The RTCRtpSynchronizationSource
dictionary of the the WebRTC API is used by getSynchronizationSources()
to describe a particular synchronization source (SSRC). A synchronization source is a single source that shares timing and sequence number space. Since RTCRtpSynchronizationSource
implements RTCRtpContributingSource
, its properties are also available.
The information provided is based on the last ten seconds of media received.
While the published specification describes this as an interface, it has since been changed to a dictionary in follow-up drafts.
