| d929fb4e | 22 | /* Frame formats, some of these come from fourcc.org, others are |
| a49d2536 AC |
23 | better explained by video4linux2. The NV11 seems to be described only |
| 24 | on MSDN pages, but even those seem to be gone now. | |
| 25 | Frames can come in many forms, the main categories are RAW, RGB and YUV | |
| 26 | (or YCbCr). The YUV frames come in 4 flavors, determined by how the U and V | |
| 27 | values are subsampled: | |
| 28 | 1. YUV420: hor = 2, ver = 2 | |
| 29 | 2. YUV411: hor = 4, ver = 1 | |
| 30 | 3. YUV422: hor = 2, ver = 1 | |
| 31 | 4. YUV444: hor = 1, ver = 1 | |
| 32 | ||
| 33 | Warning: not all frame formats are supported as input or output to/from ISP. | |
| 34 | Some of these formats are therefore not defined in the output table module. | |
| 35 | Modifications in below frame format enum can require modifications in the | |
| 36 | output table module. | |
| 37 | ||
| 38 | Warning2: Throughout the CSS code assumptions are made on the order | |
| 39 | of formats in this enumeration type, or some sort of copy is maintained. | |
