2014-09-07libswresample: move condition to start of loop.Reimar Döffinger
This avoids several issue like calculating sum/maxcoef incorrectly due to adding up matrix entries that will be overwritten, as well as out-of-range writes to s->matrix if the maximum allowed number of channels is used. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
2014-09-07Remove pointless if.Reimar Döffinger
A branch to avoid some calculation seems unlikely to have any benefits. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
2014-09-07libswresample: Avoid needlessly large on-stack array.Reimar Döffinger
We only actually need to use a tiny part of it. Unfortunately we seem to have no real test coverage on the code, so this is a bit risky. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>

2014-08-04swresample/swresample: Treat mono as planarMichael Niedermayer

2014-07-02Partially revert "swr: add prototypes for resample dsp functions"James Almer
Prototypes are not needed anymore now that the x86 functions don't include resample_template.c The DO_RESAMPLE_ONE macro is removed for that same reason as well. Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

2014-06-28swr: rewrite resample_common/linear_float_sse/avx in yasm.Ronald S. Bultje
Linear interpolation goes from 63 (llvm) or 58 (gcc) to 48 (yasm) cycles/sample on 64bit, or from 66 (llvm/gcc) to 52 (yasm) cycles/ sample on 32bit. Bon-linear goes from 43 (llvm) or 38 (gcc) to 32 (yasm) cycles/sample on 64bit, or from 46 (llvm) or 44 (gcc) to 38 (yasm) cycles/sample on 32bit (all testing on OSX 10.9.2, llvm 5.1 and gcc 4.8/9).

2014-06-14swr: split out DSP functions.Ronald S. Bultje
DSP bits of swri_resample go into their own mini-DSP functions; DSP init goes from a per-call branch in multiple_resample to a proper DSP init routine; x86 bits go into x86/; swri_resample() moves out of resample_template.c into resample.c because it's independent of DSP code or sample type; multiple_resample() is simplified.

2014-06-14swr: remove unnecessary assignment.Ronald S. Bultje
I don't see dst_incr/dst_incr_frac ever being changed from their initial value (which is the inverse of this operation), so it seems to me that this is a no-op. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
