Description
Determines the media-type of a stream. It applies typefind functions in the order of their rank. Once the type has been detected it sets its src pad caps to the found media type.
Whenever a type is found the “have-type” signal is emitted, either from the streaming thread or the application thread (the latter may happen when typefinding is done pull-based from the state change function).
Plugins can register custom typefinders by using GstTypeFindFactory.
