enum SyncSource::State¶

Synchronization source states during an RTP session. In general, new synchronization sources are not considered valid until multiple valid data packets or a valid RTCP compound packet has been received from the new source (

See also

A valid participant is in stateActive state if RTP and/or RTCP packets are currently being received from it. If, after a small number of RTCP report intervals (see IncomingDataQueue::setSourceExpirationPeriod() ), no packets are received, it will reach the stateInactive state. If, after a small number of RTCP report intervals, no packet is received from an inactive source, it will be deleted.

If RTCP is being used, after receiving a BYE RTCP packet from a synchronization source, it will reach the stateLeaving state and will be deleted after a delay (see QueueRTCPManager::setLeavingDelay()).

Sources in statePrevalid and stateLeaving are not counted for the number of session members estimation.

Enumerator

stateUnknown

No valid packet has been received.

statePrevalid

Some packets have been.

stateActive

received, but source validity not yet guaranteed. We currently receive packets

stateInactive

(data or control) from this source. Was active in the near past but

stateLeaving

no packet from this source has been received lately. An RTCP BYE has been received from the source.
