Andreas Rheinhardt	790f793844	avutil/common: Don't auto-include mem.h There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	9 months ago
Michael Niedermayer	30b2611ed3	swresample: Skip over dither steps if dithering scale is 0 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Michael Niedermayer	946acacdcd	swresample: move dither init up Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 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. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
