From 49054fe94c2f36881f63d15eca6e4bfb7f71b8ce Mon Sep 17 00:00:00 2001 From: Limin Wang Date: Wed, 1 Jul 2020 20:57:58 +0800 Subject: [PATCH] FATE: fix colorbalance fate test failed on x86_32 floating point precision will cause rgb*max generate different value on x86_32 and x86_64. have pass fate test on x86_32 and x86_64 by using lrintf to get the nearest integral value for rgb * max before av_clip.
