| 10 | ||
| 11 | Variation of ``V4L2_PIX_FMT_YUYV`` with different order of samples in | |
| 12 | memory | |
| 13 | ||
| 14 | ||
| 15 | Description | |
| 16 | =========== | |
| 17 | ||
| 18 | In this format each four bytes is two pixels. Each four bytes is two | |
| 19 | Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr | |
| 20 | belong to both pixels. As you can see, the Cr and Cb components have | |
| 21 | half the horizontal resolution of the Y component. | |
| 22 | ||

24 | Each cell is one byte. |
