Camera class 17

Scanning the hardware for cameras takes time. When Flash finds at least one camera, the

hardware is not scanned again for the lifetime of the Flash Player instance. However, if Flash

doesn’t find any cameras, it will scan each time

Camera.get() is called. This is helpful if a

user has forgotten to connect the camera; if your SWF file provides a Try Again button

that calls

Camera.get(), Flash can find the camera without the user having to restart the

SWF file.

Example

The following example lets you select an active camera to use from a ComboBox instance.

The current active camera is displayed in a Label instance. Create a new video instance by

selecting New Video from the Library options menu. Add an instance to the Stage and give it

the instance name

my_video. Add a Label component instance to the Stage and give it the

instance name

camera_lbl, and a ComboBox component instance and give it the instance

name

cameras_cb. Then add the following ActionScript to Frame 1 of the Timeline:

var my_cam:Camera = Camera.get();

var my_video:Video;

my_video.attachVideo(my_cam);

var camera_lbl:mx.controls.Label;

var cameras_cb:mx.controls.ComboBox;

camera_lbl.text = my_cam.name;

cameras_cb.dataProvider = Camera.names;

function changeCamera():Void {

my_cam = Camera.get(cameras_cb.selectedIndex);

my_video.attachVideo(my_cam);

camera_lbl.text = my_cam.name;

}

cameras_cb.addEventListener("change", changeCamera);

camera_lbl.setStyle("fontSize", 9);

cameras_cb.setStyle("fontSize", 9);
