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
- Paste the SessionDescription into a file.
- 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.
