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

selecting New Video from the Library options menu. Add an instance to the Stage and give it
the instance name
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);
};
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)";
