room.publish without video

[Bryan_A_]

Hello !

My problem in js sdk, code:
room = Woogeen.ConferenceClient.create();
localStream = Woogeen.LocalStream.create({video:false, audio: true}, function(err, str){
    if (!err) room.publish(str, {}, function(st) {
     console.log('publish: ok');
    }, function(err) {
     console.log('publish error: '+ err);
    });
});

And i get error: "peer connection failed".

Log from server:

Hi Bryan,

Are you using the latest Chrome 47?

[Bryan_A_]

Hi Chunbo!

Yes, version 47.0.2526.80 m

[Chunbo_H_Intel1]

OK. This is a known issue with the latest version, and we are working on the fix currently.

Thanks!

[Tadas_S_1]

Answer sdp on a=group:BUNDLE have missing audio word, have to be "a=group:BUNDLE audio" , now its empty ("a=group:BUNDLE"). This why Chrome M47 gives error on setting remote description.
