Frei0r is a minimalistic plugin API for video effects. Potential users of this are ffmpeg, mlt, lives, gstreamer and maybe others.
I have sucessfully tested some filter using ffmpeg (built with --enable-frei0r,
see diff below).
For example:
$ ffmpeg -i in.jpg -vf "frei0r=pixeliz0r:0.1:0.1" out.jpg
I didn't manage to get the filters 'facebl0r' and 'facedetect' to work without
crashing (they use opencv), so these are disabled for now.
ffmpeg diff (for testing):
