From 460132c9980f8a1f501a1f69477bca49e1641233 Mon Sep 17 00:00:00 2001 From: Dale Curtis Date: Thu, 23 Apr 2020 16:18:18 -0700 Subject: lavf/mp3dec: don't adjust start time; packets are not adjusted. 7546ac2fee4 made it so that the start_time for mp3 files is adjusted for skip_samples. However, this appears incorrect because subsequent packet timestamps are not adjusted and skip_samples are applied by deleting data from a packet without changing the timestamp. E.g., we are told the start_time is ~25ms and we get a packet with a timestamp of 0 that has had the skip_samples discarded from it. As such rendering engines may incorrectly discard everything prior to the 25ms thinking that is where playback should officially start. Since the samples were deleted without adjusting timestamps though, the true start_time is still 0. Other formats like MP4 with edit lists will adjust both the start time and the timestamps of subsequent packets to avoid this issue.
