Really? It looks fairly well-defined to me, though esoteric (the gamma ramp is basically like sRGB but with a much bigger constant, and the 8-bit Y'CbCr scaling seems unusual): https://en.wikipedia.org/wiki/Photo_CD#Encoding FFmpeg doesn't have a good understanding of gamma (it rarely actually converts between different gamma ramps), but that's not a problem with PhotoCD per se. I can't find a good reason why FFmpeg could not be extended with conversions from the PhotoCD color space to sRGB, at least not if clipping out-of-gamut colors is acceptable. /* Steinar */ -- Homepage: https://www.sesse.net/ _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
