/*
	The demuxer may connect with pull-mode source filters that may have
	mechanism to identify file type. File Source (Async.) can do this
	so we use MEDIATYPE_Stream/MEDIASUBTYPE_MusepackStream in such cases.
	We will also accept unknown streams.

	Demuxer itself must specify output type so the decoder can connect
	properly. For output pin the demuxer will use
	MEDIATYPE_Audio/MEDIASUBTYPE_MusepackPacket.
