Comment (by Balling):
420 10 bit video must decode as P010 not P012 or P016. 422 must decode as
P012 and 444 must decode as P016.
You see, 10 bit 420 video works as follows: 10 bit are used for Y plane
and then x2 less bits are used for both Cb and Cr. So together it adds to
10 + 5 = 15 bits. That is P010, that is 16 bits.
