<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Video Call</title>
</head>
<body>
<video id="localVideo" autoplay muted></video>
<video id="remoteVideo" autoplay></video>
<button id="startButton">Start</button>
<button id="callButton">Call</button>
<button id="hangupButton">Hang Up</button>
<script>
const localVideo = document.getElementById('localVideo');
const remoteVideo = document.getElementById('remoteVideo');
const startButton = document.getElementById('startButton');
const callButton = document.getElementById('callButton');
const hangupButton = document.getElementById('hangupButton');
let localStream;
let remoteStream;
let peerConnection;
const servers = {
iceServers: [
{ urls: 'stun:stun.l.google.com:19302' }
]
};
startButton.onclick = async () => {
localStream = await navigator.mediaDevices.getUserMedia({ video: true, audio: true });
localVideo.srcObject = localStream;
};
callButton.onclick = () => {
peerConnection = new RTCPeerConnection(servers);
peerConnection.onicecandidate = event => {
if (event.candidate) {
// Send the candidate to the remote peer
}
};
peerConnection.ontrack = event => {
remoteVideo.srcObject = event.streams[0];
};
localStream.getTracks().forEach(track => peerConnection.addTrack(track, localStream));
// Create and send an offer to the remote peer
};
hangupButton.onclick = () => {
peerConnection.close();
peerConnection = null;
};
</script>
</body>
