# stats
stats demonstrates how to use the [webrtc-stats](https://www.w3.org/TR/webrtc-stats/) implementation provided by Pion WebRTC.

This API gives you access to the statistical information about a PeerConnection. This can help you understand what is happening
during a session and why.

## Instructions
### Download stats
```
go install github.com/pion/webrtc/v4/examples/stats@latest
```

### Open stats example page
[jsfiddle.net](https://jsfiddle.net/s179hacu/) you should see your Webcam, two text-areas and two buttons: `Copy browser SDP to clipboard`, `Start Session`.

### Run stats, with your browsers SessionDescription as stdin
In the jsfiddle the top textarea is your browser's Session Description. Press `Copy browser SDP to clipboard` or copy the base64 string manually.
We will use this value in the next step.

#### Linux/macOS
Run `echo $BROWSER_SDP | stats`
#### Windows
1. Paste the SessionDescription into a file.
1. Run `stats < my_file`

### Input stats' SessionDescription into your browser
Copy the text that `stats` just emitted and copy into second text area

### Hit 'Start Session' in jsfiddle
The `stats` program will now print the InboundRTPStreamStats for each incoming stream and Remote IP+Ports.
You will see the following in your console. The exact fields will change as we add more values.

```
Stats for: video/VP8
