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.

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