Reimar Döffinger	2c5c37ade1	libswresample: move condition to start of loop. 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>	10 years ago
Reimar Döffinger	284123d7fd	Remove pointless if. A branch to avoid some calculation seems unlikely to have any benefits. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
Reimar Döffinger	2231d5b671	libswresample: Avoid needlessly large on-stack array. 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>	10 years ago

James Almer	23a9edf531	Partially revert "swr: add prototypes for resample dsp functions" 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.

Ronald S. Bultje	faa1471ffc	swr: rewrite resample_common/linear_float_sse/avx in yasm. 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).

Ronald S. Bultje	7128a35f8c	swr: split out DSP functions. 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.

Ronald S. Bultje	cdfd9717ed	swr: move compensation_distance handling to swri_resample caller. I think there's an off-by-one in terms of the switchpoint where we switch from dst_incr to ideal_dst_incr, I don't think that's a massive issue, but just be aware of that. It's probably trivial to prevent but I don't care. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> I could not reproduce any off by 1 error, results are bit exact (michael)	11 years ago
