 Summary of the bug:
 How to reproduce:
 {{{
 % ffmpeg -i input.mp4 output.mp4
 % ffmpeg -i input.mp4 -an -dn -sn output.mp4
 % ffmpeg -i input.mkv output.mkv
 % ffmpeg -i input.mkv -an -dn -sn output.mkv
 }}}
 ffmpeg versions built since approximately 2025-02-02 git master are
 broken;

 `ffmpeg-2025-01-22-git-e20ee9f9ae` works and processes all the file that
 fail above (I have about 40x files that break).

 Log attached shows log from `-report`, the error logs extracted here:
