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.bandwidth+"

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.
