Hey Cameron,

Initial research leads to me frei0r
http://ffmpeg.org/libavfilter.html#SEC24

Hope this gets you towards the right direction, it looks like that
libavfilter can connect to the frei0r filter API, so ffmpeg's -vf
frei0r=*effect:parameters
*seems able to perform some more complicated filters.
