[FFmpeg-devel] [PATCH] avcodec/ffv1: Support for RGBA64 and GBRAP16

2018-02-01 Thread Jerome Martinez
Add support for 16-bit/component RGB with Alpha encoding and decoding in FFV1, both RGBA64 and GBRAP16 for encoding, GBRAP16 for decoding. Resulting bitstream was tested about lossless encoding/decoding by the compression from DPX to FFV1 then decompression from FFV1 to DPX, see commands
