Member Function Documentation

◆ BeginChunk()

TTV_ErrorCode ttv::broadcast::FlvMuxer::BeginChunk	(	flv::TagTypes	type,
		uint32_t	timestamp,
		size_t	length
	)

private

◆ EndChunk()

TTV_ErrorCode ttv::broadcast::FlvMuxer::EndChunk ( size_t length )

private

◆ GetAverageSendBitRate()

TTV_ErrorCode ttv::broadcast::FlvMuxer::GetAverageSendBitRate	(	uint64_t	measurementWindowMilliseconds,
		uint64_t &	bitsPerSecond
	)		const

Computes the average sending bit rate in bits per second over a sliding window.

◆ GetCongestionLevel()

TTV_ErrorCode ttv::broadcast::FlvMuxer::GetCongestionLevel	(	uint64_t	measurementWindowMilliseconds,
		double &	congestionLevel
	)		const

Returns the fraction of time spent blocking on the socket over a sliding window.

◆ GetError()

TTV_ErrorCode ttv::broadcast::FlvMuxer::GetError ( )

Retrieves the fatal error if the stream has become invalid.

◆ SetFlvPath()

void ttv::broadcast::FlvMuxer::SetFlvPath ( const std::wstring & path )

inline

◆ SetRtmpUrl()

void ttv::broadcast::FlvMuxer::SetRtmpUrl ( const std::string & url )

inline

◆ Start()

virtual TTV_ErrorCode ttv::broadcast::FlvMuxer::Start ( const MuxerParameters & parameters )

overridevirtual

Specifies that the encoding has begun.

Parameters

parameters The parameters of the encoding.

Returns

TTV_EC_SUCCESS if the start is successful.
Any other error code otherwise. This will prevent the encoding stream from continuing if this is the only muxer.

Implements ttv::broadcast::IMuxer.

◆ Stop()

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

overridevirtual

Specifies that the encoding has stopped.

Returns: TTV_EC_SUCCESS if the stop is successful. Any errors returned from this will be ignored.

Implements ttv::broadcast::IMuxer.

◆ Update()

void ttv::broadcast::FlvMuxer::Update ( )

◆ WriteAudioHeader()

TTV_ErrorCode ttv::broadcast::FlvMuxer::WriteAudioHeader	(	uint8_t	audioFlags,
		AudioFormat	encodingFormat
	)

private

◆ WriteAudioPacket()

virtual TTV_ErrorCode ttv::broadcast::FlvMuxer::WriteAudioPacket ( const Packet & packet )

overridevirtual

Writes an audio packet to the stream.

Parameters

packet The audio data.

Returns

TTV_EC_SUCCESS if the writing is successful.
Any other error code otherwise. This will stop the encoding stream if this is the only muxer.

Implements ttv::broadcast::IMuxer.

◆ WriteMetaPacket()

TTV_ErrorCode ttv::broadcast::FlvMuxer::WriteMetaPacket ( const std::shared_ptr< AMF0Encoder > & encoder )

private

◆ WriteToOutput() [1/3]

◆ WriteVideoPacket()

virtual TTV_ErrorCode ttv::broadcast::FlvMuxer::WriteVideoPacket ( const Packet & packet )

overridevirtual

Writes a video packet to the stream.

Parameters

packet The video data.

Returns

TTV_EC_SUCCESS if the writing is successful.
Any other error code otherwise. This will stop the encoding stream if this is the only muxer.

Implements ttv::broadcast::IMuxer.

◆ WriteVideoSpsPps()

virtual TTV_ErrorCode ttv::broadcast::FlvMuxer::WriteVideoSpsPps	(	const std::vector< uint8_t > &	sps,
		const std::vector< uint8_t > &	pps
	)

overridevirtual

Writes the video SPS and PPS to the stream. This needs to be done before an IDR frame that it applies to.

Parameters

sps	The video SPS data.
pps	The video PPS data.

Returns

TTV_EC_SUCCESS if the writing is successful.
Any other error code otherwise. This will stop the encoding stream if this is the only muxer.

Implements ttv::broadcast::IMuxer.
