# YUV is defined to be the same thing as YCrCb (luma and two chroma components).
# 422 is appended to YUV (or YCrCb) if the chroma is sub-sampled by 2
# horizontally, packed as U Y1 V Y2 (byte order).
# 422HC is appended to YUV (or YCrCb) if the chroma is sub-sampled by 2
# vertically in addition to horizontally, and is packed the same as
# 422 except that U & V are not valid on the second line.
