bandwidth (Camera.bandwidth property) -- Flash CS3

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 bandwidth as needed to maintain the desired frame quality.

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.
