Internet Explorer hangs while using Temasys plugin

[vinayakkedge]

I am using adapter.js of Temasys alongwith signalling server of node js.

Everything works just fine with Chrome and Firefox.

But same application video calling getting hanged in IE.

Am I missing something? Any help in this regard will be most appreciable.

Thanks and regards,

Hi,
I'm going to need a little bit more information than that.

• Which signaling/nodejs ?
• Did you follow the integration manual ? https://confluence.temasys.com.sg/display/TWPP/How+to+integrate+the+Temasys+WebRTC+Plugin+into+your+website
• What does you app do ? Where does it hang ?

I have attached my files in zip.

1. Which signaling/nodejs ? Yes

2. Did you follow the integration manual ? https://confluence.temasys.com.sg/display/TWPP/How+to+integrate+the+Temasys+WebRTC+Plugin+into+your+website Yes

3. It hangs on
   function onIceCandidateHandler(evt) {
   console.log("onIceCandidateHandler");
   if (!evt || !evt.candidate) return;
   wsc.send(JSON.stringify({"candidate": evt.candidate }));
   };

Above function called infinitly and my application does not receive ICE candidate

This app works correctly with Mozilla and Chrome

Following STUN server I am using

Sometimes get following exception:

You test samples does not work, but
you can't stringify evt.candidate. It is a plugin object, which is very complex NPAPI/ActiveX object.
You need to make a temporary object with the attributes your are interested in, and stringify it.

Ex:

var c = {
candidate: evt.candidate.candidate,
sdpMLineIndex: evt.candidate.sdpMLineIndex,
sdpMid: evt.candidate.sdpMid
};
JSON.stringify(c);
