Thank you.
Please allow me another note: I think the naming of this filter
is terrible. I've gone through the list of all ffmpeg filters
many more times than the typical user, but without the specific
pointers I had gotten from you and a few other devs, I would
have never identified the "elbg" filter as something that
would do what I'm looking for.
Given the great results that this algorithm can provide, it's
a bit sad when this filter would remain to be a widely unknown
hidden gem in the future.
No matter whether, 'posterize', 'color_quantize', 'elbg_palettize'
- everything would be better than 'elbg'...
Kind regards,
softworkz
