Errors when ICE Candidates are received before answer is sent
The solution from Episodex helped me.
First setRemoteDescription, then create own stream, then create and send the answer.
// On read message
if (msg.sdp.type === 'offer') {
this.peerConnection.setRemoteDescription(new RTCSessionDescription(msg.sdp))
.then(() => navigator.mediaDevices.getUserMedia({audio: true, video: true}))
.then(stream => this.peerConnection.addStream(stream));
.then(() => this.peerConnection.createAnswer())
.then(answer => this.peerConnection.setLocalDescription(answer))
.then(() => this.sendMessage({sdp: this.peerConnection.localDescription}))
}
After I wrote this question an answer came into my mind... There is no need for attaching local stream before receiving ICE candidates, but remoteDescription
should be set (which should be done at the moment of receiving offer). In my code I waited with setting remoteDescription
and sending answer until browser gets the local stream.
