9 Planar formats split luma and chroma data in separate memory regions. They
13   stores the Y components. The second plane is the chroma plane and stores the
21 the chroma planes may be constrained by the line stride of the luma plane.
35 use two planes, and store the luma components in the first plane and the chroma
37 chroma plane, with Cb and Cr always stored in pairs. The chroma order is
41 chroma lines is identical to the padding of the luma lines. Without horizontal
42 subsampling, the chroma line stride (in bytes) is thus equal to twice the luma
43 line stride. With horizontal subsampling by 2, the chroma line stride is equal
