Detailed Description

A class of objects representing remote participants (RTP applications) in a multimedia session.

Any RTP socket/queue class that directly or indirectly inherits from QueueRTCPManager (and hence has RTCP support) will represent participants from which any RTP or RTCP packet has been received through a Participant object. These Participant objects are entities such as end systems (user applications, monitors, etc), RTP mixers and RTP translators.

Participant objects are identified by a CNAME and provide access to all known data about the source of RTP/RTCP packets, such as the CNAME and any other SDES item. Each participant object is related to one or more synchronization objects (

See Also

SyncSource).

If an RTP application based on ccRTP receives packets from itself (for instance, it is included in the destination list), there will be a Participant object that corresponds to the "local participant" (RTPApplication) object.

Todo:

implement reference counting from sources, so that when a source is destroyed, we know if the Participant should be destroyed.

inherited

Definition at line 99 of file source.cpp.

const std::string& Participant::getPRIVPrefix ( ) const

inline

Get the prefix value for the PRIV SDES item.

Returns

PRIV SDES item prefix as a string.

Return values

empty

string when no PRIV SDES item has been received from this source.

const std::string& Participant::getSDESItem ( SDESItemType  type ) const

inline

Get the value of an SDES item.

For instance, getSDESItem(SDESItemTypeCNAME), return the CNAME of this Participant.

Parameters

type	type of SDES item to get value of.

Returns

value of the SDES item as a string.

Return values

empty

string when the value is not known (no RTCP packet with the requested SDES item has been received from this source).
