How to get peer connections statistics

[ghost]

Hi.

Haven't found any info about getStats usage. Could you help me, how to correctly call getStats method in peer connection?

Thanks.

Hi.
We are still based on Chrome's implementation of getStats.
The prototype is: PC::getStats(successCallback);

For example
peerConnection.getStats(function(stats) {
var results = stats.result();
...
});

We used to have an example here: https://github.com/Temasys/Google-WebRTC-Samples/tree/master/samples/web/content/munge-sdp-stats
I'm not sure it is quite up to date though.

Hi,

I played a bit with the statistics and it seems to me that I can only see the statistics from the received video track. In my application, I'm running a p2p session between 2 users.

Here is the stat object we get:

{ Timestamp: "1438100065133.217"
bytesReceived: "1565969"
googCaptureStartNtpTimeMs: "3647088844748"

Thanks for help.
