**************************
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.
