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