 Summary of the bug: When using the `apad` filter along with `-shortest`
 flag, the ffmpeg process keeps running without ever finishing.

 How to reproduce:
 {{{

 This workflow works perfectly on version `5.1.4` and `6.0.1`. I looked at
 the changelog, but there are no mentions of `apad` changes, so I figured I
 file a bug report.
