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 localRTCInboundRtpStreamStats
object which shares the same Synchronization Source (SSRC). remoteTimestamp
- A
DOMHighResTimeStamp
specifying the timestamp (on the remote device) at which the statistics in theRTCRemoteOutboundRtpStreamStats
object were sent by the remote endpoint. This is different from thetimestamp
found in the baseRTCStats
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).
