Description
using the latest ffmpeg, it seems eq filter doesnt properly desaturate, output contains colors towards green spectrum like #0e100d
ffmpeg -filter_complex rgbtestsrc,eq=saturation=0 -frames:v 1 -y out-eq.png
hue filter seems to do the job properly (i.e. #050505)
ffmpeg -filter_complex rgbtestsrc,hue=s=0 -frames:v 1 -y out-hue.png
