ff_mlp_read_major_sync()

int ff_mlp_read_major_sync	(	void *	log,
		MLPHeaderInfo *	mh,
		GetBitContext *	gb
	)

Read a major sync info header - contains high level information about the stream - sample rate, channel arrangement etc.

Most of this information is not actually necessary for decoding, only for playback. gb must be a freshly initialized GetBitContext with no bits read.
