  23 # 422 is appended to YUV (or YCrCb) if the chroma is sub-sampled by 2
  24 #       horizontally, packed as U Y1 V Y2 (byte order).
  25 # 422HC is appended to YUV (or YCrCb) if the chroma is sub-sampled by 2
  26 #       vertically in addition to horizontally, and is packed the same as
  27 #       422 except that U & V are not valid on the second line.
