ioppermann has Restreamer been abandoned? It’s strange that no one is checking the bugs.

[ioppermann]

This is indeed a bug and we'll have look at it.

Reastreamer is not abandoned. We had a summer break and are working on other projects that are currently constrain the time for Restreamer.

This has been fixed in the latest release: https://github.com/datarhei/restreamer/releases/tag/v2.12.0
