How to handle publisher disconnect?

[terion-name]

Hello! Very neat library, thank you.
But I don't see any possibility to handle when publisher stops streaming.
E.g. I launch ffmpeg -stream_loop -1 -i demo.webm -c:v copy -f rtsp rtsp://127.0.0.1:5554/stream-test and then Cmd+C to stop FFMPEG – and there is no teardown request, so mounts are not cleared, subsequent publishes are not accepted, etc.

This would be not a problem if tcp rtsp_transport would've been supported (BTW any chances for implementing this?), but with UDP streams...

Is there any suggested method?
