V4L2_PIX_FMT_YUYV
Packed format with ½ horizontal chroma
resolution, also known as YUV 4:2:2

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
