# swap-tracks
|
|
swap-tracks demonstrates how to swap multiple incoming tracks on a single outgoing track.
|
|
|
|
## Instructions
|
|
### Download swap-tracks
|
|
```
|
|
go install github.com/pion/webrtc/v4/examples/swap-tracks@latest
|
|
```
|
|
|
|
### Open swap-tracks example page
|
|
[jsfiddle.net](https://jsfiddle.net/1rx5on86/) you should see two text-areas and two buttons: `Copy browser SDP to clipboard`, `Start Session`.
|
|
|
|
### Run swap-tracks, 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 | swap-tracks`
|
|
#### Windows
|
|
1. Paste the SessionDescription into a file.
|
|
1. Run `swap-tracks < my_file`
|
|
|
|
### Input swap-tracks's SessionDescription into your browser
|
|
Copy the text that `swap-tracks` just emitted and copy into second text area
|
|
|
|
### Hit 'Start Session' in jsfiddle, enjoy your video!
|
|
Your browser should send streams to Pion, and then a stream will be relayed back, changing every 5 seconds.
