Michael Niedermayer	e16592c42e	swresample/resample: Fix undefined shifts Found-by: Clang -fsanitize=shift Reported-by: Thierry Foucu <tfoucu@google.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	f6bb2cd1b0	swresample/resample: fix invert_initial_buffer() after flush Fixes: asan_heap-uaf_2071250_7_139.ogg Fixes: assertion failure Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
James Almer	857cd1f33b	swr: initialize only the necessary resample dsp functions Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
James Almer	b5f0eac068	swr: rename swresample_dsp init functions to swri_resample_dsp The swresample_ prefix is not for internal functions Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	ddb7b4435a	swr: move dst_size == 0 handling outside DSP function. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	cbf21628a5	swr: remove div/mod from DSP functions. Also fix a bug with resample_compensation resetting dst_incr. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
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.

Michael Niedermayer	4411928c64	swresample/resample: replace assert by av_assert Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	b785c62681	swr: handle initial negative sample index outside DSP function. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	f341340552	swr: handle 64bit overflow check in multiple_resample(). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
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

Michael Niedermayer	5027f39712	swresample/resample: use av_malloc_array() where appropriate Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	f9158b01d0	swresample/resample: Limit filter length Related to CID1197063 The limit choosen is arbitrary and much larger than what makes sense. It avoids the need for checking arithmetic operations with the length for overflow Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
James Almer	32291ba6ea	swresample: add swri_resample_float_sse At least two times faster than the C version. Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
James Almer	7c8bf09edd	swresample: change COMMON_CORE_INT16 asm from SSSE3 to SSE2 pshuf+paddd is slightly faster than phaddd. The real gain is in pre-ssse3 processors like AMD K8 and K10, which get a big boost in performance compared to the mmxext version Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	9078b40d35	swresample: replace 2 av_free() by av_freep() avoids leaving stale pointers in memory Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Alexander Strasser	ac25b31ede	lswr: Improve default resampler's default parameters After making some blind tests on a small collection of music samples for home usage. It turned out that the default cutoff was too low. The impact of filter_size was not clearly distinguishable (the results were on the edge) with the music samples but turned out to be clearly audible in some synthetic samples. Thanks to Daniel for helping out with the listening tests. Signed-off-by: Alexander Strasser <eclipse7@gmx.net>	12 years ago

Clément Bœsch	8f42b09604	swr/resample: fix SSSE3 included unconditionally. 10l Regression since `8ea88339`.	12 years ago
Clément Bœsch	8ea8833979	swr/resample: move templating parameters to template itself. It has various benefits such as allowing some refactoring, clarifying the code in the inclusion part, and making the template understandable in standalone. This commit is based on the templating method used by Justin Ruggles for libavresample.	12 years ago
