Dear ffmpeg team,
though i know ffmpeg suppor XYZ color space, i request support for Lab color space.
this is because not only Lab color space includes RGB, YCbCr, and CMYK but also it is designed to approximate the human visual than XYZ. It has an emphasis on perceptual uniformity, L component value is very close to the perception of the human brightness.
this means its effect is produced when filtering a video to make a beautiful RGB or YCbCr video.
for example, when modifying or improve a picture, the use of Lab color space is in general.
i believe this enhances ffmpeg.
