Camera.setMode

Availability

• Flash Player 6.

• Flash Communication Server MX (not required).

Usage

activeCamera.setMode(width, height, fps [,favorSize])

Parameters

width The requested capture width, in pixels. The default value is 160.

height The requested capture height, in pixels. The default value is 120.

fps The requested rate at which the camera should capture data, in frames per second. The

default value is 15.

favorSize An optional Boolean parameter that specifies how to manipulate the width, height,

and frame rate if the camera does not have a native mode that meets the specified requirements.

The default value is

true, which means that maintaining capture size is favored; the mode that

most closely matches width and height is selected, even if doing so adversely affects performance

by reducing the frame rate. To maximize frame rate at the expense of camera height and width,

pass

false for favorSize.

Returns

Nothing.

Description

Method; sets the camera capture mode to the native mode that best meets the specified

requirements. If the camera does not have a native mode that matches all the parameters you pass,

Flash selects a capture mode that most closely synthesizes the requested mode. This manipulation

may involve cropping the image and dropping frames.

By default, Flash drops frames as needed to maintain image size. To minimize the number of

dropped frames, even if this means reducing the size of the image, pass

false for favorSize.

When choosing a native mode, Flash tries to maintain the requested aspect ratio whenever

possible. For example, if you issue the command

activeCamera.setMode(400, 400, 30), and

the maximum width and height values available on the camera are 320 and 288, Flash sets both

the width and height at 288; by setting these properties to the same value, Flash maintains the 1:1

aspect ratio you requested.

To determine the values assigned to these properties after Flash selects the mode that most closely

matches your requested values, use

Camera.width, Camera.height, and Camera.fps.

If you are using Flash Communication Server, you can also capture single frames or create time-

lapsed photography. For more information, see

NetStream.attachVideo.
