Re: [discuss-webrtc] Is it possible to use WEBRTC without audio and camera locally?

[PhistucK]

I believe you can. Just skip the code where you (create or) add a stream.

WebRTC is normally used for video chat. 

But is it possible to create the peerconnection without audio input and camera stream locally?

It maybe the good scenario which can be used for video monitor.

Thanks

I have tested the following code on Windows7, but createOffer will throw the exception: SYNTAX_ERR: DOM Exception 12

var pc = new window.webkitPeerConnection00("STUN stun.l.google.com:19302", function(msg) {

console.log(msg);

console.log("Send offer to peer");

});

   var offer = pc.createOffer({has_audio:true, has_video:false});

   pc.setLocalDescription(pc.SDP_OFFER, offer);

   sendMessage({type: 'offer', sdp: offer.toSdp()});

   pc.startIce()

But the above code works on Mac. Does chrome windows version has more strict limitation?

Thanks.

If this works on mac but not on windows, it may indicate a bug. What version of chrome did you use on each platforms?

Can you help file one here?

Thanks for the reply.

I have tested it on Mac with Chrome canary version: 23.0.1262.0 canary. On Windows, I also tested it with Chrome canary, but my chrome canary has updated the latest version on which lots of peerconnection API have been changed. 

But it also can be reproduced with Chrome formal version 21.0.1180.89 m.

BTW, I have not checked this with latest API.

Thanks
