From 49e766aa4c3d2d754bc202b87d762b041e50a449 Mon Sep 17 00:00:00 2001 From: Michael Niedermayer Date: Mon, 8 Jun 2020 22:08:37 +0200 Subject: [PATCH] Revert "lavf/mp3dec: don't adjust start time; packets are not adjusted." This causes regressions in end to end timestamps with mp3s and ffmpeg. The revert is to avoid this regression in the 4.3 release See: [FFmpeg-devel] [PATCH] Don't adjust start time for MP3 files; packets are not adjusted.
