Usage

active_cam.quality:Number

Description

Read-only property; an integer specifying the required level of picture quality, as determined by

the amount of compression being applied to each video frame. Acceptable quality values range

from 1 (lowest quality, maximum compression) to 100 (highest quality, no compression). The

default value is 0, which means that picture quality can vary as needed to avoid exceeding

available bandwidth.

Example

The following example uses a NumericStepper instance to specify the amount of compression

applied to 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 with the instance name

quality_nstep. Then add the following ActionScript

to Frame 1 of the Timeline:

var quality_nstep:mx.controls.NumericStepper;

var my_cam:Camera = Camera.get();

var my_video:Video;

my_video.attachVideo(my_cam);

quality_nstep.minimum = 0;

quality_nstep.maximum = 100;

quality_nstep.stepSize = 5;

quality_nstep.value = my_cam.quality;

function changeQuality() {

my_cam.setQuality(my_cam.bandwidth, quality_nstep.value);

}

quality_nstep.addEventListener("change", changeQuality);
