2022-10-27avfilter/vf_threshold: fix handling of zero thresholdPaul B Mahol
2022-06-22avfilter/x86/vf_bwdif: Remove obsolete MMXEXT functionsAndreas Rheinhardt
The only system which benefit from these are truely ancient 32bit x86s as all other systems use at least the SSE2 versions (this includes all x64 cpus (which is why this code is restricted to x86-32)). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

2022-06-22avfilter/x86/vf_eq_init: Remove obsolete MMXEXT functionAndreas Rheinhardt
x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2) for x64. So given that the only systems that benefit from process_mmxext are truely ancient 32bit x86s it is removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

2022-05-06avfilter/af_afir: Only keep DSP stuff in headerAndreas Rheinhardt
Only the AudioFIRDSPContext and the functions for its initialization are needed outside of lavfi/af_afir.c. Also rename the header to af_afirdsp.h to reflect the change. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

2021-10-10avfilter/vf_lut3d: add x86-optimized tetrahedral interpolationMark Reid
I spotted an interesting pattern that I didn't see before that leads to the implementation being faster. The bit shifting table I was using before is no longer needed, and was able to remove quite a few lines.  I also add use of FMA on the AVX2 version. f32 1920x1080 1 thread with prelut c impl 1434012700 UNITS in lut3d->interp,       1 runs,      0 skips 1434035335 UNITS in lut3d->interp,       2 runs,      0 skips 1423615347 UNITS in lut3d->interp,       4 runs,      0 skips 1426268863 UNITS in lut3d->interp,       8 runs,      0 skips sse2 905484420 UNITS in lut3d->interp,       1 runs,      0 skips 905659010 UNITS in lut3d->interp,       2 runs,      0 skips 915167140 UNITS in lut3d->interp,       4 runs,      0 skips 915834222 UNITS in lut3d->interp,       8 runs,      0 skips avx 574794860 UNITS in lut3d->interp,       1 runs,      0 skips 581035090 UNITS in lut3d->interp,       2 runs,      0 skips 584116720 UNITS in lut3d->interp,       4 runs,      0 skips 581460290 UNITS in lut3d->interp,       8 runs,      0 skips avx2 301698880 UNITS in lut3d->interp,       1 runs,      0 skips 301982880 UNITS in lut3d->interp,       2 runs,      0 skips 306962430 UNITS in lut3d->interp,       4 runs,      0 skips 305472025 UNITS in lut3d->interp,       8 runs,      0 skips gbrap16 1920x1080 1 thread with prelut c impl 1480894840 UNITS in lut3d->interp,       1 runs,      0 skips 1502922990 UNITS in lut3d->interp,       2 runs,      0 skips 1496114307 UNITS in lut3d->interp,       4 runs,      0 skips 1492554551 UNITS in lut3d->interp,       8 runs,      0 skips sse2 980777180 UNITS in lut3d->interp,       1 runs,      0 skips 986121520 UNITS in lut3d->interp,       2 runs,      0 skips 986489840 UNITS in lut3d->interp,       4 runs,      0 skips 998832248 UNITS in lut3d->interp,       8 runs,      0 skips avx 622212360 UNITS in lut3d->interp,       1 runs,      0 skips 622981160 UNITS in lut3d->interp,       2 runs,      0 skips 645396315 UNITS in lut3d->interp,       4 runs,      0 skips 641057075 UNITS in lut3d->interp,       8 runs,      0 skips avx2 321336400 UNITS in lut3d->interp,       1 runs,      0 skips 321268920 UNITS in lut3d->interp,       2 runs,      0 skips 323459895 UNITS in lut3d->interp,       4 runs,      0 skips 324949967 UNITS in lut3d->interp,       8 runs,      0 skips

2021-09-18libavfilter/x86/vf_gblur: correct the order of loop stepWu Jianhua
The problem was caused by if the width of the processed block minus 1 is a multiple of the aligned number the instruction jle .bscale_scalar would skip the Optimized Loop Step, which will lead to an incorrect sampling when specifying steps more than 1. Move the Optimized Loop Step after .bscale_scalar to ensure the loop step is enabled. Signed-off-by: Wu Jianhua <jianhua.wu@intel.com>

2021-08-29libavfilter/x86/vf_gblur: add localbuf and ff_horiz_slice_avx2/512()Wu Jianhua
We introduced a ff_horiz_slice_avx2/512() implemented on a new algorithm. In a nutshell, the new algorithm does three things, gathering data from 8/16 rows, blurring data, and scattering data back to the image buffer. Here we used a customized transpose 8x8/16x16 to avoid the huge overhead brought by gather and scatter instructions, which is dependent on the temporary buffer called localbuf added newly. Performance data: ff_horiz_slice_avx2(old): 109.89 ff_horiz_slice_avx2(new): 666.67 ff_horiz_slice_avx512: 1000 Co-authored-by: Cheng Yanfei <yanfei.cheng@intel.com> Co-authored-by: Jin Jun <jun.i.jin@intel.com> Signed-off-by: Wu Jianhua <jianhua.wu@intel.com>
