10 | Packed format with ½ horizontal chroma resolution, also known as YUV | |
11 | 4:2:2 | |
12 | ||
13 | ||
14 | Description | |
15 | =========== | |
16 | ||
17 | In this format each four bytes is two pixels. Each four bytes is two | |
18 | Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr | |
19 | belong to both pixels. As you can see, the Cr and Cb components have | |
20 | half the horizontal resolution of the Y component. ``V4L2_PIX_FMT_YUYV`` | |
21 | is known in the Windows environment as YUY2. | |
