Member Function Documentation

audioInfo()

AudioInfo audioInfo ( )

inlineoverridevirtualinherited

provides the actual input AudioInfo

Implements AudioInfoSupport.

Reimplemented in CodecNOP, BinaryContainerEncoder, and MP3ParserEncoder.

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]

virtual bool begin ( )

inlineoverridevirtual

starts the processing using the actual AudioInfo

Implements AudioWriter.

begin() [2/2]

virtual bool begin ( AudioInfo  info )

inlinevirtualinherited

Reimplemented in AACEncoderFDK.

end()

void end ( )

inlineoverridevirtual

stops the processing

Implements AudioWriter.

frameDurationUs()

virtual uint32_t frameDurationUs ( )

inlinevirtualinherited

Optional rtsp function: provide the frame duration in microseconds.

Reimplemented in ADPCMEncoder, OpusOggEncoder, MP3ParserEncoder, and MetaDataFilterEncoder.

mime()

const char * mime ( )

inlineoverridevirtual

Provides "audio/pcm".

Implements AudioEncoder.

operator bool()

operator bool ( )

inlineoverridevirtual

Implements AudioWriter.

samplesPerFrame()

virtual uint16_t samplesPerFrame ( )

inlinevirtualinherited

Optional rtsp function: provide samples per the frame.

Reimplemented in MP3ParserEncoder, and MetaDataFilterEncoder.

setAudioInfo()

virtual void setAudioInfo ( AudioInfo  from )

inlineoverridevirtual

We update the audio information which will be used in the begin method.

Reimplemented from AudioEncoder.

setOutput()

void setOutput ( Print &  out_stream )

inlineoverridevirtual

Defines the output Stream.

Reimplemented from AudioEncoder.

write()

virtual size_t write ( const uint8_t *  data, size_t  len  )

inlineoverridevirtual

Writes FLAC Packet.

Implements AudioWriter.
