Public Member Functions
	StreamingDecoderAdapter (AudioDecoder &decoder, int copySize=DEFAULT_BUFFER_SIZE)
virtual void	addNotifyAudioChange (AudioInfoSupport &bi)
	Adds target to be notified about audio changes.
AudioInfo	audioInfo () override
	Provides the last available MP3FrameInfo.
bool	begin () override
	Starts the processing.
virtual void	clearNotifyAudioChange ()
	Deletes all change notify subscriptions.
virtual bool	copy ()
	Process a single read operation - to be called in the loop.
void	end () override
	Releases the reserved memory.
bool	isNotifyActive ()
	Checks if the automatic AudioInfo update is active.
virtual	operator bool ()
	checks if the class is active
virtual bool	removeNotifyAudioChange (AudioInfoSupport &bi)
	Removes a target in order not to be notified about audio changes.
void	resize (int bufferSize)
	Adjust the buffer size: the existing content of the buffer is lost!
void	setInput (Stream &inStream)
void	setNotifyActive (bool flag)
	Deactivate/Reactivate automatic AudioInfo updates: (default is active)
virtual void	setOutput (AudioOutput &out_stream)
	Defines the output streams and register to be notified.
virtual void	setOutput (AudioStream &out_stream)
	Defines the output streams and register to be notified.
void	setOutput (Print &out_stream) override
	Defines the output Stream.

Stream Interface: Decode directly by taking data from the stream. This is more efficient then feeding the decoder with write: just call copy() in the loop
