title: Ionic 3 - Play video downloaded from site and stored on device dataDirectory
body: <p>I just want to ask if what might be the solution on my problem.
  I have a video file on my API server, and when I request, it returns the path of my video. My code successfully copied and downloaded the video. But when I try to make the <code>file.dataDirectory + filename</code> as the source to my video tag, it ain't playing.</p>
  
  <p>Any help would be much appreciated.</p>
