize all fields of a &v4l2-decoder-cmd; and call
-<constant>VIDIOC_DECODER_CMD</constant> or <constant>VIDIOC_TRY_DECODER_CMD</constant>
-with a pointer to this structure.</para>
-
- <para>The <structfield>cmd</structfield> field must contain the
-command code. Some commands use the <structfield>flags</structfield> field for
-additional information.
-</para>
-
- <para>A <function>write</function>() or &VIDIOC-STREAMON; call sends an implicit
-START command to the decoder if it has not been started yet.
-</para>
-
- <para>A <function>close</function>() or &VIDIOC-STREAMOFF; call of a streaming
-file descriptor sends an implicit immediate STOP command to the decoder, and all
-buffered data is discarded.</para>
-
- <para>These ioctls are optional, not all drivers may support
-them. They were introduced in Linux 3.3.</para>

-Negative numbers denote reverse playback, so -1000 does reverse playback at normal
-speed. Speeds -1, 0 and 1 have special meanings: speed 0 is shorthand for 1000
-(normal playback). A speed of 1 steps just one frame forward, a speed of -1 steps
-just one frame back.

-<para>This ioctl is an extension to the <link linkend="mmap">memory
-mapping</link> I/O method, therefore it is available only for
-<constant>V4L2_MEMORY_MMAP</constant> buffers. It can be used to export a
-buffer as a DMABUF file at any time after buffers have been allocated with the
-&VIDIOC-REQBUFS; ioctl.</para>
-
-<para> To export a buffer, applications fill &v4l2-exportbuffer;. The
-<structfield>type</structfield> field is set to the same buffer type as was
-previously used with &v4l2-requestbuffers; <structfield>type</structfield>.
-Applications must also set the <structfield>index</structfield> field. Valid
-index numbers range from zero to the number of buffers allocated with
-&VIDIOC-REQBUFS; (&v4l2-requestbuffers; <structfield>count</structfield>)
-minus one. For the multi-planar API, applications set the <structfield>plane</structfield>
-field to the index of the plane to be exported. Valid planes
-range from zero to the maximal number of valid planes for the currently active
-format. For the single-planar API, applications must set <structfield>plane</structfield>
-to zero. Additional flags may be posted in the <structfield>flags</structfield>
-field. Refer to a manual for open() for details.
-Currently only O_CLOEXEC, O_RDONLY, O_WRONLY, and O_RDWR are supported. All
-other fields must be set to zero.
-In the case of multi-planar API, every plane is exported separately using
-multiple <constant>VIDIOC_EXPBUF</constant> calls.</para>
-
-<para>After calling <constant>VIDIOC_EXPBUF</constant> the <structfield>fd</structfield>
-field will be set by a driver. This is a DMABUF file
-descriptor. The application may pass it to other DMABUF-aware devices. Refer to
-<link linkend="dmabuf">DMABUF importing</link> for details about importing
-DMABUF files into V4L2 nodes. It is recommended to close a DMABUF file when it
-is no longer used to allow the associated memory to be reclaimed.</para>

- <entry>V4L2_DV_FL_REDUCED_BLANKING</entry>
- <entry>CVT/GTF specific: the timings use reduced blanking (CVT) or the 'Secondary
-GTF' curve (GTF). In both cases the horizontal and/or vertical blanking
-intervals are reduced, allowing a higher resolution over the same
-bandwidth. This is a read-only flag, applications must not set this.

- </row>
- <row>
- <entry>V4L2_DV_FL_CAN_REDUCE_FPS</entry>
- <entry>CEA-861 specific: set for CEA-861 formats with a framerate that is a multiple
-of six. These formats can be optionally played at 1 / 1.001 speed to
-be compatible with 60 Hz based standards such as NTSC and PAL-M that use a framerate of
-29.97 frames per second. If the transmitter can't generate such frequencies, then the
-flag will also be cleared. This is a read-only flag, applications must not set this.
- </entry>
- </row>
- <row>
- <entry>V4L2_DV_FL_REDUCED_FPS</entry>
- <entry>CEA-861 specific: only valid for video transmitters, the flag is cleared
-by receivers. It is also only valid for formats with the V4L2_DV_FL_CAN_REDUCE_FPS flag
-set, for other formats the flag will be cleared by the driver.
-
-If the application sets this flag, then the pixelclock used to set up the transmitter is
-divided by 1.001 to make it compatible with NTSC framerates. If the transmitter
-can't generate such frequencies, then the flag will also be cleared.
- </entry>
- </row>
- <row>
- <entry>V4L2_DV_FL_HALF_LINE</entry>
- <entry>Specific to interlaced formats: if set, then the vertical frontporch
-of field 1 (aka the odd field) is really one half-line longer and the vertical backporch
-of field 2 (aka the even field) is really one half-line shorter, so each field has exactly
-the same number of half-lines. Whether half-lines can be detected or used depends on
-the hardware.
- </entry>
- </row>
- <row>
- <entry>V4L2_DV_FL_IS_CE_VIDEO</entry>
- <entry>If set, then this is a Consumer Electronics (CE) video format.
-Such formats differ from other formats (commonly called IT formats) in that if
-R'G'B' encoding is used then by default the R'G'B' values use limited range
-(i.e. 16-235) as opposed to full range (i.e. 0-255). All formats defined in CEA-861
-except for the 640x480p59.94 format are CE formats.

- set <structfield>blocks</structfield> to the total number of available EDID blocks
- and it will return 0 without copying any data. This is an easy way to discover how many
- EDID blocks there are. Note that if there are no EDID blocks available at all, then
- the driver will set <structfield>blocks</structfield> to 0 and it returns 0.</para>
-
- <para>To set the EDID blocks of a receiver the application has to fill in the <structfield>pad</structfield>,
- <structfield>blocks</structfield> and <structfield>edid</structfield> fields, set
- <structfield>start_block</structfield> to 0 and zero the <structfield>reserved</structfield> array.
- It is not possible to set part of an EDID,
- it is always all or nothing. Setting the EDID data is only valid for receivers as it makes
- no sense for a transmitter.</para>
-
- <para>The driver assumes that the full EDID is passed in. If there are more EDID blocks than
- the hardware can handle then the EDID is not written, but instead the error code E2BIG is set
- and <structfield>blocks</structfield> is set to the maximum that the hardware supports.
- If <structfield>start_block</structfield> is any
- value other than 0 then the error code EINVAL is set.</para>
-
- <para>To disable an EDID you set <structfield>blocks</structfield> to 0. Depending on the
- hardware this will drive the hotplug pin low and/or block the source from reading the EDID
- data in some way. In any case, the end result is the same: the EDID is no longer available.

- <para>The <constant>VIDIOC_G_ENC_INDEX</constant> ioctl provides
-meta data about a compressed video stream the same or another
-application currently reads from the driver, which is useful for
-random access into the stream without decoding it.</para>
-
- <para>To read the data applications must call
-<constant>VIDIOC_G_ENC_INDEX</constant> with a pointer to a
-&v4l2-enc-idx;. On success the driver fills the
-<structfield>entry</structfield> array, stores the number of elements
-written in the <structfield>entries</structfield> field, and
-initializes the <structfield>entries_cap</structfield> field.</para>
-
- <para>Each element of the <structfield>entry</structfield> array
-contains meta data about one picture. A
-<constant>VIDIOC_G_ENC_INDEX</constant> call reads up to
-<constant>V4L2_ENC_IDX_ENTRIES</constant> entries from a driver
-buffer, which can hold up to <structfield>entries_cap</structfield>
-entries. This number can be lower or higher than
-<constant>V4L2_ENC_IDX_ENTRIES</constant>, but not zero. When the
-application fails to read the meta data in time the oldest entries
-will be lost. When the buffer is empty or no capturing/encoding is in
-progress, <structfield>entries</structfield> will be zero.</para>

- <para>These ioctls allow the caller to get or set multiple
-controls atomically. Control IDs are grouped into control classes (see
-<xref linkend="ctrl-class" />) and all controls in the control array
-must belong to the same control class.</para>
-
- <para>Applications must always fill in the
-<structfield>count</structfield>,
-<structfield>which</structfield>,
-<structfield>controls</structfield> and
-<structfield>reserved</structfield> fields of &v4l2-ext-controls;, and
-initialize the &v4l2-ext-control; array pointed to by the
-<structfield>controls</structfield> fields.</para>
-
- <para>To get the current value of a set of controls applications
-initialize the <structfield>id</structfield>,
-<structfield>size</structfield> and <structfield>reserved2</structfield> fields
-of each &v4l2-ext-control; and call the
-<constant>VIDIOC_G_EXT_CTRLS</constant> ioctl. String controls controls
-must also set the <structfield>string</structfield> field. Controls
-of compound types (<constant>V4L2_CTRL_FLAG_HAS_PAYLOAD</constant> is set)
-must set the <structfield>ptr</structfield> field.</para>
-
- <para>If the <structfield>size</structfield> is too small to
-receive the control result (only relevant for pointer-type controls
-like strings), then the driver will set <structfield>size</structfield>
-to a valid value and return an &ENOSPC;. You should re-allocate the
-memory to this new size and try again. For the string type it is possible that
-the same issue occurs again if the string has grown in the meantime. It is
-recommended to call &VIDIOC-QUERYCTRL; first and use
-<structfield>maximum</structfield>+1 as the new <structfield>size</structfield>
-value. It is guaranteed that that is sufficient memory.
-</para>
-
- <para>N-dimensional arrays are set and retrieved row-by-row. You cannot set a partial
-array, all elements have to be set or retrieved. The total size is calculated
-as <structfield>elems</structfield> * <structfield>elem_size</structfield>.
-These values can be obtained by calling &VIDIOC-QUERY-EXT-CTRL;.</para>
-
- <para>To change the value of a set of controls applications
-initialize the <structfield>id</structfield>, <structfield>size</structfield>,
-<structfield>reserved2</structfield> and
-<structfield>value/value64/string/ptr</structfield> fields of each &v4l2-ext-control; and
-call the <constant>VIDIOC_S_EXT_CTRLS</constant> ioctl. The controls
-will only be set if <emphasis>all</emphasis> control values are
-valid.</para>
-
- <para>To check if a set of controls have correct values applications
-initialize the <structfield>id</structfield>, <structfield>size</structfield>,
-<structfield>reserved2</structfield> and
-<structfield>value/value64/string/ptr</structfield> fields of each &v4l2-ext-control; and
-call the <constant>VIDIOC_TRY_EXT_CTRLS</constant> ioctl. It is up to
-the driver whether wrong values are automatically adjusted to a valid
-value or if an error is returned.</para>
-
- <para>When the <structfield>id</structfield> or
-<structfield>which</structfield> is invalid drivers return an
-&EINVAL;. When the value is out of bounds drivers can choose to take
-the closest valid value or return an &ERANGE;, whatever seems more
-appropriate. In the first case the new value is set in
-&v4l2-ext-control;. If the new control value is inappropriate (e.g. the
-given menu index is not supported by the menu control), then this will
-also result in an &EINVAL; error.</para>
-
- <para>The driver will only set/get these controls if all control
-values are correct. This prevents the situation where only some of the
-controls were set/get. Only low-level errors (&eg; a failed i2c
-command) can still cause this situation.</para>

-
-<para>Before controls are read from/written to hardware a validation step
-takes place: this checks if all controls in the list are valid controls,
-if no attempt is made to write to a read-only control or read from a write-only
-control, and any other up-front checks that can be done without accessing the
-hardware. The exact validations done during this step are driver dependent
-since some checks might require hardware access for some devices, thus making
-it impossible to do those checks up-front. However, drivers should make a
-best-effort to do as many up-front checks as possible.</para>
-
-<para>This check is done to avoid leaving the hardware in an inconsistent state due
-to easy-to-avoid problems. But it leads to another problem: the application needs to
-know whether an error came from the validation step (meaning that the hardware
-was not touched) or from an error during the actual reading from/writing to hardware.</para>
-
-<para>The, in hindsight quite poor, solution for that is to set <structfield>error_idx</structfield>
-to <structfield>count</structfield> if the validation failed. This has the
-unfortunate side-effect that it is not possible to see which control failed the
-validation. If the validation was successful and the error happened while
-accessing the hardware, then <structfield>error_idx</structfield> is less than
-<structfield>count</structfield> and only the controls up to
-<structfield>error_idx-1</structfield> were read or written correctly, and the
-state of the remaining controls is undefined.</para>
-
-<para>Since <constant>VIDIOC_TRY_EXT_CTRLS</constant> does not access hardware
-there is also no need to handle the validation step in this special way,

-
- <para>Applications can use the <constant>VIDIOC_G_FBUF</constant> and
-<constant>VIDIOC_S_FBUF</constant> ioctl to get and set the
-framebuffer parameters for a <link linkend="overlay">Video
-Overlay</link> or <link linkend="osd">Video Output Overlay</link>
-(OSD). The type of overlay is implied by the device type (capture or
-output device) and can be determined with the &VIDIOC-QUERYCAP; ioctl.
-One <filename>/dev/videoN</filename> device must not support both
-kinds of overlay.</para>
-
- <para>The V4L2 API distinguishes destructive and non-destructive
-overlays. A destructive overlay copies captured video images into the
-video memory of a graphics card. A non-destructive overlay blends
-video images into a VGA signal or graphics into a video signal.
-<wordasword>Video Output Overlays</wordasword> are always
-non-destructive.</para>
-
- <para>To get the current parameters applications call the
-<constant>VIDIOC_G_FBUF</constant> ioctl with a pointer to a
-<structname>v4l2_framebuffer</structname> structure. The driver fills
-all fields of the structure or returns an &EINVAL; when overlays are
-not supported.</para>
-
- <para>To set the parameters for a <wordasword>Video Output
-Overlay</wordasword>, applications must initialize the
-<structfield>flags</structfield> field of a struct
-<structname>v4l2_framebuffer</structname>. Since the framebuffer is
-implemented on the TV card all other parameters are determined by the
-driver. When an application calls <constant>VIDIOC_S_FBUF</constant>
-with a pointer to this structure, the driver prepares for the overlay
-and returns the framebuffer parameters as
-<constant>VIDIOC_G_FBUF</constant> does, or it returns an error
-code.</para>
-
- <para>To set the parameters for a <wordasword>non-destructive
-Video Overlay</wordasword>, applications must initialize the
-<structfield>flags</structfield> field, the
-<structfield>fmt</structfield> substructure, and call
-<constant>VIDIOC_S_FBUF</constant>. Again the driver prepares for the
-overlay and returns the framebuffer parameters as
-<constant>VIDIOC_G_FBUF</constant> does, or it returns an error
-code.</para>
-
- <para>For a <wordasword>destructive Video Overlay</wordasword>
-applications must additionally provide a
-<structfield>base</structfield> address. Setting up a DMA to a
-random memory location can jeopardize the system security, its
-stability or even damage the hardware, therefore only the superuser
-can set the parameters for a destructive video overlay.</para>

-
- <para>These ioctls are used to negotiate the format of data
-(typically image format) exchanged between driver and
-application.</para>
-
- <para>To query the current parameters applications set the
-<structfield>type</structfield> field of a struct
-<structname>v4l2_format</structname> to the respective buffer (stream)
-type. For example video capture devices use
-<constant>V4L2_BUF_TYPE_VIDEO_CAPTURE</constant> or
-<constant>V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE</constant>. When the application
-calls the <constant>VIDIOC_G_FMT</constant> ioctl with a pointer to
-this structure the driver fills the respective member of the
-<structfield>fmt</structfield> union. In case of video capture devices
-that is either the &v4l2-pix-format; <structfield>pix</structfield> or
-the &v4l2-pix-format-mplane; <structfield>pix_mp</structfield> member.
-When the requested buffer type is not supported drivers return an
-&EINVAL;.</para>
-
- <para>To change the current format parameters applications
-initialize the <structfield>type</structfield> field and all
-fields of the respective <structfield>fmt</structfield>
-union member. For details see the documentation of the various devices
-types in <xref linkend="devices" />. Good practice is to query the
-current parameters first, and to
-modify only those parameters not suitable for the application. When
-the application calls the <constant>VIDIOC_S_FMT</constant> ioctl
-with a pointer to a <structname>v4l2_format</structname> structure
-the driver checks
-and adjusts the parameters against hardware abilities. Drivers
-should not return an error code unless the <structfield>type</structfield> field is invalid, this is
-a mechanism to fathom device capabilities and to approach parameters
-acceptable for both the application and driver. On success the driver
-may program the hardware, allocate resources and generally prepare for
-data exchange.
-Finally the <constant>VIDIOC_S_FMT</constant> ioctl returns the
-current format parameters as <constant>VIDIOC_G_FMT</constant> does.
-Very simple, inflexible devices may even ignore all input and always
-return the default parameters. However all V4L2 devices exchanging
-data with the application must implement the
-<constant>VIDIOC_G_FMT</constant> and
-<constant>VIDIOC_S_FMT</constant> ioctl. When the requested buffer
-type is not supported drivers return an &EINVAL; on a
-<constant>VIDIOC_S_FMT</constant> attempt. When I/O is already in
-progress or the resource is not available for other reasons drivers
-return the &EBUSY;.</para>
-
- <para>The <constant>VIDIOC_TRY_FMT</constant> ioctl is equivalent
-to <constant>VIDIOC_S_FMT</constant> with one exception: it does not
-change driver state. It can also be called at any time, never
-returning <errorcode>EBUSY</errorcode>. This function is provided to
-negotiate parameters, to learn about hardware limitations, without
-disabling I/O or possibly time consuming hardware preparations.
-Although strongly recommended drivers are not required to implement
-this ioctl.</para>
-
- <para>The format as returned by <constant>VIDIOC_TRY_FMT</constant>
-must be identical to what <constant>VIDIOC_S_FMT</constant> returns for
-the same input or output.</para>

- <para>The hardware may be able to detect the current DV timings
-automatically, similar to sensing the video standard. To do so, applications
-call <constant>VIDIOC_QUERY_DV_TIMINGS</constant> with a pointer to a
-&v4l2-dv-timings;. Once the hardware detects the timings, it will fill in the
-timings structure.</para>
-
-<para>Please note that drivers shall <emphasis>not</emphasis> switch timings automatically
-if new timings are detected. Instead, drivers should send the
-<constant>V4L2_EVENT_SOURCE_CHANGE</constant> event (if they support this) and expect
-that userspace will take action by calling <constant>VIDIOC_QUERY_DV_TIMINGS</constant>.
-The reason is that new timings usually mean different buffer sizes as well, and you
-cannot change buffer sizes on the fly. In general, applications that receive the
-Source Change event will have to call <constant>VIDIOC_QUERY_DV_TIMINGS</constant>,
-and if the detected timings are valid they will have to stop streaming, set the new
-timings, allocate new buffers and start streaming again.</para>
-
-<para>If the timings could not be detected because there was no signal, then
-<errorcode>ENOLINK</errorcode> is returned. If a signal was detected, but
-it was unstable and the receiver could not lock to the signal, then

-but the format is unsupported (e.g. because the pixelclock is out of range
-of the hardware capabilities), then the driver fills in whatever timings it
-could find and returns <errorcode>ERANGE</errorcode>. In that case the application
-can call &VIDIOC-DV-TIMINGS-CAP; to compare the found timings with the hardware's

-(EINVAL cannot be used to skip private controls because it would

-flag can be specified to enumerate all compound controls (i.e. controls
-with type &ge; <constant>V4L2_CTRL_COMPOUND_TYPES</constant> and/or array
-control, in other words controls that contain more than one value).
-Specify both <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> and

-types, and to expose additional control information that cannot be

-

-VIDIOC_QUERYSTD</constant> with a pointer to a &v4l2-std-id; type. The
-driver stores here a set of candidates, this can be a single flag or a
-set of supported standards if for example the hardware can only
-distinguish between 50 and 60 Hz systems. If no signal was detected,
-then the driver will return V4L2_STD_UNKNOWN. When detection is not
-possible or fails, the set must contain all standards supported by the
-current video input or output.</para>

-<para>Please note that drivers shall <emphasis>not</emphasis> switch the video standard

-<para>This ioctl is used to initiate <link linkend="mmap">memory mapped</link>,
-<link linkend="userp">user pointer</link> or <link
-linkend="dmabuf">DMABUF</link> based I/O. Memory mapped buffers are located in
-device memory and must be allocated with this ioctl before they can be mapped
-into the application's address space. User buffers are allocated by
-applications themselves, and this ioctl is merely used to switch the driver
-into user pointer I/O mode and to setup some internal structures.
-Similarly, DMABUF buffers are allocated by applications through a device
-driver, and this ioctl only configures the driver into DMABUF I/O mode without
-performing any direct allocation.</para>
-
- <para>To allocate device buffers applications initialize all fields of the
-<structname>v4l2_requestbuffers</structname> structure. They set the
-<structfield>type</structfield> field to the respective stream or buffer type,
-the <structfield>count</structfield> field to the desired number of buffers,
-<structfield>memory</structfield> must be set to the requested I/O method and
-the <structfield>reserved</structfield> array must be zeroed. When the ioctl is
-called with a pointer to this structure the driver will attempt to allocate the
-requested number of buffers and it stores the actual number allocated in the
-<structfield>count</structfield> field. It can be smaller than the number
-requested, even zero, when the driver runs out of free memory. A larger number
-is also possible when the driver requires more buffers to function correctly.
-For example video output requires at least two buffers, one displayed and one
-filled by the application.</para>
- <para>When the I/O method is not supported the ioctl
-returns an &EINVAL;.</para>
-
- <para>Applications can call <constant>VIDIOC_REQBUFS</constant>
-again to change the number of buffers, however this cannot succeed
-when any buffers are still mapped. A <structfield>count</structfield>
-value of zero frees all buffers, after aborting or finishing any DMA
-in progress, an implicit &VIDIOC-STREAMOFF;. <!-- mhs: I see no
-reason why munmap()ping one or even all buffers must imply
-streamoff.--></para>

- <para>This ioctl allows applications to enumerate all frame sizes
- supported by a sub-device on the given pad for the given media bus format.
- Supported formats can be retrieved with the &VIDIOC-SUBDEV-ENUM-MBUS-CODE;
- ioctl.</para>
-
- <para>To enumerate frame sizes applications initialize the
- <structfield>pad</structfield>, <structfield>which</structfield> ,
- <structfield>code</structfield> and <structfield>index</structfield>
- fields of the &v4l2-subdev-mbus-code-enum; and call the
- <constant>VIDIOC_SUBDEV_ENUM_FRAME_SIZE</constant> ioctl with a pointer to
- the structure. Drivers fill the minimum and maximum frame sizes or return
- an &EINVAL; if one of the input parameters is invalid.</para>
-
- <para>Sub-devices that only support discrete frame sizes (such as most
- sensors) will return one or more frame sizes with identical minimum and
- maximum values.</para>
-
- <para>Not all possible sizes in given [minimum, maximum] ranges need to be
- supported. For instance, a scaler that uses a fixed-point scaling ratio
- might not be able to produce every frame size between the minimum and
- maximum values. Applications must use the &VIDIOC-SUBDEV-S-FMT; ioctl to
- try the sub-device for an exact supported frame size.</para>
-
- <para>Available frame sizes may depend on the current 'try' formats at other
- pads of the sub-device, as well as on the current active links and the
- current values of V4L2 controls. See &VIDIOC-SUBDEV-G-FMT; for more

- <para>These ioctls are used to get and set the frame interval at specific
- subdev pads in the image pipeline. The frame interval only makes sense for
- sub-devices that can control the frame period on their own. This includes,
- for instance, image sensors and TV tuners. Sub-devices that don't support
- frame intervals must not implement these ioctls.</para>
-
- <para>To retrieve the current frame interval applications set the
- <structfield>pad</structfield> field of a &v4l2-subdev-frame-interval; to
- the desired pad number as reported by the media controller API. When they
- call the <constant>VIDIOC_SUBDEV_G_FRAME_INTERVAL</constant> ioctl with a
- pointer to this structure the driver fills the members of the
- <structfield>interval</structfield> field.</para>
-
- <para>To change the current frame interval applications set both the
- <structfield>pad</structfield> field and all members of the
- <structfield>interval</structfield> field. When they call the
- <constant>VIDIOC_SUBDEV_S_FRAME_INTERVAL</constant> ioctl with a pointer to
- this structure the driver verifies the requested interval, adjusts it based
- on the hardware capabilities and configures the device. Upon return the
- &v4l2-subdev-frame-interval; contains the current frame interval as would be
- returned by a <constant>VIDIOC_SUBDEV_G_FRAME_INTERVAL</constant> call.
- </para>
-
- <para>Drivers must not return an error solely because the requested interval
- doesn't match the device capabilities. They must instead modify the interval
- to match what the hardware can provide. The modified interval should be as
- close as possible to the original request.</para>
-
- <para>Sub-devices that support the frame interval ioctls should implement
- them on a single pad only. Their behaviour when supported on multiple pads
- of the same sub-device is not defined.</para>

- <para>This document covers the Linux Kernel to Userspace API's used by
- video and radio streaming devices, including video cameras,
- analog and digital TV receiver cards, AM/FM receiver cards,
- streaming capture and output devices, codec devices and remote
- controllers.</para>

- <para>The media infrastructure API was designed to control such
- devices. It is divided into five parts.</para>
- <para>The first part covers radio, video capture and output,
- cameras, analog TV devices and codecs.</para>
- <para>The second part covers the
- API used for digital TV and Internet reception via one of the
- several digital tv standards. While it is called as DVB API,
- in fact it covers several different video standards including
- DVB-T/T2, DVB-S/S2, DVB-C, ATSC, ISDB-T, ISDB-S,etc. The complete
- list of supported standards can be found at
- <xref linkend="fe-delivery-system-t" />.</para>
- <para>The third part covers the Remote Controller API.</para>
- <para>The fourth part covers the Media Controller API.</para>
- <para>The fifth part covers the CEC (Consumer Electronics Control) API.</para>
- <para>It should also be noted that a media device may also have audio
- components, like mixers, PCM capture, PCM playback, etc, which
- are controlled via ALSA API.</para>
- <para>For additional information and for the latest development code,
- see: <ulink url="https://linuxtv.org">https://linuxtv.org</ulink>.</para>
- <para>For discussing improvements, reporting troubles, sending new drivers, etc, please mail to: <ulink url="http://vger.kernel.org/vger-lists.html#linux-media">Linux Media Mailing List (LMML).</ulink>.</para>
