* swr: initialize only the necessary resample dsp functionsJames Almer2014-07-04
| | | | | Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* swr: rename swresample_dsp init functions to swri_resample_dspJames Almer2014-07-02
| | | | | | | The swresample_ prefix is not for internal functions Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* swr: move dst_size == 0 handling outside DSP function.Ronald S. Bultje2014-06-28
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* swr: remove div/mod from DSP functions.Ronald S. Bultje2014-06-18
| | | | | | Also fix a bug with resample_compensation resetting dst_incr. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* swr: split out DSP functions.Ronald S. Bultje2014-06-14
| | | | | | | | | | 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.

* swr: move compensation_distance handling to swri_resample caller.Ronald S. Bultje2014-06-02
| | | | | | | | | | | 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)

* swresample/resample: Limit filter lengthMichael Niedermayer2014-04-08
| | | | | | | | | 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>
* swresample: add swri_resample_float_sseJames Almer2014-03-20
| | | | | | | 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>
* swresample: change COMMON_CORE_INT16 asm from SSSE3 to SSE2James Almer2014-03-18
| | | | | | | | | 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>

* lswr: Improve default resampler's default parametersAlexander Strasser2013-01-04
| | | | | | | | | | | | | | 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>

* swr/resample: move templating parameters to template itself.Clément Bœsch2012-11-15
| | | | | | | | | 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.
