RTCRemoteOutboundRtpStreamStats

The WebRTC statistics model's RTCRemoteOutboundRtpStreamStats dictionary extends the underlying RTCSentRtpStreamStats dictionary with properties measuring metrics specific to outgoing RTP streams.

Properties

In addition to the properties defined by RTCSentRtpStreamStats and its underlying RTCRtpStreamstats and RTCStats dictionaries, RTCRemoteOutboundRtpStreamStats defines the following properties.

localId
A DOMString which is used to find the local RTCInboundRtpStreamStats object which shares the same Synchronization Source (SSRC).
remoteTimestamp
A DOMHighResTimeStamp specifying the timestamp (on the remote device) at which the statistics in the RTCRemoteOutboundRtpStreamStats object were sent by the remote endpoint. This is different from the timestamp found in the base RTCStats dictionary; it represents the time at which the object's statistics were received or generated by the local endpoint.
reportsSent
An integer value indicating the total number of RTCP Sender Report (SR) blocks that this SSRC has sent.

Usage notes

The RTCRemoteOutboundRtpStreamStats object's remoteTimestamp proeprty provides statistics based on the received data's NTP timestamp taken from an RTCP Sender Report (SR) block. Be aware that the remote clock may not be synchronized with the local clock (either in current time or speed at which time elapses).
