OggContainerEncoder Class Reference

Encoder for Ogg Container. Encodes a packet for an Ogg container. The Ogg begin segment contains the AudioInfo structure. You can subclass ond overwrite the writeHeader() method to implement your own header logic. When an optional encoder is specified in the constructor we package the encoded data.

audioInfo()

AudioInfo audioInfo ( )

inlinevirtualinherited

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, and ResampleStream.

begin() [1/2]

virtual bool begin ( )

inlineoverridevirtual

starts the processing using the actual AudioInfo

Implements AudioWriter.

begin() [2/2]

virtual bool begin ( AudioInfo  from )

inlineoverridevirtual

Reimplemented from AudioWriter.

end()

void end ( )

inlineoverridevirtual

stops the processing
