Getting InboundRTPStreamStats values from peerConnection.GetStats()

[asmdv]

Hi,

I'm trying to get general stats for my WebRTC application, including received bytes, packet loss, delay, etc. I wrote a small function to check if I can access this information:

func getInboundRTPStreamStats(peerConnection *webrtc.PeerConnection) {
	stats := peerConnection.GetStats()
	for k, stat := range stats {
		log.Infof("Stats %v :: %v\n", k, stats)
		if inboundStat, ok := stat.(webrtc.InboundRTPStreamStats); ok {
			log.Infof("Bytes Received: %d, Packets Lost: %d\n",
				inboundStat.BytesReceived, inboundStat.PacketsLost)
		}
	}
}

I run it inside peerConnection.OnTrack:

peerConnection.OnTrack(func(t *webrtc.TrackRemote, receiver *webrtc.RTPReceiver) {
// ...
go func() {
	for {
		time.Sleep(1 * time.Second)
		getInboundRTPStreamStats(peerConnection)
	}
}()
// ...
}

While I do receive some stats, I am not getting webrtc.InboundRTPStreamStats. I wonder what the issue might be.

I would appreciate any help on this!

Hi @asmdv

I think the issue is you need to use the stats interceptor like this example

We should work on getting this all under one API. The issue is that we have tried to put all our RTP subsystems in the interceptor repo and created some complexity here.

Sorry about that!
