The biggest "issue" is that 10/12bits data is interpreted as 16bits: - cf. ticket #2966 (that's the remaining missing part) - png can only write 16bits data but sometimes it is not rescaled (image appears darker), cf. the above - ppm images are forcibly rescaled to fill the 16bits (probably lossless but still) etc. > Note that I believe it would be completely wrong to > add additional colourspaces with 8<bpc<16. Yes, on second thought it has its own bag of issues (multiplications of codepaths eg in swscale), but that's to me the only solution that isn't a fragile hack. Also note that there are already plenty of those 8<bpc<16 for planar rgb. -- Christophe _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
