Example to show how to swap tracks similar to functionality that might be required by RTPSender.ReplaceTrack.
swap-tracks
swap-tracks demonstrates how to swap multiple incoming tracks on a single outgoing track.
Instructions
Download swap-tracks
go get github.com/pion/webrtc/v2/examples/swap-tracks
Open swap-tracks example page
jsfiddle.net you should see two text-areas and a 'Start Session' button.
Run swap-tracks, with your browsers SessionDescription as stdin
In the jsfiddle the top textarea is your browser, copy that and:
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.
