In this section, we will solely discuss how to embed such elements statically in your application. This can be useful for application-specific elements that have no use elsewhere in GStreamer. +Elements do not need to be registered to be used in GStreamer, so one +can simply instantiate the elements with `g_object_new ()` and use them +in pipelines like any other. + +If the statically linked elements should also be available through a +name for functions such as `gst_element_factory_make ()`, these elements +can be registered direclty without a plugin.

This structure is loaded when the plugin is loaded by the GStreamer core. The structure contains an initialization function (usually called `plugin_init`) that will be called right after that.
