| V4L2_PIX_FMT_YUYV ('YUYV') |
| ************************** |
| |
| |
| Packed format with ½ horizontal chroma resolution, also known as YUV |
| 4:2:2 |
| |
| |
| Description |
| =========== |
| |
| In this format each four bytes is two pixels. Each four bytes is two |
| Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr |
| belong to both pixels. As you can see, the Cr and Cb components have |
| half the horizontal resolution of the Y component. ``V4L2_PIX_FMT_YUYV`` |
| is known in the Windows environment as YUY2. |
| |
| **Byte Order.** |
| Each cell is one byte. |
