broadcast

broadcast

broadcast is a Pion WebRTC application that demonstrates how to broadcast a video to many peers, while only requiring the broadcaster to upload once.

This could serve as the building block to building conferencing software, and other applications where publishers are bandwidth constrained.

Instructions

Download broadcast

go get github.com/pion/webrtc/v2/examples/broadcast

Open broadcast example page

jsfiddle.net You should see two buttons 'Publish a Broadcast' and 'Join a Broadcast'

Run Broadcast

Linux/macOS

Run broadcast OR run main.go in github.com/pion/webrtc/examples/broadcast

Start a publisher

• Click Publish a Broadcast
• curl localhost:8080/sdp -d "YOUR SDP". The broadcast application will respond with an offer, paste this into the second input field. Then press Start Session

Join the broadcast

• Click Join a Broadcast
• curl localhost:8080/sdp -d "YOUR SDP". The broadcast application will respond with an offer, paste this into the second input field. Then press Start Session

You can change the listening port using -port 8011

You can Join the broadcast as many times as you want. The broadcast Golang application is relaying all traffic, so your browser only has to upload once.

Congrats, you have used Pion WebRTC! Now start building something cool
