I’m trying to get some statistics/information on the network quality of incoming WebRTC streams, like packets/frames lost, retransmission count, anything that’s available would be helpful. I’ve discovered (with IDE autocomplete magic) that there is a setLossNotifier method in the WebRTCSession but…

I’ve just tried the RTPSession.getIOPerformanceCounter() method, to get some statistics. While the getMessagesInBytes() and getMessagesInCount() (and rates) works as expected in the performance counter, the getMessagesLossCount() and getMessagesLossBytes() methods (and rates) consistently return 0.

Once you have ‘enable webrtc queries’ enabled in Streaming Engine, these are the java method calls to query only webRTC streams. The query check box on engine manager allows you to send the queryAll message over the websocket to an application List<RTPSession> getWebRTCSessions() List<RTPSession> …

This is not exactly what I’m looking for. The REST API linked (incomingstreams) only reports bytes in/out and byterate in/out. This information is also available from RTPSession.getIOPerformanceCounter() Java API, but what I’m looking for is some kind of quality feedback, like number of packages lo…

I see and can understand the need for that. I did check with tech support to confirm for you and this is what I was told: "There is this property (logPacketLoss) [image] Set up WebRTC streaming with Wowza Streaming Engine Learn how to stream WebRTC with Wowza Streaming Engine. …

Looks like I’ve overlooked the logPacketLoss flag. So here is my evaluation result: setting logPacketLoss=true and useNack=true (with useNack=false nothing happens), I see some activity. First there are WARN entries in the Wowza log: WARN server comment - JitterBuffer.packetLoss[s/_definst_/publis…

Best way to capture this is where it happens: in the browser. Using WebRTC’s getStats you can collect any metric you like, such as Nack count, packet loss, bitrate etc. What we do is simply collect all of this during a stream and feed it into our logging/monitoring system. During a WebRTC session,…

Thanks so much Remy. @robymus Remy is one of the webrtc experts I was referring to who is typically more available in our slack channel.
