 Summary of the bug:
 Trying to turn a MP3 file into a video with a single frame, issue I'm
 facing is that there's a limit to how long the video can be, if it's 553
 seconds long it can be played on MPC-HC with K-lite's codec pack, if it's
 554 seconds long then it can't be played with MPC-HC and can only be
 played on MPV (which I believe uses FFmpeg).

 I have tried a manner of modifications to the image and audio file no no
 avail. Can reproduce it on multiple different files, the 553/554 seconds
 seems to be the only consistent factor.

 How to reproduce:
 {{{
 % ffmpeg -y -i 1.png -i 1.mp3 -c:a copy -t 554 result.mp4
 2021-11-10-git-44c65c6cc0-full_build-www.gyan.dev (also tested on
 ffmpeg-20200807-fab00b0)
