12 - Semi-planar formats use two planes. The first plane is the luma plane and
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
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
