RTCRemoteInboundRtpStreamStats: roundTripTime property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The roundTripTime property of the RTCRemoteInboundRtpStreamStats dictionary indicates the estimated round trip time (RTT) for this synchronization source (SSRC), in seconds.
The round trip time is calculated based on the RTCP timestamps in the RTCP Sender Report (SR), and requires a report with a Delay Since Last SR (DLSR) block that has a value other than 0. The property does not exist until such a report has been received.
Note that the average RTT for the session can be computed by dividing totalRoundTripTime by roundTripTimeMeasurements.
Value
A number indicating the current estimated round trip time, in seconds.
