2014-06-15swr: add prototypes for resample dsp functionsJames Almer
Should fix compilation failures with MSVC and any other compiler without inline asm support. Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

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>

2014-06-02swr: move compensation_distance handling to swri_resample caller.Ronald S. Bultje
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)

delta_frac overflow Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2014-06-02Rewrite main resampling loop (common and linear).Ronald S. Bultje
This removes a branch at a performance-sensitive point (in the middle of the loop). In fate-swr-resample-s32p-8000-2626, this makes the code about 10% faster. It also simplifies the loops, allowing us to rewrite it in yasm at some later point. The compensation_distance != 0 code and index < 0 code are still kind of hairy. For compensation_distance != 0, this should likely be handled in the caller, so that it calls swri_resample twice (once until the dst_incr switch-point, and once with the remainder of the samples). For index < 0, the code should probably be rewritten to break out of the loop once sample_index >= 0, and then resume (e.g. as a tail-call) to the common or linear resampling loops.

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>

These are not supported by all compilers (gcc 2.95 but also older SPARC compilers, see gcc bug #33304 for example), and there is no real need for them. One use of this feature remains in libavdevice/v4l2.c which can't be replaced quite as easily. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>

format max value The constant may change in libavutil but the library may be compiled against an older version, thus rejecting a value which is otherwise supported by the new libavutil. INT_MAX is used here to denote the max allowed value for a sample format. The opt-test code is changed to provide a valid reference example.
