Hi Pierre,
Thank you very much for you answer.

I think what I searching for was (indeed) to write a video filter
module. I assume that there are already existing video filter modules,
and that I can modify one.
Where can I find those modules in the vlc code, and is there a
documentation about how to write/modify one ?
