From 63ceb97c0e4c0f23bd79f560bb703b698cf5899e Mon Sep 17 00:00:00 2001 From: Marco Paniconi Date: Thu, 31 Jan 2019 15:19:45 -0800 Subject: [PATCH] vp9: Tune qp_thresh to disable cyclic refresh for screen For screen-content mode, with aq-mode=3: increase the qp thresh for disabling the cyclic refresh. Improves bitrate convergence for content that has been static for long period.
