title: How to detect if MP4 file is audio or video with fineuploader or javascript?
body: <p>I am using fineuploader and I allow user to upload audio and video files but I'm facing an issue with MP4 files, I've different video players for both audio and video so I need to track if file is uploading was audio or video so I can save them in their particular folder and play with their specific player.</p>
  
  <p>I would prefer if someone can give solution with javascript or fineuploader core functions but php solution will also works.</p>
  
  <p>PS : I just need a way to do this, rest I'll take care</p>
  
  <p>Thanks</p>
