Client-Side Communication ActionScript 25

Example

The following example sets the width, height, and fps based on the user’s input if the user clicks

the button. The optional argument,

favorSize is not included, because the default value, true,

will provide the settings closest to the user’s preference without sacrificing the picture quality,

although the fps may then be sacrificed. The user interface is then updated with the new settings.

on (press)

{

// Sets width, height, and fps to user’s input.

_root.myCam.setMode(txt_width, txt_height, txt_fps);

// Update the user’s text fields with the new settings.

_root.txt_width = myCam.width;

_root.txt_height = myCam.height;

_root.txt_fps = myCam.fps;

}

Availability

• Flash Player 6.

• Flash Communication Server MX (not required).

Usage

activeCamera.setMotionLevel(sensitivity [, timeout])

Parameters

sensitivity A numeric value that specifies the amount of motion required to invoke

Camera.onActivity(true). Acceptable values range from 0 to 100. The default value is 50.

timeout An optional numeric parameter that specifies how many milliseconds must elapse

without activity before Flash considers activity to have stopped and invokes

Camera.onActivity(false). The default value is 2000 (2 seconds).

Returns

Nothing.

Description

Method; specifies how much motion is required to invoke Camera.onActivity(true).

Optionally sets the number of milliseconds that must elapse without activity before Flash

considers motion to have stopped and invokes

Camera.onActivity(false).

Note: Video can be displayed regardless of the value of the sensitivity parameter. This parameter only

determines when and under what circumstances Camera.onActivity is invoked, not whether video is actually

being captured or displayed.

• To prevent the camera from detecting motion at all, pass a value of 100 for sensitivity;

Camera.onActivity is never invoked. (You would probably use this value only for testing

purposes—for example, to temporarily disable any actions set to occur when

Camera.onActivity is invoked.)

• To determine the amount of motion the camera is currently detecting, use

Camera.activityLevel.
