New description:
Follow-up to #11005
Got a slightly damaged 1.9 GiB MP4 file. When playing with ffplay (or any
ffmpeg based player like mpv) the video freezes for about half a second at
00:42:58.
Remuxing the file with mkvtoolnix resolves this problem.
(https://gitlab.com/mbunkus/mkvtoolnix; `mkvmerge --output out.mkv
slightly-damaged-audio-stops-at-00-43-05.mp4`)
Remuxing with ffmpeg instead does not.
(`ffmpeg -i slightly-damaged-audio-stops-at-00-43-05.mp4 -c copy out.mkv`)
Sample (from #11028):
https://streams.videolan.org/ffmpeg/incoming/11028/slightly-damaged-audio-
stops-at-00-43-05.mp4 (~ 1 GiB)
Note: NSFW
