5521b193d6 15/16 bit dithering in C (5% slower, can be disabled by comenting #define DITHER1XBPP out) 
x/yInc bugfix (bug was introduced during the global var removial)
more emms & no messing with ARCH_X86 (=workaround against not cleared mmx state somewhere)
sharpening filter (-ssf cs=<int> & -ssf ls=<int>)

5cebb24be0 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

3885847036 yv12 to yv12 scaler 
someone who knows a bit about vo_odivx could add support for it ...
