WebRTC connection between peers connected on localhost 127.0.0.1

[pragnesh patel]

Hello All,

I have slightly different usecase here. I want to do a webrtc connection between two peers running on the same host. My hardware has no connectivity (no WiFi, Ethernet), only interface I have is a lo (127.0.0.1). I am doing signaling using direct function calls between two peer processes.

From peer1 I am able to generate an offer and send it to peer2. peer2 is able to set the remote SDP and I am getting SetSessionDescriptionObserver::OnSuccess() callback, but WebRTC is not generating any ICE candidate on any of the peer. I looked at the configurations but I couldn't find anything matching to my usecase.

Is this a valid usecase, should it work?

One observation is, if I connect my hardware to a WiFi (with/without Internet access), everything works.

Any help is much appreciated.

Thanks,
Pragnesh

Its valid use case. You can see webrtc examples for that. https://webrtc.github.io/samples/
