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.
 
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
