 Summary of the bug:
 Some gifs that are looped with `-stream_loop` cause animations to play
 incorrectly. I'm not sure about the cause but at first glance it could be
 due to incorrect delay between frames.

 How to reproduce:
 {{{
 % ffmpeg -v 9 -loglevel 99 -report -stream_loop 3 -i inputBear.gif
 outputWithJitter.gif

 ffmpeg version 4.3.1, used the pre-build binary and tested on mac
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
