From 2a49d05d1a92cd6454b4e6fc026a66b697c77e67 Mon Sep 17 00:00:00 2001 From: Zhao Zhili Date: Tue, 15 Jul 2025 17:29:32 +0800 Subject: [PATCH] avfilter/vf_vibrance: Update default value of rlum/blum Fix #9195 It looks like vf_vibrance.c is similar to https://github.com/zachsaw/RenderScripts/blob/master/RenderScripts/ImageProcessingShaders/SweetFX/Vibrance.hlsl and https://github.com/kevinlekiller/kwin-effect-shaders_shaders/blob/main/Vibrance.frag Originall written by Christian Cann Schuldt Jensen ~ CeeJay.dk. They use same matrix coeff.
