[vlc-devel] [PATCH] adding posterize video filter

[Branko Kokanovic]

Hi,
I implemented posterize filter (in attachment). It works with planar and
packed YUV and RGB24/32 formats. Output is the same as Gimp's
"Posterize" functionality. I wrote one filter before[1], but this one
should also go to a review. Only thing I'm not satisfied with is that I
implemented my own functions for RGB<->YUV conversion, but since I asked
here that before[2] and no one replied, I didn't had much choice.
Thanks in advance for reviewing/applying to master.

Greetings, Branko Kokanovic
