There's this in the output posted above:
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x726024000c80] Sample size 3043950162 is too
large
Is that what you were looking for?

I did not see it, but what does that tell me? I'm but a humble user, I'm
happy when I manage to pass the correct parameters to a CLI.

spec of MP4):
Given that the file is damaged, how much relevance does the spec hold? All
other files in the set play without problems, so my assumption would be
that any problems are the result of corruption. I just reported it because
mkvtoolnix manages to fix it up anyway.

Yes, sound goes out at 00:43:05. 00:44:29 is the total duration of the
sample. It's the largest I could cut it and not be rejected by the upload
page.
