13 <para>These formats are designed to match the pixel formats of
14typical PC graphics frame buffers. They occupy 8, 16, 24 or 32 bits
15per pixel. These are all packed-pixel formats, meaning all the data
16for a pixel lie next to each other in memory.</para>

18 <para>When one of these formats is used, drivers shall report the
19colorspace <constant>V4L2_COLORSPACE_SRGB</constant>.</para>
