Blob & video/MP2T

// 自动下载整合后的TS文件
autoDownloadFile(fileDataList, fileName, fileType) {
  // title / tooltip
  this.tips = `ts 碎片整合中，请留意浏览器下载`;
  // 创建一个新的 Blob 对象，并设置文件的 MIME 类型为 `video/MP2T`
  const fileBlob = new Blob(fileDataList, { type: 'video/MP2T' });
  const aLink = document.createElement(`a`);
  aLink.download = `${fileName}.${fileType}`;
  // 生成一个 blob URL 链接
  aLink.href = URL.createObjectURL(fileBlob);
  // CSS 隐藏下载链接
  aLink.style.display = `none`;
  // 插入到 DOM 中
  document.insertAdjacentElement(`beforeend`, aLink);
  // document.body.appendChild(aLink);
  aLink.click();
  aLink.remove();
