2015-10-25all: add const-correctness to qsort comparatorsGanesh Ajjanagadde
This adds const-correctness when needed for the comparators. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
2015-10-22avfilter,swresample,swscale: use fabs, fabsf instead of FFABSGanesh Ajjanagadde
It is well known that fabs and fabsf are at least as fast and sometimes faster than the FFABS macro, at least on the gcc+glibc combination. For instance, see the reference: http://patchwork.sourceware.org/patch/6735/. This was a patch to glibc in order to remove their usages of a macro. The reason essentially boils down to fabs using the __builtin_fabs of the compiler, while FFABS needs to infer to not use a branch and to simply change the sign bit. Usually the inference works, but sometimes it does not. This may be easily checked by looking at the asm. This also has the added benefit of reducing macro usage, which has problems with side-effects. Note that avcodec is not handled here, as it is huge and most things there are integer arithmetic anyway. Tested with FATE.

2015-10-10doc/resampler, swresample/options: use proper capitalizationGanesh Ajjanagadde
Proper names should be capitalized in all user facing API as far as possible. The option names themselves have not been changed since: 1. We consistently keep option names in lower case. 2. Changing them would break existing scripts. 3. I suspect that we want to be similar to Sox and its relevant options. The converse is also true: improper names should not be capitalized generally.

2015-06-21swresample: Choose 16bit internally only if input and output is 16bit or lessMichael Niedermayer
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.
