The following example detects the rate in frames per second that the camera captures data, using

the

currentFps property and a ProgressBar instance. 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 ProgressBar component instance to the Stage and give it the instance

name

fps_pb. Then add the following ActionScript to Frame 1 of the Timeline:

var my_video:Video;

var fps_pb:mx.controls.ProgressBar;

var my_cam:Camera = Camera.get();

my_video.attachVideo(my_cam);

this.onEnterFrame = function() {

fps_pb.setProgress(my_cam.fps-my_cam.currentFps, my_cam.fps);

};

fps_pb.setStyle("fontSize", 10);

fps_pb.setStyle("themeColor", "haloOrange");

fps_pb.labelPlacement = "top";

fps_pb.mode = "manual";

fps_pb.label = "FPS: %2 (%3%% dropped)";
