| |
| <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> |
