RTCInboundRtpStreamStats: remoteId property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The remoteId property of the RTCInboundRtpStreamStats dictionary specifies the id of the RTCRemoteOutboundRtpStreamStats object representing the remote peer's RTCRtpSender which is sending the media to the local peer.
