Choose default webcam for node-webkit - google-chrome

Question

I have a node-webkit application that is using RecordRTC to capture a snippet of video. I'm running the application on a Windows Surface Pro 3, and need the front-facing webcam to be used instead of the back-facing one. I know there is a setting in Chrome to change the default webcam, but how do I configure this in node-webkit?

Answer 1

I don't have a device to test this on but it should work. I believe mobile devices will return either 'user' or 'environment' to determine if it's front or rear facing.
var devices = function (devices) {
for (var i = 0; i !== devices.length; ++i) {
var camera = devices[i];
if (camera.kind === 'video' && camera.facing === 'user') {
createStream(camera.id);
} else {
console.log('No front facing camera');
}
}
}
var createStream = function(id) {
var settings = {video: {optional: {sourceId: id} }};
navigator.webkitGetUserMedia(settings, successCallback, errorCallback);
};
MediaStreamTrack.getSources(devices);
This basically loops through all of the available devices and checks if it's a video source and that it is facing the user. It will then use the id of that device to create the media stream.
