In a full implementation of this interface (i.e. all methods implemented), the interface initialization function used in `G_IMPLEMENT_INTERFACE()` would typically look like this:

    static void
    implement_media_stream_handler (gpointer klass,
        gpointer unused G_GNUC_UNUSED)
    {
    #define IMPLEMENT(x) tp_svc_media_stream_handler_implement_##x (\
      klass, my_object_##x)
      IMPLEMENT (codec_choice);
      IMPLEMENT (error);
