  11 Format with ¼ horizontal chroma resolution, also known as YUV 4:1:1

  14 Description
  15 ===========
  16
  17 In this format each 12 bytes is eight pixels. In the twelve bytes are
  18 two CbCr pairs and eight Y's. The first CbCr pair goes with the first
  19 four Y's, and the second CbCr pair goes with the other four Y's. The Cb
  20 and Cr components have one fourth the horizontal resolution of the Y
  21 component.
  22
  23 Do not confuse this format with
  24 :ref:`V4L2_PIX_FMT_YUV411P <V4L2-PIX-FMT-YUV411P>`. Y41P is derived
  25 from "YUV 4:1:1 *packed*", while YUV411P stands for "YUV 4:1:1
  26 *planar*".
  27
  28 **Byte Order.**
  29 Each cell is one byte.
