I can't seem to get ffmpeg's lutrgb to perform addition.
This code doesn't work as expected:
But this code performs as predicted:Code:-vf lutrgb=r='val+32'
What am I doing wrong? Is it possible that lutrgb can multiply but not add?Code:-vf lutrgb=r='val*0.5'

try putting them in quotes
This works too
Maybe something else in your commandline causing a problem ?
