Subject: [FFmpeg-devel] [PATCH] ffmpeg_demux: set default for readrate_catchup to be 5% faster
Date: Wed, 19 Mar 2025 16:36:24 +0530
Message-ID: <20250319110624.1962-1-ffmpeg@gyani.pro> (raw)
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.
Addresses a concern brought up in #11469
