Couple reasonably quick requests on this -- could you move the static 
variables in dnr() to the VideoFilter struct for thread safety purposes?  
Also, the average array really should be dynamic -- I'd prefer it not to 
segfault if someone sends in hdtv sized video, for instance..  It also would 
probably make sense to check the incoming frame size and re-allocate the 
buffer if the video size changes (which it can).
