Hello, Patch in attach add support for YUVA444P10 input and alpha 16b encoding
001 : Add frame header description for alpha value (use value close to the official encoder) 002 : indent and add comment, about the header value (based on multimedia wiki doc) 003 : Add support for Prores 444 with alpha 16b The alpha encoding funcs is mainly take with few adaptations from prores_ks except for the get alpha data part (replace with adaptation of subimage_with fill) There is one difference between prores_ks and aw alpha encoding. prores_ks take care about alpha data size, for yuv encoding (in other word reduce quality of yuv data if there is alpha), but it's seems that this is not the case of the official encoder So for prores_aw, i choose to separate yuv encoding and alpha encoding. I only choose to support 16b alpha (not the 8 bit version (and don't plan to add it)) Comments welcome Martin
