software scaler filter docs

 

-ssf cgb=<float> chrominance gaussian blur

        useful for videos with some chroma (color) noise (TV captures, VHS, ...)

 

-ssf lgb=<float> -> luminance gaussian blur

        hmm, mostly special effect, could be used as lame noise reducer though

 

-ssf chs=<int> -> shift chrominance horizontally

-ssf cvs=<int> -> shift chrominance vertically

        useful if the luma & chroma are not aligned exactly

 

-ssf cs=<float> -> chrominance sharpen

-ssf ls=<float> -> 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
