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
James Almer	5750d6c5e9	x86: move XOP emulation code back to x86inc Only two functions that use xop multiply-accumulate instructions where the first operand is the same as the fourth actually took advantage of the macros. This further reduces differences with x264's x86inc. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>	10 years ago

Michael Niedermayer	4977692461	swresample: Choose 16bit internally only if input and output is 16bit or less or if no rematrix and no resampling is performed and the input is 16bit note reampling and rematrix itself always use more than 16bit internally the "internal" sampling format is the format between these steps Its unlikely the difference from this commit is audible in any case unless there is some bug either before or after the change. but multiple people prefer this and it slightly improves the precission of computations.
