    javascript - Does RTCPeerConnection work in Microsoft Edge? - Stack Overflow

    programmeradmin3浏览0评论

    I am currently working on VoIP using WebRTC. It's going to be a UWP application written in JavaScript.

    Now, I am trying to check whether it works or not by testing samples from on Microsoft Edge.

    It turns out that it works fine except RTCPeerConnection.

    For example, when I opened in Edge, it gave me getUserMedia() error: NotFoundError when I clicked the call button. On Chrome, it works fine.

    Another example is when I tried , it gave me 

    Messages:  
Error getting user media: null
getUserMedia error: Failed to get access to local media. Error name was NotFoundError. Continuing without sending a stream.
Create PeerConnection exception: InvalidAccessError

Version:    
gitHash:    c135495bc71e5da61344f098a8209a255f64985f
branch:     master
time:       Fri Apr 8 13:33:05 2016 +0200

    So, how should I fix that? Adapter.js is also called. I also allow everything it needs.

    Or I shouldn't use WebRTC for this project. If so, what should I use?

    Cheers!

    • that looks like an issue with your cam/mic. Check the output of navigator.mediaDevices.enumerateDevices e.g. using this demo – Philipp Hancke Commented Apr 25, 2016 at 5:27

    Reset to default 13

    Microsoft Edge implements ORTC, a more low-level decentralized cousin of WebRTC that does not have an overarching RTCPeerConnection object.

    But the good news is that adapter.js, the official WebRTC polyfill, shims RTCPeerConnection for you on Edge, so you should be able to use WebRTC the same way on all the browsers.

    For instance, this demo works for me in Edge, Firefox and 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 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.oniceconnectionstatechange = e => log(pc1.iceConnectionState);
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" width="160" height="120" autoplay muted></video>
<video id="video2" width="160" height="120" autoplay></video><br>
<div id="div"></div>
<script src="https://webrtc.github.io/adapter/adapter-latest.js"></script>

    You should check your privacy settings first to allow Edge to access your media devices. https://privacy.microsoft./en-us/windows-10-camera-and-privacy
