[media] v4l: doc: Remove row numbers from tables
Shorten the tables by removing row numbers in comments, allowing for
later insertion of rows with minimal diffs.

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. - - 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.

This command has two flags: if + ``V4L2_DEC_CMD_STOP_TO_BLACK`` is set, then the decoder will set + the picture to black after it stopped decoding.

Once + the ``V4L2_BUF_FLAG_LAST`` flag was set, the + :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl will not block anymore, + but return an ``EPIPE`` error code. If + ``V4L2_DEC_CMD_STOP_IMMEDIATELY`` is set, then the decoder stops + immediately (ignoring the ``pts`` value), otherwise it will keep + decoding until timestamp >= pts or until the last of the pending + data from its internal buffers was decoded. + * - ``V4L2_DEC_CMD_PAUSE`` + - 2 + - Pause the decoder.

When the decoder has not + been started yet, the driver will return an ``EPERM`` error code. When + the decoder is already running, this command does nothing. No + flags are defined for this command.

This is a read-only flag, + applications must not set this. + * - ``V4L2_DV_FL_CAN_REDUCE_FPS`` + - 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. + * - ``V4L2_DV_FL_REDUCED_FPS`` + - 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. + * - ``V4L2_DV_FL_HALF_LINE`` + - 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. + * - ``V4L2_DV_FL_IS_CE_VIDEO`` + - 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).
