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.
