18V4L2_PIX_FMT_YVU444M
19Planar formats with full horizontal resolution, also known as YUV and
20YVU 4:4:4
21
22
23Description
24===========
25
26This is a multi-planar format, as opposed to a packed format. The three
27components are separated into three sub-images or planes.
28
29The Y plane is first. The Y plane has one byte per pixel. For
30``V4L2_PIX_FMT_YUV444M`` the Cb data constitutes the second plane which
31is the same width and height as the Y plane (and as the image). The Cr
32data, just like the Cb plane, is in the third plane.
33
34``V4L2_PIX_FMT_YVU444M`` is the same except the Cr data is stored in the
35second plane and the Cb data in the third plane.
36
37If the Y plane has pad bytes after each row, then the Cb and Cr planes
38have the same number of pad bytes after their rows.
39
40``V4L2_PIX_FMT_YUV444M`` and ``V4L2_PIX_FMT_YUV444M`` are intended to be
41used only in drivers and applications that support the multi-planar API,
42described in :ref:`planar-apis`.
43
44**Byte Order.**
45Each cell is one byte.
