Need help for audio conference using Kurento composite media element in Nodejs - node.js

Question

I am refereeing the code from GitHub for audio AND video conference using Kurento composite media element, It work's fine for audio AND video streaming over WebRTC.
But I need only audio conference using WebRTC, I have added changes in above GitHub code and new code is uploaded on GitHub Repository.
I have added below changes in static/js/index.js file
var constraints = {
audio: true, video: false
};
var options = {
localVideo: undefined,
remoteVideo: video,
onicecandidate : onIceCandidate,
mediaConstraints: constraints
}
webRtcPeer = kurentoUtils.WebRtcPeer.WebRtcPeerSendrecv(options, function(error) {
When I am running this code, no error for node server as well as on chrome console. But audio stream does not get start. It only showing spinner for long time. Chrome console log is here.
As per reply for my previous stack overflow question, We need to specify MediaType.AUDIO in java code like below
webrtc.connect(hubport, MediaType.AUDIO);
hubport.connect(webrtc, MediaType.AUDIO);
But I want to implementing it in Nodejs using kurento-client.js, I did not get any reference to set MediaType.AUDIO to connect with hubPort and webRtcEndpoint in Nodeja API.
Please someone can help me to do code changes for same in Nodejs or suggest me any reference so I can implement only audio conference using composite media element and Nodejs.

Answer 1

This should do
function connectOnlyAudio(source, sink, callback) {
source.connect(sink, "AUDIO" , function(error) {
if (error) {
return callback(error);
}
return callback(null);
});
}
We are in the process of improving the documentation of the project. I hope that this will all be made more clear in the new docs.

It is important to make sure that you are indeed sending something, and that the connection between your client and the media server is negotiated correctly. Going through your bower.json, I've found that you are setting the adapter dependency as whatever, so to speak. In the latest releases, they've done some refactoring that makes the kurento-utils-js library fail. We haven't yet adapted to the new changes, so you need to fix the dependency of adapter.js like so
"adapter.js": "v0.2.9"
