Question

我找到了video conferencing prototype。但是由于ROAP协议已经被JSEP取代，我无法运行它。

我尝试使用以下来源解决问题：

我认为很多人会很高兴有一个正在运行的JSEP示例。

<script>
  var socket = new WebSocket('ws://mydomain.com:1337');
  var sourcevid = document.getElementById('sourcevid');
  var remotevid = document.getElementById('remotevid');
  var localStream = null;
  var peerConn = null;
  var started = false;

  var logg = function(s) { console.log(s); };

  // when PeerConn is created, send setup data to peer via WebSocket
  function onSignal(message) {
      logg("Sending setup signal");
      socket.send(message);
  }

  // when remote adds a stream, hand it on to the local video element
  function onRemoteStreamAdded(event) {
    logg("Added remote stream");
    remotevid.src = window.webkitURL.createObjectURL(event.stream);
  }

  // when remote removes a stream, remove it from the local video element
  function onRemoteStreamRemoved(event) {
    logg("Remove remote stream");
    remotevid.src = "";
  }

  function createPeerConnection() {
    try {
      logg("Creating peer connection");
      peerConn = new webkitDeprecatedPeerConnection("STUN stun.l.google.com:19302", onSignal);
    } catch (e) {
      try {
        peerConn = new webkitPeerConnection00("STUN stun.l.google.com:19302", onSignal);
      } catch (e) {
        console.log("Failed to create PeerConnection, exception: " + e.message);
      }
    }
    peerConn.addEventListener("addstream", onRemoteStreamAdded, false);
    peerConn.addEventListener("removestream", onRemoteStreamRemoved, false)
  }

  // start the connection upon user request
  function connect() {
    if (!started && localStream) {
      createPeerConnection();
      logg('Adding local stream...');
      peerConn.addStream(localStream);
      started = true;
    } else {
      alert("Local stream not running yet.");
    }
  }

  // accept connection request
  socket.addEventListener("message", onMessage, false);
  function onMessage(evt) {
    logg("RECEIVED: "+evt.data);
    if (!started) {
      createPeerConnection();
      logg('Adding local stream...');
      peerConn.addStream(localStream);
      started = true;
    }
    // Message returned from other side
    logg('Processing signaling message...');
    peerConn.processSignalingMessage(evt.data);
  }

  function hangUp() {
    logg("Hang up.");
    peerConn.close();
    peerConn = null;
    started = false;
  }

  function startVideo() {
      // Replace the source of the video element with the stream from the camera
      try { //try it with spec syntax
        navigator.webkitGetUserMedia({audio: true, video: true}, successCallback, errorCallback);
      } catch (e) {
        navigator.webkitGetUserMedia("video,audio", successCallback, errorCallback);
      }
      function successCallback(stream) {
          sourcevid.src = window.webkitURL.createObjectURL(stream);
          localStream = stream;
      }
      function errorCallback(error) {
          console.error('An error occurred: [CODE ' + error.code + ']');
      }
  }
  function stopVideo() {
    sourcevid.src = "";
  }
  </script>

apprtc.appspot.com的示例显示了使用JSEP的WebRTC。

还有一个ROAP to JSEP library在使用JSEP API时抽象DeprecatedPeerConnection。

在WebRTC演示中集成JSEP
