Constructor & Destructor Documentation

Packetizer()

roc::audio::Packetizer::Packetizer	(	packet::IWriter &	writer,
		packet::IComposer &	composer,
		packet::ISequencer &	sequencer,
		IFrameEncoder &	payload_encoder,
		packet::PacketFactory &	packet_factory,
		core::nanoseconds_t	packet_length,
		const SampleSpec &	sample_spec
	)

Initialization.

Parameters

• writer is used to write generated packets
• composer is used to initialize new packets
• sequencer is used to put packets in sequence
• payload_encoder is used to write samples to packets
• packet_factory is used to allocate packets
• buffer_factory is used to allocate buffers for packets
• packet_length defines packet length in nanoseconds
• sample_spec describes input frames

Member Function Documentation

flush()

void roc::audio::Packetizer::flush

(

)

(

)

const

Check if object is successfully constructed.

metrics()

const PacketizerMetrics& roc::audio::Packetizer::metrics

(

)

const

Get metrics.

sample_rate()

size_t roc::audio::Packetizer::sample_rate

(

)

const

Get sample rate.

write()

virtual void roc::audio::Packetizer::write ( Frame &  frame )

virtual

Write audio frame.

Implements roc::audio::IFrameWriter.
