MetaFactory

.. currentmodule:: gi.repository.Gst


.. versionadded:: 1.28




.. class:: MetaFactory(**properties: ~typing.Any)

Superclasses: :class:`~gi.repository.Gst.PluginFeature`, :class:`~gi.repository.Gst.Object`, :class:`~gi.repository.GObject.InitiallyUnowned`, :class:`~gi.repository.GObject.Object`





Register a :obj:`~gi.repository.Gst.MetaInfo` that can be automatically loaded the first time it is
used.

In general, applications and plugins don't need to use the factory
beyond registering the meta in a plugin init function. Once that is
done, the meta is stored in the registry, and ready as soon as the
registry is loaded.
