11Format with ΒΌ horizontal chroma resolution, also known as YUV 4:1:1

14Description
15===========
16
17In this format each 12 bytes is eight pixels. In the twelve bytes are
18two CbCr pairs and eight Y's. The first CbCr pair goes with the first
19four Y's, and the second CbCr pair goes with the other four Y's. The Cb
20and Cr components have one fourth the horizontal resolution of the Y
21component.
22
23Do not confuse this format with
24:ref:`V4L2_PIX_FMT_YUV411P <V4L2-PIX-FMT-YUV411P>`. Y41P is derived
25from "YUV 4:1:1 *packed*", while YUV411P stands for "YUV 4:1:1
26*planar*".
