Public Member Functions

virtual void addNotifyAudioChange (AudioInfoSupport &bi)
 Adds target to be notified about audio changes.
 
virtual AudioInfo audioInfo ()
 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
 
virtual bool begin (AudioInfo info) override
 
virtual void clearNotifyAudioChange ()
 Deletes all change notify subscriptions.
 
void end () override
 
bool isNotifyActive ()
 Checks if the automatic AudioInfo update is active.
 
virtual operator bool ()=0
 
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 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.
 
virtual void setOutput (Print &out_stream) override
 Defines where the decoded result is written to.
 
virtual size_t write (const uint8_t *data, size_t len)=0
