From 83f9da77684e7ea0d8e9f9712ec716424140043a Mon Sep 17 00:00:00 2001 From: Ruiling Song Date: Wed, 15 May 2019 17:54:10 +0800 Subject: 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%.
