Camera class 13
The
MovieClip.getNextHighestDepth()
method used in this example requires Flash Player
7 or later. If your SWF file includes a v2 component (version 2 of the Macromedia
Component Architecture), use the DepthManager class from the component framework
instead of the
MovieClip.getNextHighestDepth()
method.

Availability
■
Flash Player 6.
■
Flash Media Server (not required).
Usage
public currentFps : Number [read-only]
Description
Property (read-only); the rate at which the camera is capturing data, in frames per second.
This property cannot be set; however, you can use
Camera.setMode()
to set a related
property—
Camera.fps
—which specifies the maximum frame rate at which you would like
the camera to capture data.
Example
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)";
