 Summary of the bug:
 For certain moov atom positions, FFmpeg throws errors when input is
 `stdin`, regardless of `async:` prefix usage. For positions further
 downstream, there seems to be an issue.

 How to reproduce:
 {{{
 % cat fail.mp4 | ffmpeg -probesize 8192 -loglevel error -i pipe:0 -f null
 -
 ffmpeg version 7.0.2
 built on 2024-08-03
 }}}

 Errors upon output:
 {{{

 I will attach two files that show the defect (fail.mp4) and that work
 without issue (succeed.mp4)
