606 FLVPlayback Component (Flash Professional Only)

Description

Property; a Boolean value that, if true, maintains the video aspect ratio. If this property is

changed from

false to true and the autoSize property is false after an FLV file has been

loaded, an automatic resize of the video starts immediately. The default value is

true.

Example

The following example calls the setSize() method to change the size of the FLVPlayback

instance, causing a

resize event. The maintainAspectRatio property, which defaults to

true, forces a second resize event to maintain the aspect ratio. The resize event handler

displays the width and height of the resized FLVPlayback instance for both occurrences in the

Output panel. If you set

maintainAspectRatio to false, the dimensions specified by the

setSize() method take effect.

Drag an FLVPlayback component to the Stage, and give it an instance name of

my_FLVPlybk. Then add the following code to the Actions panel on Frame 1 of the

Timeline:

/**

Requires:

- FLVPlayback component on the Stage with an instance name of my_FLVPlybk

import mx.video.*;

// maintainAspectRatio defaults to true, causing resize when size changes.

// Remove the comment delimiters from the following line to disable resize.

// my_FLVPlybk.maintainAspectRatio = false;

var listenerObject:Object = new Object();

listenerObject.resize = function(eventObject:Object) {

trace("resize event; Width is: " + eventObject.target.width + " Height

is: " + eventObject.target.height);

};

my_FLVPlybk.addEventListener("resize", listenerObject);

my_FLVPlybk.contentPath = "http://www.helpexamples.com/flash/video/

water.flv";

my_FLVPlybk.setSize(300, 300);
