var my_video:Video;
var activity_pb:mx.controls.ProgressBar;
var my_cam:Camera = Camera.get();
my_video.attachVideo(my_cam);
activity_pb.mode = "manual";
activity_pb.label = "Activity %3%%";
this.onEnterFrame = function() {
activity_pb.setProgress(my_cam.activityLevel, 100);
};
my_cam.onActivity = function(isActive:Boolean) {
var themeColor:String = (isActive) ? "haloGreen" : "haloOrange";
activity_pb.setStyle("themeColor", themeColor);

active_cam.bandwidth:Number
Description
Read-only property; an integer that specifies the maximum amount of bandwidth the current
outgoing video feed can use, in bytes. A value of 0 means that Flash video can use as much

To set this property, use
Example
The following example changes the maximum amount of bandwidth used by the camera feed.
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.";
