Your environment.

• Version: 68545cc
• Client: github.com/pion/webrtc
• Environement: Docker
• Are you using a TURN server? no
• Other Information - stacktraces, webrtc dumps, related issues, suggestions how to fix, links for us to have context

What did you do?

Try to connect to SFU with a webrtc.Peerconnection, like example code here

What did you expect?

It should connect

What happened?

Unsupported media engine

Cause

I found that the name of media engines in pion/ion-sfu is lowercase: code here

In pion/webrtc however, name of media engines is uppercase: code here

So when I use the code like the example in pion/webrtc, it doesn't work

Also I found the test code in pion/ion-sfu is not the same as the example in pion/webrtc: test code here and example code here

It is not a serious bug but takes me several hours. So why not use the same case?

[Olivier Roques]

I ran into the same issue. There must be an issue with the way the SDP is parsed as pion/webrtc explicitly states that "Matching should be case insensitive."
