Description
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.

Proper way to loop gifs is with -loop [some positive number] option for gif muxer.
ffmpeg -i inputBear.gif -loop 8192 x.gif

Nothing to do with gif. This is stream_loop issue with last frame duration.
