Inheritance diagram for OpusOggDecoder:

Public Member Functions
void	addNotifyAudioChange (AudioInfoSupport &bi) override
	Adds target to be notified about audio changes.

AudioInfo	audioInfo () override
	provides the actual input AudioInfo

virtual AudioInfo	audioInfoOut ()
	provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream

bool	begin () override

bool	begin (AudioInfo info) override

bool	begin (OpusSettings settings)

virtual void	clearNotifyAudioChange ()
	Deletes all change notify subscriptions.

OpusSettings &	config ()
	Provides access to the Opus configuration.

void	end () override

void	flush ()

bool	isNotifyActive ()
	Checks if the automatic AudioInfo update is active.

virtual	operator bool () override

virtual bool	removeNotifyAudioChange (AudioInfoSupport &bi)
	Removes a target in order not to be notified about audio changes.

virtual void	setAudioInfo (AudioInfo from) override
	for most decoders this is not needed

void	setDecoder (AudioDecoder *decoder)

void	setNotifyActive (bool flag)
	Deactivate/Reactivate automatic AudioInfo updates: (default is active)

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.

void	setOutput (Print &print) override
	Defines the output Stream.

virtual size_t	write (const void *in_ptr, size_t in_size) override

Public Attributes
int	id
	custom id to be used by application
