V4L2_PIX_FMT_YUV444M
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 .
