AudioDecoder AudioWriter AudioInfoSource AudioInfoSupport

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
 
virtual bool begin ()
 
virtual bool begin (AudioInfo info) override
 
virtual void clearNotifyAudioChange ()
 Deletes all change notify subscriptions.
 
virtual void end ()
 
bool isNotifyActive ()
 Checks if the automatic AudioInfo update is active.
 
virtual bool isResultPCM ()
 If true, the decoding result is PCM data.
 
 operator bool ()
 
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)
 
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 uint8_t *data, size_t len)
 

Public Attributes

int id
 custom id to be used by application
 

Protected Member Functions

void notifyAudioChange (AudioInfo info)
 
void processByte (uint8_t byte)
 Build decoding buffer and decode when frame is full.
 
void writeBlocking (Print *out, uint8_t *data, size_t len)
