| # 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. |
