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.
