* swresample/swresample_internal: add av_warn_unused_resultGanesh Ajjanagadde2015-10-15
| | | | | | | This will trigger a few warnings that need to be fixed. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
* swresample: slightly nicer debug output for auto matrixwm42015-10-15
| | | | This is the matrix that will be used for up/downmixing.
* doc/resampler, swresample/options: use proper capitalizationGanesh Ajjanagadde2015-10-10
| | | | | | | | | | | | | | 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. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* swresample/dither: use integer arithmeticGanesh Ajjanagadde2015-08-23
| | | | | | | | 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>
* x86: move XOP emulation code back to x86incJames Almer2015-08-03
| | | | | | | | | | 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>

* swresample: Choose 16bit internally only if input and output is 16bit or lessMichael Niedermayer2015-06-21
| | | | | | | | | | | | | 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.
