The conversion script added some comments at the end. They point to the original DocBook files, with will be removed after the manual fixes. So, they'll be pointing to nowere. So, remove those comments. They'll be forever stored at the Kernel tree. So, if someone wants the references, it is just a matter of looking at the backlog.

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).
|
|
|
|
**Byte Order..**
|
|
|
|
Each cell is one byte.
