/**
 * GStreamer is extensible, so GstElement instances can be loaded at runtime.
 * A plugin system can provide one or more of the basic
 * GStreamer GstPluginFeature subclasses.
 *
 * A plugin should export a symbol gst_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
 * gst_plugin_desc.
 *
 * Once you have a handle to a GstPlugin (e.g. from the GstRegistry), you
 * can add any object that subclasses GstPluginFeature.
 *
 * Usually plugins are always automaticlly loaded so you don't need to call
 * gst_plugin_load() explicitly to bring it into memory. There are options to
 * statically link plugins to an app or even use GStreamer without a plugin
 * repository in which case gst_plugin_load() can be needed to bring the plugin
 * into memory.
