Inheritance diagram for G722Decoder:

Public Member Functions
virtual AudioInfo	audioInfo ()
virtual void	begin ()
virtual void	begin (AudioInfo cfg)
virtual void	end ()
virtual bool	isResultPCM ()
	If true, the decoding result is PCM data.
	operator bool ()
virtual void	setAudioInfo (AudioInfo cfg)
	for most decoders this is not needed
virtual void	setNotifyAudioChange (AudioInfoSupport &bi)
	Registers an object that is notified if the audio format is changing.
void	setOptions (int options)
	Defines the options for the G.722 Codec: G722_SAMPLE_RATE_8000,G722_PACKED.
virtual void	setOutput (AudioOutput &out_stream)
	Defines where the decoded result is written to.
virtual void	setOutput (AudioStream &out_stream)
	Defines where the decoded result is written to.
virtual void	setOutput (Print &out_stream)
	Defines where the decoded result is written to.
virtual size_t	write (const void *data, size_t length)

Protected Member Functions
void	processByte (uint8_t byte)
	Build decoding buffer and decode when frame is full.
