Michael Niedermayer	30b2611ed3	swresample: Skip over dither steps if dithering scale is 0 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	946acacdcd	swresample: move dither init up Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Ganesh Ajjanagadde	24e6729a04	swresample/dither: use integer arithmetic This fixes a -Wabsolute-value reported by clang 3.5+ complaining about misuse of fabs() for integer absolute value. An additional benefit is the removal of floating point calculations.
