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 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.
2. 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.
