From 3d4dd9195f6892b3e9d04dc543d6211095248d22 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sun, 1 Mar 2020 04:56:07 +0100 Subject: avformat/webm_chunk: Avoid unnecessary flushes The webm_chunk muxer caches its output to a dynamic buffer and when it outputs anything, it explicitly flushes it. So set the flags indicating that flushing after each packet should not be done automatically (basically avoiding avio_write_marker() to be called by flush_if_needed() in libavformat/mux.c).
