Member Function Documentation

addNotifyAudioChange()

virtual void addNotifyAudioChange ( AudioInfoSupport &  bi )

inlinevirtualinherited

Adds target to be notified about audio changes.

Reimplemented in CodecNOP, MP3DecoderMAD, EncodedAudioOutput, EncodedAudioStream, AACDecoderFDK, DecoderBasic, MP3DecoderHelix, OggContainerDecoder, Pipeline, and Pipeline::ModifyingStreamAdapter.

audioInfo()

AudioInfo audioInfo ( )

inlineoverridevirtual

Provides the last available MP3FrameInfo.

Implements StreamingDecoder.

begin()

bool begin ( )

inlineoverridevirtual

Starts the processing.

Implements StreamingDecoder.

copy()

virtual bool copy ( )

inlinevirtual

Process a single read operation - to be called in the loop.

Implements StreamingDecoder.

end()

void end ( )

inlineoverridevirtual

Releases the reserved memory.

Implements StreamingDecoder.

operator bool()

virtual operator bool ( )

inlinevirtual

checks if the class is active

Implements StreamingDecoder.

readBytes()

size_t readBytes ( uint8_t *  data, size_t  len  )

inlineoverrideprotectedvirtual

Implements StreamingDecoder.

setInput()

void setInput ( Stream &  inStream )

inlineinherited

Stream Interface: Decode directly by taking data from the stream. This is more efficient then feeding the decoder with write: just call copy() in the loop

setOutput()

void setOutput ( Print &  out_stream )

inlineoverridevirtual

Defines the output Stream.

Reimplemented from StreamingDecoder.
