In the script below: const pc = new RTCPeerConnection(); pc.createDataChannel("data-channel") pc.setConfiguration({}); await pc.setLocalDescription(); const sdp = pc.localDescription.sdp; sdp should contain a line like "m=application 9 UDP/DTLS/SCTP webrtc-datachannel", but with the GstWebRTC backend that's not true. The line is back in the SDP if pc.setConfiguration({}) is removed.
