software scaler filter docs -ssf cgb= chrominance gaussian blur useful for videos with some chroma (color) noise (TV captures, VHS, ...) -ssf lgb= -> luminance gaussian blur hmm, mostly special effect, could be used as lame noise reducer though -ssf chs= -> shift chrominance horizontally -ssf cvs= -> shift chrominance vertically useful if the luma & chroma are not aligned exactly -ssf cs= -> chrominance sharpen -ssf ls= -> luminance sharpen simple sharpening filter note: these will only work if the swscaler is used at all (use -vf scale) example: mplayer foobar.avi -vf scale -ssf lgb=3.0
