How to generate an ICE candidate?

I'm developing a video conference with WebRTC in a local network, so I use only one signaling server to exchage SDP data. As I understand, I also need to exchange ICE candidates, but I don't know how to generate them. Thanks.

Solution

  • You can get the generated iceCandidate by setting the peerConnection.onicecandidate event.

    (async () => {
  const pc = new RTCPeerConnection();
  pc.onicecandidate = evt => {
    console.log(evt.candidate?.candidate);
  };
  const stream = await navigator.mediaDevices.getUserMedia({video:true});
  stream.getTracks().forEach(track => pc.addTrack(track, stream));
  const offer = await pc.createOffer();
  await pc.setLocalDescription(offer);
})();
