a few filters (should be removed/merged when arpis videofilter stuff is finished)
-ssf cgb=<float> -> chrominance gaussian blur (nice to improve picture quality) -ssf lgb=<float> -> luminance gaussian blur (dunno what its good for) -ssf chs=<int> -> shift chrominance horizontally -ssf cvs=<int> -> shift chrominance vertically these will only work if the swscaler is used at all Originally committed as revision 4295 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
