Member Function Documentation

FlushAudioData()

TTV_ErrorCode ttv::broadcast::LameAudioEncoder::FlushAudioData ( )

private

GetAudioEncodingFormat()

virtual TTV_ErrorCode ttv::broadcast::LameAudioEncoder::GetAudioEncodingFormat ( AudioFormat &  result )

overridevirtual

Implements ttv::broadcast::IAudioEncoder.

GetName()

virtual std::string ttv::broadcast::LameAudioEncoder::GetName ( ) const

overridevirtual

Retrieves the name for logging purposes.

Implements ttv::broadcast::IAudioEncoder.

GetNumInputSamplesPerEncodeFrame()

virtual TTV_ErrorCode ttv::broadcast::LameAudioEncoder::GetNumInputSamplesPerEncodeFrame ( uint32_t &  result )

overridevirtual

Assuming the encoder requires a data frame of constant size this is the number of samples in the frame. If it does not need to be constant then result will be 0.

Implements ttv::broadcast::IAudioEncoder.

GetReceiverImplementation()

virtual std::shared_ptr<IAudioFrameReceiver> ttv::broadcast::LameAudioEncoder::GetReceiverImplementation ( IAudioFrameReceiver::ReceiverTypeId  typeId )

overridevirtual

Obtains the receiver for the given protocol. If not implemented, null will be returned.

Implements ttv::broadcast::IAudioEncoder.

Initialize()

virtual TTV_ErrorCode ttv::broadcast::LameAudioEncoder::Initialize ( )

overridevirtual

Implements ttv::broadcast::IAudioEncoder.

SetFrameWriter()

virtual TTV_ErrorCode ttv::broadcast::LameAudioEncoder::SetFrameWriter ( const std::shared_ptr< IFrameWriter > &  frameWriter )

overridevirtual

Implements ttv::broadcast::IAudioEncoder.

Shutdown()

virtual TTV_ErrorCode ttv::broadcast::LameAudioEncoder::Shutdown ( )

overridevirtual

Implements ttv::broadcast::IAudioEncoder.

Start()

virtual TTV_ErrorCode ttv::broadcast::LameAudioEncoder::Start ( uint32_t  streamIndex, const AudioParams &  audioParams  )

overridevirtual

Implements ttv::broadcast::IAudioEncoder.

Stop()

virtual TTV_ErrorCode ttv::broadcast::LameAudioEncoder::Stop ( )

overridevirtual

Implements ttv::broadcast::IAudioEncoder.

SubmitFrame()

virtual TTV_ErrorCode ttv::broadcast::LameAudioEncoder::SubmitFrame ( const std::shared_ptr< AudioFrame > &  audioFrame )

overridevirtual

Submits the given audio frame. It should have been created by using the IAudioFrameReceiver implementation returned by GetReceiverImplementation().

Implements ttv::broadcast::IAudioEncoder.

SubmitPcmSamples()

TTV_ErrorCode ttv::broadcast::LameAudioEncoder::SubmitPcmSamples ( const int16_t *  samples, uint32_t  numSamplesPerChannel  )

private

SupportsReceiverProtocol() [1/2]

virtual bool ttv::broadcast::LameAudioEncoder::SupportsReceiverProtocol ( IAudioFrameReceiver::ReceiverTypeId  typeId ) const

overridevirtual

Determines if the concrete implementation supports the given protocol.

Implements ttv::broadcast::IAudioEncoder.

SupportsReceiverProtocol() [2/2]

template<typename T >

bool ttv::broadcast::IAudioEncoder::SupportsReceiverProtocol ( ) const

inlineinherited

Determines if the concrete implementation supports the given protocol. The template parameter must be known to derive from IAudioFrameReceiver.

WritePacket()

TTV_ErrorCode ttv::broadcast::LameAudioEncoder::WritePacket ( )

private
