Ice restart

[Gps Test]

What is procedure for restarting ice after one peer loses and regains connection ?

This is in native C++.

My understanding is in connectionchange on failure to call RestartIce() and then resend your offer. Is that correct?

Run pc.restartIce(), catch onnegotiationneeded event, create offer there like below, and send it to the peer.

let offerOpts = {
  iceRestart: true,
  offerToReceiveVideo: true,
  offerToReceiveAudio: true
};

pc.createOffer(offerOpts).then((offer)=>{... send it ... });

Looks like in C++ native, you dont need to set iceRestart to true, that RestartIce() will cause that to happen?

It depends on specific implementation of the signaling protocol. WebRTC does not specify that, and I'm not familiar with Janus.

Try to start from https://github.com/mozilla/janus-plugin-sfu/blob/master/docs/api.md and https://janus.conf.meetecho.com/docs/rest.html

Usually, whole SDP is sent for this purpose.

Assuming you are using the videoroom plugin on Janus then it is documented here:

https://janus.conf.meetecho.com/docs/videoroom

You need to send a 'configure' request with "restart" : true'.

Janus will then send you a new offer at which point you just need to create a new answer and send this back to Janus to commence the ICE restart.
