如何在webrtc中获取远程视频的宽度和高度

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

// 获取本地媒体流并添加到RTCPeerConnection对象
navigator.mediaDevices.getUserMedia({ video: true, audio: false })
  .then(stream => {
    stream.getTracks().forEach(track => {
      peerConnection.addTrack(track, stream);
    });
  })
  .catch(error => {
    console.error('Error accessing media devices:', error);
  });

// 处理远程媒体流的轨道
peerConnection.ontrack = event => {
  const remoteVideo = document.getElementById('remoteVideo');

  // 获取远程视频轨道并添加到video元素中
  if (event.track.kind === 'video') {
    remoteVideo.srcObject = event.streams[0];
  }
};

// 获取远程视频的宽度和高度
const getRemoteVideoSize = () => {
  const remoteVideo = document.getElementById('remoteVideo');
  const width = remoteVideo.videoWidth;
  const height = remoteVideo.videoHeight;
  console.log('Remote video size:', width, height);
};

// 示例调用获取远程视频尺寸的函数
getRemoteVideoSize();
