视频P2P加速创建

// 创建RTCPeerConnection对象
const peerConnection = new RTCPeerConnection();

// 添加媒体流
navigator.mediaDevices.getUserMedia({ video: true, audio: true })
  .then(stream => {
    stream.getTracks().forEach(track => peerConnection.addTrack(track, stream));
  });

// 设置ICE候选者
peerConnection.onicecandidate = event => {
  if (event.candidate) {
    // 发送ICE候选者到对端
  }
};

// 接收远程流
peerConnection.ontrack = event => {
  const remoteVideo = document.getElementById('remoteVideo');
  remoteVideo.srcObject = event.streams[0];
};

// 创建Offer并发送
peerConnection.createOffer()
  .then(offer => peerConnection.setLocalDescription(offer))
  .then(() => {
    // 发送Offer到对端
  });

// 接收Offer并创建Answer
function handleOffer(offer) {
  peerConnection.setRemoteDescription(new RTCSessionDescription(offer));
  return peerConnection.createAnswer()
    .then(answer => peerConnection.setLocalDescription(answer))
    .then(() => {
      // 发送Answer到对端
    });
}

// 处理ICE候选者
function handleIceCandidate(candidate) {
  peerConnection.addIceCandidate(new RTCIceCandidate(candidate));
}
