+V4L2_PIX_FMT_YUYV ('YUYV')
+**************************
+
+*man V4L2_PIX_FMT_YUYV(2)*
+
+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.
