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

Thanks for your reply.

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?
