The getSynchronizationSources()
method of the RTCRtpReceiver
interface returns an array of
RTCRtpContributingSource
instances, each corresponding to one SSRC
(synchronization source) identifier received by the current
RTCRtpReceiver
in the last ten seconds.
Syntax
var rtcRtpContributingSources = rtcRtpReceiver.getContributingSources()
Parameters
None.
Return value
An array of RTCRtpSynchronizationSource
instances. Each instance
describes one of the synchronization sources that provided data to the incoming stream
in the past ten seconds.
As you'll see in the documentarion for RTCRtpSynchronizationSource
, it
inherits the properties of RTCRtpContributingSource
,
including timestamp
, source
,
and audioLevel
.
The synchronization source objects add a
voiceActivityFlag
property, which indicates if the last RTP packet received contained voice activity.
