从手机上传文件发送应用程序/八位字节流

我有一个简单的视频文件上传表格。它可以在普通PC上运行，但是从移动设备（Android）上传时，它会将文件mime类型作为文件null和错误1 application/octet-stream发送。

我不知道该怎么办。谁能帮忙？

这是表格

<input type="file" id="video_link" name="video[link]" class="form-control" accept="video/*">

以下是在移动设备上提交的视频var_dump

UploadedFile {#9 ▼
  -test: false
  -originalName: "VID-20160712-WA0029.mp4"
  -mimeType: "application/octet-stream"
  -size: 0
  -error: 1
  path: ""
  filename: ""
  basename: ""
  pathname: ""
  extension: ""
  realPath1970: "/app/web"
  aTime: 1970-01-01 00:00:00

  cTime: -01-01 00:00:00
  inode: false
  size: false
  perms: 00
  owner: false
  group: false
  type: false
  writable: false
  readable: false
  executable: false
  file: false
  dir: false
  link: false
}

这是从常规PC浏览器上传的文件转储
