-What: dv1394 (a.k.a. "OHCI-DV I/O support" for FireWire)
-Contact: linux1394-devel@lists.sourceforge.net
-Description:
- New application development should use raw1394 + userspace libraries
- instead, notably libiec61883 which is functionally equivalent.

-Users:
- ffmpeg/libavformat (used by a variety of media players)

+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ /dev/dv1394/* were character device files, one for each FireWire
+ controller and for NTSC and PAL respectively, from which DV data
+ could be received by read() or transmitted by write(). A few
+ ioctl()s allowed limited control.
+ This special-purpose interface has been superseded by libraw1394 +
+ libiec61883 which are functionally equivalent, support HDV, and
+ transparently work on top of the newer firewire kernel drivers.

+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ /dev/raw1394 was a character device file that allowed low-level
+ access to FireWire buses. Its major drawbacks were its inability
+ to implement sensible device security policies, and its low level
+ of abstraction that required userspace clients do duplicate much
+ of the kernel's ieee1394 core functionality.
+ Replaced by /dev/fw*, i.e. the <linux/firewire-cdev.h> ABI of
+ firewire-core.

-What: legacy isochronous ABI of raw1394 (1st generation iso ABI)
-Date: June 2007 (scheduled), removed in kernel v2.6.23
-Contact: linux1394-devel@lists.sourceforge.net
-Description:
- The two request types RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN have
- been deprecated for quite some time. They are very inefficient as they
- come with high interrupt load and several layers of callbacks for each
- packet. Because of these deficiencies, the video1394 and dv1394 drivers
- and the 3rd-generation isochronous ABI in raw1394 (rawiso) were created.
-
-Users:
- libraw1394 users via the long deprecated API raw1394_iso_write,
- raw1394_start_iso_write, raw1394_start_iso_rcv, raw1394_stop_iso_rcv
-
- libdc1394, which optionally uses these old libraw1394 calls
- alternatively to the more efficient video1394 ABI

+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ /dev/video1394/* were character device files, one for each FireWire
+ controller, which were used for isochronous I/O. It was added as an
+ alternative to raw1394's isochronous I/O functionality which had
+ performance issues in its first generation. Any video1394 user had
+ to use raw1394 + libraw1394 too because video1394 did not provide
+ asynchronous I/O for device discovery and configuration.
+ Replaced by /dev/fw*, i.e. the <linux/firewire-cdev.h> ABI of
+ firewire-core.
