RTMP stream closed with "too many reordered frames" error

[FlyveHest]

Which version are you using?

v1.15.3

Which operating system are you using?

Linux amd64 standard

Describe the issue

I have been running v1.15.0 for a while with 0 issues, and upgraded to v1.15.3 today.

All of a sudden, streams that worked fine before close after a couple of seconds with a "closed: too many reordered frames (11)" error in the log.

I went back to 1.15.0, stream worked fine, then I tried 1.15.1 and 1.15.2, no problems, issue is only present in 1.15.3.

Source stream technical quality is not the best, plenty of warnings when analyzing with ffmpeg, but the visual quality is fine, no artifacts or anything.

Describe how to replicate the issue

1. Upgrade to 1.15.3
2. Watch RTMP stream
3. Stram closes after a few seconds.
