javascript - RTCPeerConnection.addIceCandidate() - Uncaught SyntaxError: An invalid or illegal string was specified -

-

the addicecandidate() function giving me error post title, "uncaught syntaxerror: invalid or illegal string specified."

the parameter pass rtcicecandidate object. can print out candidate-attribute result, of them a=candidate:1086438664 2 udp 41754367 41.117.144.193 64564 typ relay raddr 82.146.26.23 rport 58089 generation 0 , on.

this function pass parameter:

function receiveicecandidate(candidate) {     parsecandidate = new rtcicecandidate(json.parse(candidate));     //console.log("parsecandidate.cand = " + parsecandidate.candidate);     remotepc.addicecandidate(parsecandidate);     //remotepc rtcpeerconnection }

before function ever called, remotepc receives sdp offer , sets remotedescription, in following function:

function receiveoffer(offer) {        var ischrome = !!navigator.webkitgetusermedia;     var stun = {     url: ischrome         ? 'stun:stun.l.google.com:19302'         : 'stun:23.21.150.121'     };      var turn = {         url: 'turn:homeo@turn.bistri.com:80',         credential: 'homeo'     };      var iceservers =      {         iceservers: [stun, turn]     };      var sdpconstraints = {     optional: [],     mandatory: {         offertoreceiveaudio: true,         offertoreceivevideo: true         }     };      pc_config = {"iceservers": [{"url": "stun:stun.l.google.com:19302"}]};      remotepc = newpeerconnection(iceservers); // returns peerconnection suitable prefix browser     remotepc.setremotedescription(new rtcsessiondescription(offer.sdp ));         remotepc.createanswer(function(answer)      {          console.log("creating answer.");         remotepc.setlocaldescription(answer);     });      remotepc.onaddstream = function (evt)      {          console.log("on add stream..");         var remote_video = $("#remotevideo");         remote_video.src = createobjecturl(evt.stream);          } }

onaddstream , createanswer never called far - related problem? don't think there's chance answer without icecandidates?
