Methods
-------

.. rst-class:: interim-class

.. class:: TypeFindFactory
   :no-index:


   .. method:: call_function(find: ~gi.repository.Gst.TypeFind) -> None

      Calls the :obj:`~gi.repository.Gst.TypeFindFunction` associated with this factory.







      :param find: a properly setup :obj:`~gi.repository.Gst.TypeFind` entry. The get_data
         and suggest_type members must be set.





   .. method:: get_caps() -> ~gi.repository.Gst.Caps | None

      Gets the :obj:`~gi.repository.Gst.Caps` associated with a typefind factory.










   .. method:: get_extensions() -> list[str] | None

      Gets the extensions associated with a :obj:`~gi.repository.Gst.TypeFindFactory`. The returned
      array should not be changed. If you need to change stuff in it, you should
      copy it using :func:`~gi.repository.GLib.strdupv`.  This function may return :const:`None` to indicate
      a 0-length list.










   .. method:: get_list() -> list[~gi.repository.Gst.TypeFindFactory]

      Gets the list of all registered typefind factories. You must free the
      list using :func:`~gi.repository.Gst.PluginFeature.list_free`.

      The returned factories are sorted by highest rank first, and then by
      factory name.

      Free-function: gst_plugin_feature_list_free










   .. method:: has_function() -> bool

      Check whether the factory has a typefind function. Typefind factories
      without typefind functions are a last-effort fallback mechanism to
      e.g. assume a certain media type based on the file extension.
