Detailed Description

Sender session sub-pipeline.

Contains:

• a pipeline for processing audio frames from single sender and converting them into packets

Definition at line 52 of file sender_session.h.

Constructor & Destructor Documentation

SenderSession()

roc::pipeline::SenderSession::SenderSession	(	const SenderSinkConfig &	sink_config,
		const rtp::EncodingMap &	encoding_map,
		packet::PacketFactory &	packet_factory,
		audio::FrameFactory &	frame_factory,
		core::IArena &	arena
	)

Initialize.

Member Function Documentation

create_control_pipeline()

bool roc::pipeline::SenderSession::create_control_pipeline

(

SenderEndpoint *

control_endpoint

)

Create control sub-pipeline.

create_transport_pipeline()

bool roc::pipeline::SenderSession::create_transport_pipeline	(	SenderEndpoint *	source_endpoint,
		SenderEndpoint *	repair_endpoint
	)

Create transport sub-pipeline.

frame_writer()

audio::IFrameWriter * roc::pipeline::SenderSession::frame_writer

(

)

const

Get frame writer.

Remarks

This way samples reach the pipeline. Most of the processing, like encoding packets, generating redundancy packets, etc, happens during the write operation.

get_participant_metrics()

void roc::pipeline::SenderSession::get_participant_metrics	(	SenderParticipantMetrics *	party_metrics,
		size_t *	party_count
	)		const

Get metrics for remote participants.

Remarks

On sender, all participants corresponds to a single SenderSession. In case of unicast, there is only one participant (remote receiver), but in case of multicast, multiple participants may be present.

Note

party_metrics points to array of metrics structs, and party_count defines number of array elements. Metrics are written to given array, and party_count is updated of actual number of elements written. If there is not enough space for all metrics, result is truncated.

get_slot_metrics()

void roc::pipeline::SenderSession::get_slot_metrics

(

SenderSlotMetrics &

slot_metrics

)

const

Get slot metrics.

Remarks

These metrics are for the whole slot. For metrics for specific participant, see get_participant_metrics().

is_valid()

bool roc::pipeline::SenderSession::is_valid

(

)

const

Check if the session was succefully constructed.

refresh()

core::nanoseconds_t roc::pipeline::SenderSession::refresh

(

core::nanoseconds_t

current_time

)

Refresh pipeline according to current time.

Returns

deadline (absolute time) when refresh should be invoked again if there are no frames

route_packet()

status::StatusCode roc::pipeline::SenderSession::route_packet	(	const packet::PacketPtr &	packet,
		core::nanoseconds_t	current_time
	)

Route a packet to the session.

Remarks

This way feedback packets from receiver reach sender pipeline. Packets are stored inside internal pipeline queues, and then fetched when frame are passed from frame_writer().
