RFC: Support for feature alias
As some inconsistencies exist in the registry such as the couple mpegtsmux/tsdemux. It would be useful to keep a feature name and provide also aliases to instanciate it.
I proposed to add a list of feature's alias in GStPluginFeature and to avoid adding a new GST_ELEMENT_REGISTER method, add a syntax to declare the element such as "feature_name(feature_alias1,feature_alias2):
GST_ELEMENT_REGISTER_DEFINE_WITH_CODE (tsdemux, "tsdemux(mpegtsdemux,tsd)",
GST_RANK_PRIMARY, GST_TYPE_TS_DEMUX, _do_element_init);
