WebRTC on isolated local network

Question

Hello here.

I am facing a little annoying issue with WebRTC streams on isolated local network (ie no internet at all).
When requesting the stream from the browser, there is a delay of ~20-30 seconds before getting the video. Then everything is perfect, with very low latency.

So I suspect that during the first connection, something is trying to reach an external website (ICE ?) or whatever, but I am not able to figure what.

Do you have any hints or ideas to speedup initial WebRTC negotiation in the MediaMTX settings ?

Thanks !

Can you show us the configuration you're running?

I was going to post my configuration, but during its review, I discovevered that some TURN server were declared. After deletion of this settings, and retry, it works !
So ticket can be closed !

Hi, may I know where is the TURN Server declared? I seems to have this problem too, but my IceServer list is empty.
