Hello friend, good job, the server generates the following error once FFMPEG starts:

I think it may be a problem of my HTML client, could you help me with an example of HTML client, thank you very much for your help.

navigator.mediaDevices
    .getUserMedia({
        audio: true,
        video: true,
    })
    .then((cameraStream) => {
        const pc = new RTCPeerConnection({
            sdpSemantics: 'unified-plan',
        });

        cameraStream.getTracks().forEach(track => pc.addTrack(track, cameraStream));

        pc.createOffer()
            .then((offer) => pc.setLocalDescription(offer))
            .then(() =>
                fetch('http://xxx.xxx.xxx.xxx:8090/webrtc/offer', {
                    method: 'POST',
                    headers: { 'Content-Type': 'application/json' },
                    body: JSON.stringify({
                        "ingestionAddress":"xxxxx",
                        "streamKey": "xxxxxxxxx",
                        "offer": JSON.stringify(pc.localDescription)
                    })
                })
            )
            .then((res) => {
                if (!res.ok) throw new Error(`${res.status} ${res.statusText}`);
                return res.json();
            })
            .then((answer) => pc.setRemoteDescription(answer))
            .catch((err) => console.error(err));

Hey @remymatheus, try creating a peer connection with the google stun server like

new RTCPeerConnection({ iceServers: [ { urls: 'stun:stun.l.google.com:19302' } ] });

Also, if both clients (Go and JavaScript) are on separate machines, you would want to either trickle ice or wait until ice gathering is complete before sending the remoteDescription

Hello @remymatheus I am facing the same error in the server. Did you manage to solve that?
