[dependabot]

Bumps github.com/pion/webrtc/v3 from 3.0.0-20200721060053-ca3cc9d940bc to 3.0.15.

Release notes

Sourced from github.com/pion/webrtc/v3's releases.

Future Shock

The Pion team is very excited to announce the v3.0.0 release of Pion WebRTC. Pion WebRTC is a Go implementation of WebRTC. If you haven't used it before check out awesome-pion or example-webrtc-applications for what people are doing. We maintain a feature list and other helpful resources in our README.md

This release includes 264 commits from 43 authors. We reduced sharp edges in the media API, add performance gains in media and datachannel paths and brought ourselves more in alignment with the browser API.

We do have quite a few breaking changes. Please read them carefully, most of these things can't be caught at compile time. Reading this document could save a lot of time debugging. Each change will have a linked commit. Looking at examples/ in the linked commit should show what code you need to change in your application.

Breaking Changes

Trickle ICE is now enabled by default

Before /v3 Pion WebRTC would gather all candidates before a CreateOffer or CreateAnswer generated a SDP. This would cause a few issues in real world applications. You can read about the benefits of Trickle ICE here

• Longer call connection times since we blocked for STUN/TURN even if not needed
• This didn't comply with the WebRTC spec
• Made it harder for users to filter/process ICE Candidates

Now you should exchange ICE Candidates that are pushed via the OnICECandidate callback.

Before

  peerConnection, _ := webrtc.NewPeerConnection(webrtc.Configuration{})
offer, _ := peerConnection.CreateOffer()
peerConnection.SetLocalDescription(offer)
// Send offer to remote peer
websocket.Write(offer)

After

  peerConnection, _ := webrtc.NewPeerConnection(webrtc.Configuration{})
// Set ICE Candidate handler. As soon as a PeerConnection has gathered a candidate
// send it to the other peer
peerConnection.OnICECandidate(func(i *webrtc.ICECandidate) {
// Send ICE Candidate via Websocket/HTTP/$X to remote peer
})
// Listen for ICE Candidates from the remote peer
peerConnection.AddICECandidate(remoteCandidate)
// You still signal like before, but CreateOffer will be much faster
offer, _ := peerConnection.CreateOffer()
peerConnection.SetLocalDescription(offer)
// Send offer to remote peer
websocket.Write(offer)
