From bff7242608409dc52bf2fd51a67bb9d5f171a0ab Mon Sep 17 00:00:00 2001 From: James Darnley Date: Tue, 14 Jul 2015 23:48:47 +0000 Subject: avfilter/vf_removegrain: add x86 and x86_64 SSE2 functions Speed of all modes increased by a factor between 7.4 and 19.8 largely depending on whether bytes are unpacked into words. Modes 2, 3, and 4 have been sped-up by a factor of 43 (thanks quick sort!) All modes are available on x86_64 but only modes 1, 10, 11, 12, 13, 14, 19, 20, 21, and 22 are available on x86 due to the number of SIMD registers used.
