81  * GStreamer is extensible, so GstElement instances can be loaded at runtime.
82  * A plugin system can provide one or more of the basic
83  * GStreamer GstPluginFeature subclasses.
84  *
85  * A plugin should export a symbol gst_plugin_desc that is a
86  * struct of type GstPluginDesc.
87  * the plugin loader will check the version of the core library the plugin was
88  * linked against and will create a new GstPlugin. It will then call the
89  * GstPluginInitFunc function that was provided in the
90  * gst_plugin_desc.
91  *
92  * Once you have a handle to a GstPlugin (e.g. from the GstRegistry), you
93  * can add any object that subclasses GstPluginFeature.
94  *
95  * Usually plugins are always automaticlly loaded so you don't need to call
96  * gst_plugin_load() explicitly to bring it into memory. There are options to
97  * statically link plugins to an app or even use GStreamer without a plugin
98  * repository in which case gst_plugin_load() can be needed to bring the plugin
99  * into memory.
