Member Function Documentation

addNotifyAudioChange()

virtual void addNotifyAudioChange ( AudioInfoSupport &  bi )

inlinevirtualinherited

Adds target to be notified about audio changes.

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

audioInfo()

AudioInfo audioInfo ( )

inlineoverridevirtualinherited

provides the actual input AudioInfo

Implements AudioInfoSupport.

Reimplemented in CodecNOP, GGWaveDecoder, DecoderBasic, MP3DecoderHelix, MP3DecoderMAD, OpusAudioDecoder, WAVDecoder, WavIMADecoder, and OggContainerDecoder.

audioInfoOut()

virtual AudioInfo audioInfoOut ( )

inlinevirtualinherited

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

Reimplemented in PureDataStream, PWMAudioOutput, ChannelFormatConverterStreamT< T >, ChannelFormatConverterStream, NumberFormatConverterStreamT< TFrom, TTo >, NumberFormatConverterStream, FormatConverterStream, Pipeline, and ResampleStream.

begin() [1/2]

inlineoverridevirtualinherited

Reimplemented from AudioWriter.

end()

void end ( )

inlineoverridevirtual

Reimplemented from AudioDecoder.

isResultPCM()

virtual bool isResultPCM ( )

inlinevirtualinherited

Returns true to indicate that the decoding result is PCM data.

Reimplemented in CopyDecoder, and GGWaveDecoder.

operator bool()

operator bool ( )

inlinevirtual

Implements AudioWriter.

setAudioInfo()

void setAudioInfo ( AudioInfo  from )

inlineoverridevirtual

for most decoders this is not needed

Reimplemented from AudioDecoder.

setOutput() [1/3]

virtual void setOutput ( AudioOutput &  out_stream )

inlinevirtualinherited

Defines where the decoded result is written to.

Reimplemented in ADTSDecoder, MTSDecoder, MTSDecoderTSDemux, and MetaDataFilterDecoder.

setOutput() [2/3]
