getTracks()[0].stop()
is constant.
Use getTracks()[0].enabled = false
instead. To disable getTracks()[0].enabled = true
.
This will replace your video with black and your audio will be quiet.
Try it (use https script for Chrome):
var pc1 = new RTCPeerConnection(), pc2 = new RTCPeerConnection(); navigator.mediaDevices.getUserMedia({ video: true, audio: true }) .then(stream => pc1.addStream(video1.srcObject = stream)) .catch(log); var mute = () => video1.srcObject.getTracks().forEach(t => t.enabled = !t.enabled); var add = (pc, can) => can && pc.addIceCandidate(can).catch(log); pc1.onicecandidate = e => add(pc2, e.candidate); pc2.onicecandidate = e => add(pc1, e.candidate); pc2.onaddstream = e => video2.srcObject = e.stream; pc1.onnegotiationneeded = e => pc1.createOffer().then(d => pc1.setLocalDescription(d)) .then(() => pc2.setRemoteDescription(pc1.localDescription)) .then(() => pc2.createAnswer()).then(d => pc2.setLocalDescription(d)) .then(() => pc1.setRemoteDescription(pc2.localDescription)) .catch(log); var log = msg => div.innerHTML += "<br>" + msg;
<video id="video1" height="120" width="160" autoplay muted></video> <video id="video2" height="120" width="160" autoplay></video><br> <input type="checkbox" onclick="mute()">mute</input><div id="div"></div> <script src="https://webrtc.imtqy.com/adapter/adapter-latest.js"></script>
PeerConnections basically stop sending packets in this disconnected state, so it is very efficient.
