AS3 Multiple Webcams not showing 3rd webcam - actionscript-3

Question

Hi I'm trying to create a simple AIR 3 application that displays 3 Webcams on the stage. For some reason the 3rd webcam doesn't want to show, it doesn't even turn on the LED indicator on the webcam.
I have tried multiple webcams eg. microsoft, logitech, built in....
The following code doesn't work:
var videoWidth:int = 1000 / totalCols;
var videoHeight:int = 800 / totalRows;
for (var i:int = 0; i < Math.min(Camera.names.length, totalRows * totalCols); i++) {
var currRow:int = Math.floor(i / totalCols);
var currCol:int = i % totalCols;
var video:Video = new Video(videoWidth, videoHeight);
var cam:Camera = Camera.getCamera(i.toString());
if (cam) {
cam.setMode(videoWidth, videoHeight, 30);
video.attachCamera(cam);
video.x = currCol * videoWidth;
video.y = currRow * videoHeight;
StageObj.addChild(video);
}
}
Neither does this:
//camera settings
track_cam = new Camera();
track_cam = Camera.getCamera("1");
track_cam.setMotionLevel(100);
track_cam.setQuality(0, 100);
track_cam.setMode(1920, 1080, 30);
track_feed = new Video();
track_feed.width = track_cam.width;
track_feed.height = track_cam.height;
track_feed.smoothing = true;
track_feed.attachCamera(track_cam);
StageObj.addChild(track_feed);
player_one_cam = new Camera();
player_one_cam = Camera.getCamera("2");
player_one_cam.setMotionLevel(100);
player_one_cam.setQuality(0, 100);
player_one_cam.setMode(200, 200, 30);
player_one_feed = new Video();
player_one_feed.width = player_one_cam.width;
player_one_feed.height = player_one_cam.height;
player_one_feed.smoothing = true;
player_one_feed.attachCamera(player_one_cam);
StageObj.addChild(player_one_feed);
player_one_feed.x = 500;
player_one_feed.y = 500;
player_two_cam = new Camera();
player_two_cam = Camera.getCamera("0");
player_two_cam.setMotionLevel(100);
player_two_cam.setQuality(0, 100);
player_two_cam.setMode(200, 200, 30);
player_two_feed = new Video();
player_two_feed.width = player_two_cam.width;
player_two_feed.height = player_two_cam.height;
player_two_feed.smoothing = true;
player_two_feed.attachCamera(player_two_cam);
StageObj.addChild(player_two_feed);
Is there a limit on the amount of webcams you can use in AS3?

Answer 1

It seems that I ran out of USB Bandwidth, when using usb 3 on a seperate machine it started working.

Answer 2

Looks like it should work from the docs:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/media/Camera.html#getCamera()
name:String (default = null) — Specifies which camera to get, as
determined from the array returned by the names property. For most
applications, get the default camera by omitting this parameter. To
specify a value for this parameter, use the string representation of
the zero-based index position within the Camera.names array. For
example, to specify the third camera in the array, use
Camera.getCamera("2").
