I am trying to take snapshots of an RTSP stream on dotnet core running on Ubuntu. I have done this before and didn't have any issues. But, this time the Player_TimeChanged event is never executed and I see this error in the log:
no access_demux modules matched
It's h264 and I can see it's trying to use live555. Here are the logs:

I am not sure what to check. Not sure if the audio error is the culprit. I don't need the audio for this. This code is running in Docker, and I am streaming it from the host machine. Is there an easy way to verify live555 is working correctly? What are some other areas to check?
Any help is appreciated.
