PluginInfo is the encapsulation of the set of MediaFactoryItem objects that will be available to the application after the plugin has been successfully loaded. Every Open Source Media Framework plugin must define an instance or subclass of PluginInfo to provide the application with the information it needs to create and load the plugin's MediaElement.

From the point of view of the Open Source Media Framework, the plugin's purpose is to expose the MediaFactoryItem objects that represent the media that the plugin handles. These MediaFactoryItem objects could describe standard media types such as video, audio, or image that can be represented by the built-in Open Source Media Framework MediaElements: VideoElement, AudioElement, or ImageElement. More likely, a plugin provides some type of specialized processing, such as a custom loader or special-purpose media element with custom implementations of the traits. For example, a plugin that provides tracking might implement a TrackingCompositeElement that includes a customized loader and a customized PlayTrait implementation that start and stop tracking as well as the video.

A PluginInfo also gives the plugin an opportunity to accept or reject a specific Open Source Media Framework version through its isFrameworkVersionSupported() method.

A dynamic plugin is loaded at runtime from a SWF. A static plugin is compiled as part of the Open Source Media Framework application. An application attempting to load a dynamic plugin accesses the class that extends PluginInfo through the pluginInfo property on the root of the plugin SWF. If this class is not found, the plugin is not loaded. An application attempting to load a static plugin accesses the PluginInfo exposed by the PluginInfoResource object.

Constante

public static const PLUGIN_MEDIAFACTORY_NAMESPACE:String = "http://www.osmf.org/plugin/mediaFactory/1.0"

Metadata namespace URL for a MediaFactory that is passed from player to plugin.

Client code can set this on the MediaResourceBase that is passed to MediaFactory.loadPlugin, and it will be exposed to the plugin on the MediaResourceBase that is passed to PluginInfo.initializePlugin.

	`mediaFactoryItems:Vector.<MediaFactoryItem>` (default = `null`) — Vector of MediaFactoryItem objects that this plugin exposes.

	`mediaElementCreationNotificationFunction:Function` (default = `null`) — Optional function which, if specified, is invoked for each MediaElement that is created from the MediaFactory to which this MediaFactoryItem is added. If specified, the function must take one param of type MediaElement, and return void. This callback function is useful for MediaFactoryItems which need to be notified when other MediaElements are created (e.g. so as to listen to or control them).
