MediaRecorder API记录有大小限制吗？

let mediaRecorder;
let recordedChunks = [];

// 获取媒体流
navigator.mediaDevices.getUserMedia({ video: true, audio: true })
  .then(stream => {
    mediaRecorder = new MediaRecorder(stream);

    // 当有数据可用时，将其添加到 recordedChunks 数组
    mediaRecorder.ondataavailable = event => {
      if (event.data.size > 0) {
        recordedChunks.push(event.data);
      }
    };

    // 录制结束时触发
    mediaRecorder.onstop = () => {
      const blob = new Blob(recordedChunks, {
        type: 'video/webm'
      });
      const url = URL.createObjectURL(blob);
      const a = document.createElement('a');
      document.body.appendChild(a);
      a.style = 'display: none';
      a.href = url;
      a.download = 'test.webm';
      a.click();
      window.URL.revokeObjectURL(url);
    };

    // 开始录制
    mediaRecorder.start();

    // 录制10秒后停止
    setTimeout(() => {
      mediaRecorder.stop();
    }, 10000);
  })
  .catch(err => {
    console.error('The following error occurred: ' + err.name);
  });
