+
+Variation of ``V4L2_PIX_FMT_YUYV`` with different order of samples in
+memory
+
+
+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.
+
+**Byte Order.**
+Each cell is one byte.
