From 323cb8c61ea157e01ae98f5a2e3acb8208cfc84a Mon Sep 17 00:00:00 2001 From: Gyan Doshi Date: Wed, 19 Mar 2025 16:25:12 +0530 Subject: [PATCH] ffmpeg_demux: set default for readrate_catchup to be 5% faster The existing default value is the same as the primary readrate. This maintains the flow rate as best as possible but does not reduce the lag. This new value allows catchup to gradually happen without overwhelming the receiver.
