2.12.0

Removed:

• Remove unused samples (users, roster). All cases will be shown at chat, data, webrtc samples;
• The window.navigator.onLine check was remove (the check was move to the WebRTC Sample); To make sure that a client has internet connecteion before make a call;

Fixed:

• during the call (WebRTC session) the WebRTC Sample will be able to switch to other camera, if it is possible and would stop call if all media devices were unplugged;
• bugs were fixed when user doesn't allow permanent permissions for getUserMedia;

Added:

• Ability to restore connect to chat by time interval after disconnect, if it wasn't voluntary (Added for node-xmpp-client and nativescript-xmpp-client, updated for Strophe.js client).
  Add a property chatReconnectionTimeInterval to config, by default is 5 sec;
  QB.chat.disconnect() stops reconnection actions;
• The call of QB.chat.connect(params, callback) when chat is in connecting state (the connection one by one) was blocked, the callback funtion will return an error ('Status.REJECT - The connection is still in the Status.CONNECTING state');
• QB.webrtc.onDevicesChangeListener() was added - the listener that is called when a media device has been plugged or unplugged;
• An ability to change audio and video tracks was added (switch cameras), use the method webRTCSession.switchMediaTracks(deviceIds, cb).
  Supported and tested on Firefox from v.60.

Here is code snippet how to replace audio/video tracks:

var switchMediaTracksBtn = document.getElementById('confirmSwitchMediaTracks');

var webRTCSession = QB.webrtc.createNewSession(params);

QB.webrtc.getMediaDevices('videoinput').then(function(devices) {
    var selectVideoInput = document.createElement('select'),
        selectVideoInput.id = 'videoInput',
        someDocumentElement.appendChild(selectVideoInput);

    if (devices.length > 1) {
        for (var i = 0; i !== devices.length; ++i) {
            var device = devices[i],
                option = document.createElement('option');

            if (device.kind === 'videoinput') {
                option.value = device.deviceId;
                option.text = device.label;
                selectVideoInput.appendChild(option);
            }
        }
    }
}).catch(function(error) {
    console.error(error);
});

QB.webrtc.getMediaDevices('audioinput').then(function(devices) {
    var selectAudioInput = document.createElement('select'),
        selectAudioInput.id = 'audioInput',
        someDocumentElement.appendChild(selectAudioInput);

    if (devices.length > 1) {
        for (var i = 0; i !== devices.length; ++i) {
            var device = devices[i],
                option = document.createElement('option');

            if (device.kind === 'audioinput') {
                option.value = device.deviceId;
                option.text = device.label;
                selectAudioInput.appendChild(option);
            }
        }
    }
}).catch(function(error) {
    console.error(error);
});

switchMediaTracksBtn.onclick = function(event) {
    var audioDeviceId = document.getElementById('audioInput').value || undefined,
        videoDeviceId = document.getElementById('videoInput').value || undefined,
        deviceIds = {
            audio: audioDeviceId,
            video: videoDeviceId,
        };

    var callback = function(error, stream) {
            if (err) {
                console.error(error);
            } else {
                console.log(stream);
            }
         };

    // Switch media tracks in audio/video HTML's element (the local stream)
    // replace media tracks in peers (will change media tracks for each user in WebRTC session)
    webRTCSession.switchMediaTracks(deviceIds, callback);
