Comment (by PumaD):

 Replying to [comment:12 MasterQuestionable]:
 > ͏    Well, how was the ~ 6.35 MiB sample generated?
 As documented on https://ffmpeg.org/bugreports.html with:
 `dd if=full_video.mp4 of=slightly-damaged-refuses-to-play.mp4 bs=1024
 count=6500`
 > ͏    At very least, try separating the audio/video mere remuxing.
 Remuxing with mkvtoolnix repairs the file enough that the problem is gone.
 Remuxing with ffmpeg bakes the problem into the output such that even
 mkvtoolnix can't repair it anymore.
 > ͏    Also how did you create the ~ 1 GiB sample?
 Same as the other one, just with a target size of 1000 MiB, which is
 luckily enough to cover the spot where the audio goes out.
 `dd if=full_video.mp4 of=slightly-damaged-audio-stops-at-00-43-05.mp4
 bs=1024 count=1024000`
