audio only communication

Hi Oney,

I’m trying to get audio only communication to work and having no lucks now. Since every examples are all video based, my question is:

• should audio-only rendering use RTCView or use some components like react-native-audio?
• if mediaConstraints={"audio": true, "video": false} then it should not include video related ice info in sdp right?

If it needs to do some PR, please shed some light on it, i’d like to do that. Thanks for the great job.

Yes, it support audio-only. You can just use PeerConnection and don’t set stream’s URL to a RTCView

Hi. Sorry because I have the same issue and the resolution still not work for me. I’m trying to find a way to play media got from the peerConnection.onaddstream. Currently, its callback got a stream after I send invite but I still can’t hear any stream media

My peer.onaddstream handler

peer.onaddstream = function(event) {
     var remoteStream = event.stream;
     setStream(remoteStream.toURL());
};

The setStream will change state of RTCView’s streamURL props. I already tried to remove it but still not work
