ok, but it will work only if NVxx is used without scaling & stride > 0, u can 
apply it if u want, IMHO it wont break any working stuff

btw, ... yes the swscaler needs some cleanup so that new formats can be added 

level[i]= get_vlc(); i+=get_vlc();		(violates patent EP0266049)
median(mv[y-1][x], mv[y][x-1], mv[y+1][x+1]);	(violates patent #5,905,535)
buf[i]= qp - buf[i-1];				(violates patent #?)

stop it, see http://petition.eurolinux.org & http://petition.ffii.org/eubsa/en
