This is VERY old firmware. Maybe from 2019 year. It's not supported.

This is super old version. I think dev version. You can expect anything.

You need to start with the go2rtc version and stream info.

You can check stream info from go2rtc WebUI

Stream info. And stream probe.

You can use any version you want. If you are sure it is compatible with the new integration version. https://github.com/AlexxIT/WebRTC/blob/121d7558d0a2f1d19452f7b51a6237e048153528/custom_components/webrtc/utils.py#L28

Seems like the reconnection problem when using ffmpeg is pretty common. I think bug in v1.9.3 or v1.9.4

Frigate uses v1.9.2 version

I'll check this when have time.
