Camera
385
Example
The following example changes the maximum amount of bandwidth used by the camera feed.
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 NumericStepper
component instance to the Stage and give it the instance name
bandwidth_nstep
. Then add
the following ActionScript to Frame 1 of the Timeline:
var bandwidth_nstep:mx.controls.NumericStepper;
var my_video:Video;
var my_cam:Camera = Camera.get();
my_video.attachVideo(my_cam);
this.createTextField("bandwidth_txt", this.getNextHighestDepth(), 0, 0,
100, 22);
bandwidth_txt.autoSize = true;
this.onEnterFrame = function() {
bandwidth_txt.text = "Camera is currently using "+my_cam.ba"
bytes ("+Math.round(my_cam.bandwidth/1024)+" KB) bandwidth.";
};
//
bandwidth_nstep.minimum = 0;
bandwidth_nstep.maximum = 128;
bandwidth_nstep.stepSize = 16;
bandwidth_nstep.value = my_cam.bandwidth/1024;
function changeBandwidth(evt:Object) {
my_cam.setQuality(evt.target.value 1024, 0);
}
bandwidth_nstep.addEventListener("change", changeBandwidth);
The
MovieClip.getNextHighestDepth()
method used in this example requires Flash Player
7 or later. If your SWF file includes a version 2 component, use the version 2 components
DepthManager class instead of the
MovieClip.getNextHighestDepth()
method.

setQuality (Camera.setQuality method)
currentFps (Camera.currentFps property)
public currentFps : Number [read-only]
The rate at which the camera is capturing data, in frames per second. This property cannot be
set; however, you can use the
Camera.setMode()
method to set a related property--
Camera.fps
--which specifies the maximum frame rate at which you would like the camera to
capture data.
