<para>These formats are designed to match the pixel formats of
|
|
typical PC graphics frame buffers. They occupy 8, 16, 24 or 32 bits
|
|
per pixel. These are all packed-pixel formats, meaning all the data
|
|
for a pixel lie next to each other in memory.</para>
|
|
|
|
<para>When one of these formats is used, drivers shall report the
|
|
colorspace <constant>V4L2_COLORSPACE_SRGB</constant>.</para>
