RTCInboundRtpStreamStats: totalInterFrameDelay property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

ThetotalInterFrameDelay property of theRTCInboundRtpStreamStats dictionary indicates the total accumulated time between consecutively rendered frames, in seconds.It is recorded after each frame is rendered.

The inter-frame delay variance can be calculated fromtotalInterFrameDelay,totalSquaredInterFrameDelay , andframesRendered according to the formula:(totalSquaredInterFrameDelay - totalInterFrameDelay^2/ framesRendered)/framesRendered.

Note:The property is undefined for audio streams.
