    4 Wait a second why are you applying PhotoYCC equations? I did not attach any PhotoYCC samples. That is YCCK, it is different from PhotoYCC, completly different.

    66As for color management, ffmpeg is already color managed in that part, because the standard does say to convert YCCK to CMYK. Right here, but there is some bug there, I suppose.
