Shorten the tables by removing row numbers in comments, allowing for
later insertion of rows with minimal diffs.

V4L2_PIX_FMT_YVU444M
|
|
Planar formats with full horizontal resolution, also known as YUV and
|
|
YVU 4:4:4
|
|
|
|
|
|
Description
|
|
===========
|
|
|
|
This is a multi-planar format, as opposed to a packed format. The three
|
|
components are separated into three sub-images or planes.
|
|
|
|
The Y plane is first. The Y plane has one byte per pixel. For
|
|
``V4L2_PIX_FMT_YUV444M`` the Cb data constitutes the second plane which
|
|
is the same width and height as the Y plane (and as the image). The Cr
|
|
data, just like the Cb plane, is in the third plane.
|
|
|
|
``V4L2_PIX_FMT_YVU444M`` is the same except the Cr data is stored in the
|
|
second plane and the Cb data in the third plane.
|
|
|
|
If the Y plane has pad bytes after each row, then the Cb and Cr planes
|
|
have the same number of pad bytes after their rows.
|
|
|
|
``V4L2_PIX_FMT_YUV444M`` and ``V4L2_PIX_FMT_YUV444M`` are intended to be
|
|
used only in drivers and applications that support the multi-planar API,
|
|
described in :ref:`planar-apis`.
|
|
|
|
**Byte Order.**
|
|
Each cell is one byte.
