Wu Jianhua	4041c1029b	libavfilter/x86/vf_gblur: add localbuf and ff_horiz_slice_avx2/512() 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>	3 years ago
Wu Jianhua	68a2722aee	libavfilter/x86/vf_gblur: add ff_verti_slice_avx2/512() The new vertical slice with AVX2/512 acceleration can significantly improve the performance of Gaussian Filter 2D.

Ruiling Song	83f9da7768	avfilter/vf_gblur: add x86 SIMD optimizations The horizontal pass get ~2x performance with the patch under single thread. Tested overall performance using the command(avx2 enabled): ./ffmpeg -i 1080p.mp4 -vf gblur -f null /dev/null ./ffmpeg -i 1080p.mp4 -vf gblur=threads=1 -f null /dev/null For single thread, the fps improves from 43 to 60, about 40%. For multi-thread, the fps improves from 110 to 130, about 20%. Signed-off-by: Ruiling Song <ruiling.song@intel.com>	6 years ago
