From 7af14b37260d4923cdd75c8a19d6a82dad7470c4 Mon Sep 17 00:00:00 2001 From: Ganesh Ajjanagadde Date: Wed, 16 Dec 2015 14:36:53 -0500 Subject: [PATCH] lavfi/vf_colorlevels: replace round by lrint lrint avoids an implicit cast, and is not slower on non-broken libm's. Thus this represents a Pareto improvement.
