The RTCRtpReceiver
method getStats()
asynchronously requests an RTCStatsReport
object which provides statistics about incoming traffic on the owning RTCPeerConnection
, returning a Promise
whose fulfillment handler will be called once the results are available.
Syntax
var promise = RTCRtpReceiver.getStats();
Return value
A JavaScript Promise
which is fulfilled once the statistics are available. The promise's fulfillment handler receives as a parameter a RTCStatsReport
object containing the collected statistics.
The returned statistics include those from all streams which are coming in through the RTCRtpReceiver
, as well as any of their dependencies.
Example
This simple example obtains the statistics for an RTCRtpReceiver
and updates an element's innerText
to display the number of packets lost.
receiver.getStats().then(function(stats) { document.getElementById("lostpackets").innerText = stats.packetsLost; });
