Does Kurento-utils WebRtcPeerSendrecv pay attention to all options?

Question

I'm using WebRtcPeerSendrecv object to build a communication with WebRTC endpoint with kurento server. I want to select a video input as it is made here: https://webrtc.github.io/samples/src/content/devices/input-output/

The problem I have is that adding a property video/deviceId is not working.

options = {
    audio : false,
    localVideo : videoInput,
    remoteVideo : videoOutput,
    video: {
        deviceId: {exact: devcs[0]}
        },
    onicecandidate : onIceCandidate,
    onerror : onError
}

The only thing which is made in other way, is that I'm building my WebRtc connection with WebRtcPeerSendrecv from Kurento-utils, and originally it is made with using navigator.getUserMedia(...). As far as I know, WebRtcPeerSendrecv is calling getUserMedia, but I'm not sure that all properties are copied one to one. I took a look here for source code of https://github.com/Kurento/kurento-utils-js/blob/master/lib/WebRtcPeer.js but I'm not sure of it. Have anyone faced with a simmilar problem?

Edit:

There is wider sourcecode which is containing a webRTCPeer creation (with tetsting another options):

var options;
    console.log(devcs);
    if(devcs.length == 2){
        console.log("CAMERA ID SET");
        options = {
            audio : false,
            localVideo : videoInput,
            remoteVideo : videoOutput,
            video: {
                optional: [{sourceId: devcs[0]}]
                //deviceId: {exact: devcs[0]}
            },
            onicecandidate : onIceCandidate,
            onerror : onError
        }
    }
    else{
        console.log("THERE ARE NO 2 CAMERAS");
        options = {
                audio : false,
                localVideo : videoInput,
                remoteVideo : videoOutput,
                onicecandidate : onIceCandidate,
                onerror : onError
            }
    }
    webRtcPeer = new kurentoUtils.WebRtcPeer.WebRtcPeerSendrecv(options,
            function(error) {
                if (error) {
                    return console.error(error);
                }
                webRtcPeer.generateOffer(onOfferIncomingCall);
            });

I have tried with both options with both IDs which I'm getting in a devcs array, and both are not working- I have always a front camera. As I checked, the devcs contains IDs. There is way in which I obtain them.

There are some log, but not too much (log from android- I'm building it in WebView (chromium)):

Answer 1

The solution is not connected with kurento client. Video properties must be added through a mediaConstraint option:

var constraints = {
                audio:true,
                video:{
                    deviceId: {exact: devcs[1]}
                }
        };
        options = {
            audio : false,
            localVideo : videoInput,
            remoteVideo : videoOutput,
            mediaConstraints:constraints,
            onicecandidate : onIceCandidate,
            onerror : onError
        }

The other problem which I'm facing right now is that camera is working well with only one video id : with devcs[0]. Whith second camera (devcs[1]) there is black video element and error in logs:

12-21 13:09:12.562 9704-9757/eu.kros.t_medapp W/CameraBase: An error occurred while connecting to camera: 0

12-21 13:09:12.5629704-9757/eu.kros.t_medapp E/cr_VideoCapture: allocate: Camera.open: java.lang.RuntimeException: Fail to connect to camera service

12-21 13:09:12.568 9704-9757/eu.kros.t_medapp E/cr_VideoCapture: stopCapture: mCamera is null

When I will solve it I will update this post.
