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.
