Similar to YV12, this format comprises an NxN Y plane followed by (N/2)x(N/2) U and V planes. The U and V planes have the same stride as the Y plane and are restricted to start on 16 line boundaries.
|Y Sample Period||1||1|
|V (Cr) Sample Period||2||2|
|U (Cb) Sample Period||2||2|
Microsoft defines this format as follows:
"The same as YV12, except that the stride of the Cb and Cr planes is the same as the stride in the Y plane. The Cb and Cr planes are also restricted to fall on memory boundaries that are a multiple of 16 lines (a restriction that has no effect on usage for the standard formats, since the standards all use 16×16 macroblocks)."
