2019-06-12avfilter/vf_gblur: add x86 SIMD optimizationsRuiling Song
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>
