2015-10-26avfilter/vf_removegrain: replace qsort with AV_QSORTGanesh Ajjanagadde
filter_slice calls qsort, so qsort is in a performance critical position. AV_QSORT is substantially faster due to the inlining of the comparison callback. Thus, the increase in performance is worth the increase in binary size. Sample benchmark (x86-64, Haswell, GNU/Linux), filter-removegrain-mode-02 (from FATE) new: 24060 decicycles in qsort, 1 runs, 0 skips 15690 decicycles in qsort, 2 runs, 0 skips 9307 decicycles in qsort, 4 runs, 0 skips 5572 decicycles in qsort, 8 runs, 0 skips 3485 decicycles in qsort, 16 runs, 0 skips 2517 decicycles in qsort, 32 runs, 0 skips 1979 decicycles in qsort, 64 runs, 0 skips 1911 decicycles in qsort, 128 runs, 0 skips 1568 decicycles in qsort, 256 runs, 0 skips 1596 decicycles in qsort, 512 runs, 0 skips 1614 decicycles in qsort, 1024 runs, 0 skips 1874 decicycles in qsort, 2046 runs, 2 skips 2186 decicycles in qsort, 4094 runs, 2 skips old: 246960 decicycles in qsort, 1 runs, 0 skips 135765 decicycles in qsort, 2 runs, 0 skips 70920 decicycles in qsort, 4 runs, 0 skips 37710 decicycles in qsort, 8 runs, 0 skips 20831 decicycles in qsort, 16 runs, 0 skips 12225 decicycles in qsort, 32 runs, 0 skips 8083 decicycles in qsort, 64 runs, 0 skips 6270 decicycles in qsort, 128 runs, 0 skips 5321 decicycles in qsort, 256 runs, 0 skips 4860 decicycles in qsort, 512 runs, 0 skips 4424 decicycles in qsort, 1024 runs, 0 skips 4191 decicycles in qsort, 2046 runs, 2 skips 4934 decicycles in qsort, 4094 runs, 2 skips Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>

2015-10-25avutil/tree: add additional const qualifier to the comparatorGanesh Ajjanagadde
libc's qsort comparator has a const qualifier on both arguments. This adds a missing const qualifier to exactly match the comparator API. Existing usages of av_tree_find, av_tree_insert are appropriately modified: type signature changes of the comparators, and removal of unnecessary void * casts of function pointers.

2015-10-25avfilter/vf_deshake: use a void * comparator for consistencyGanesh Ajjanagadde
For generality, qsort uses a comparator whose elements are void *. This makes the comparator have such a form, and thus makes the void * cast of the comparator pointer useless. Furthermore, this makes the code more consistent with other usages of qsort across the codebase.

2015-10-22avfilter,swresample,swscale: use fabs, fabsf instead of FFABSGanesh Ajjanagadde
It is well known that fabs and fabsf are at least as fast and sometimes faster than the FFABS macro, at least on the gcc+glibc combination. For instance, see the reference: http://patchwork.sourceware.org/patch/6735/. This was a patch to glibc in order to remove their usages of a macro. The reason essentially boils down to fabs using the __builtin_fabs of the compiler, while FFABS needs to infer to not use a branch and to simply change the sign bit. Usually the inference works, but sometimes it does not. This may be easily checked by looking at the asm. This also has the added benefit of reducing macro usage, which has problems with side-effects. Note that avcodec is not handled here, as it is huge and most things there are integer arithmetic anyway. Tested with FATE.

2015-10-14avfilter/all: propagate errors of functions from avfilter/formatsGanesh Ajjanagadde
Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values.

2015-10-08avfilter/delogo: Set default band to 1Jean Delvare
The original interpolation algorithm behaved poorly on the borders and did not even guarantee continuity at the borders. For this reason, a second interpolation/blending pass was required on the borders to make them seamless. However, since the interpolation algorithm was improved in June 2013, the border issues no longer exist. The new algorithm does guarantee continuity at the borders, making the second pass useless. A larger band always increases the cumulated interpolation error. In most cases it also increases the average interpolation error, even though the samples in the band are only partially interpolated. For this reason I would like to get rid of the "band" parameter. As a first step, let's change its default value from 4 to 1 and document it as deprecated. I have benchmarked this change on a combination of input sources and realistic logo areas. Lowering the band value from 4 to 1 resulted in 8 to 39 % less interpolation error per frame (or 1 to 34 % less interpolation error per luma sample.)
