Member Function Documentation

audioInfo()

AudioInfo audioInfo ( )

inlineoverridevirtualinherited

provides the actual input AudioInfo

Implements AudioInfoSupport.

Reimplemented in CodecNOP, and BinaryContainerEncoder.

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, ResampleStream, and ResampleStreamT< TInterpolator >.

begin() [1/2]

bool begin ( )

inlinevirtual

Implements AudioWriter.

begin() [2/2]

virtual bool begin ( AudioInfo  info )

inlinevirtualinherited

Reimplemented in AACEncoderFDK.

end()

virtual void end ( )

pure virtualinherited

Implemented in AACDecoderFAAD, MP3DecoderMini, SBCEncoder, AACDecoderHelix, EncoderBase64, EncoderBasic, FLACEncoder, EncoderFloat, EncoderL16, EncoderL8, MP3DecoderHelix, MP3DecoderMAD, MTSDecoder, OpusAudioEncoder, WAVEncoder, ContainerM4A, OggContainerEncoder, and MultiDecoder.

mime()

const char * mime ( )

inlinevirtual

Provides the mime type of the encoded result.

Implements AudioEncoder.

operator bool()

virtual operator bool ( )

pure virtualinherited

Implemented in AACDecoderFAAD, EncoderALAC, MP3DecoderMini, AACDecoderHelix, ADTSDecoder, MP3DecoderHelix, MP3DecoderMAD, and ContainerM4A.

setAudioInfo()

void setAudioInfo ( AudioInfo  info )

inlinevirtual
