V4L2_PIX_FMT_YVU410
V4L2_PIX_FMT_YUV410
Planar formats with ¼ horizontal and
vertical chroma resolution, also known as YUV 4:1:0
Description
These are planar formats, 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_YVU410, the Cr plane immediately
follows the Y plane in memory. The Cr plane is ¼ the width and
¼ the height of the Y plane (and of the image). Each Cr belongs
to 16 pixels, a four-by-four square of the image. Following the Cr
plane is the Cb plane, just like the Cr plane.
V4L2_PIX_FMT_YUV410 is the same, except the Cb
plane comes first, then the Cr plane.
If the Y plane has pad bytes after each row, then the Cr
and Cb planes have ¼ as many pad bytes after their rows. In
other words, four Cx rows (including padding) are exactly as long as
one Y row (including padding).
