RTCInboundRtpStreamStats: framesPerSecond property

Limited availability

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

The framesPerSecond property of the RTCInboundRtpStreamStats dictionary indicates the number of frames decoded in the last second.

Note that this may be lower than the media source frame rate, which is provided in RTCVideoSourceStats.framesPerSecond.

Note: The value is undefined for audio streams.
