Client-Side Communication ActionScript 13

Example

The following example sets the fps rate of the active camera, myCam.fps, to the value provided by

the user’s text box,

this.config.txt_fps.

if (this.config.txt_fps != undefined) {

myCam.setMode(myCam.width, myCam.height, this.config.txt_fps, false);

}

Note: The setMode function does not guarantee the requested fps setting; it sets the fps you requested or the

fastest fps available.

Camera.currentFps, Camera.setMode

Camera.get

Availability

• Flash Player 6.

• Flash Communication Server MX (not required).

Usage

Camera.get([index])

Note: The correct syntax is Camera.get(). To assign the Camera object to a variable, use syntax like

activeCamera = Camera.get().

Parameters

index An optional zero-based integer that specifies which camera to get, as determined from

the array returned by

Camera.names. To get the default camera (which is recommended for most

applications), omit this parameter.

Returns

• If index is not specified, this method returns a reference to the default camera or, if it is in use

by another application, to the first available camera. (If there is more than one camera

installed, the user may specify the default camera in the Flash Player Camera Settings panel.) If

no cameras are available or installed, the method returns

null.

• If index is specified, this method returns a reference to the requested camera, or null if it is

not available.

Description

Method; returns a reference to a Camera object for capturing video. To actually begin capturing

the video, you must attach the Camera object either to a Video object (see

Video.attachVideo)

or to a NetStream object (see

NetStream.attachVideo). (The NetStream object is available only

with Flash Communication Server.)

Unlike objects that you create using the

new constructor, multiple calls to Camera.get reference

the same camera. Thus, if your script contains the lines

cam1 = Camera.get() and

cam2 = Camera.get(), both cam1 and cam2 reference the same (default) camera.

In general, you shouldn’t pass a value for

index; simply use Camera.get() to return a reference

to the default camera. By means of the Camera settings panel (discussed later in this section), the

user can specify the default camera Flash should use. If you pass a value for

index, you might be

trying to reference a camera other than the one the user prefers. You might use

index in rare

cases—for example, if your application is capturing video from two cameras at the same time.
