GstPlugin
Dynamically loadable Elements
GStreamer is extensible so GstElements can be loaded at runtime. A plugin
system can provide one or more of the following basic GStreamer
objects factories:
A #GstElementFactory: the components to build a pipeline.
A #GstTypeFactory: A MIME type and an optional typefind function.
A #GstAutoplugFactory: An object used to automatically construct pipelines.
A plugin should export a symbol plugin_desc that is a struct of type #GstPluginDesc.
the plugin loader will check the version of the core library the plugin was linked against
and will create a new #GstPlugin. It will then call the #GstPluginInitFunc function
that was provided in the plugin_desc.
Optionally a new plugin is created with gst_plugin_new(). this function will return a handle
to the GstPlugin or NULL if the plugin could not be created.
Once you have a handle to a #GstPlugin, you can add the different types of factories
to it with gst_plugin_add_factory(), gst_plugin_add_type(), gst_plugin_add_autoplugger().
use gst_plugin_find(), gst_plugin_get_list(), gst_plugin_get_factory_list(), gst_plugin_get_type_list() and
gst_plugin_get_autoplug_list() to query the plugin repository.
Plugins are always automaticlly loaded so you don't need to call gst_plugin_load() explicitly
to bring it into memory.

A plugin should provide a pointer to a function of this type in the plugin_desc struct.
It will be called by the loader at statup.
@module: The GModule it was loaded from
@plugin: The plugin object that can be used to register stuff for this plugin.
@Returns: A boolean indicating success or failure.
A plugins should export a variable of this type called plugin_desc. This plugin
loaded will use this variable to initialize the plugin.
@major_version: The minor version of the gstreamer library this plugin was created with
@minor_version: The minor version of the gstreamer library this plugin was created with
@name: The name of the plugin
@plugin_init: The init function of this plugin.
