Comment (by daren):

 ffmpeg-static released a couple more versions up to the latest one, can
 somewhat backtrack where this went buggy.

 It happened between releases 4.3.2 and 4.4 and is still an issue with 5.0,
 if someone could try reproduce this with commits that could be the culprit
 here.

 Attaching another script that quickly tries to reproduce this with all the
 ffmpeg-static versions available.
