Ionic video player doesn't play videos

i have a problem. my homepage.html is

<div class="embed-responsive embed-responsive-16by9">
<video width="400" autoplay loop class="embed-responsive-item" controls>
  <source src="{{url}}" type="video/mp4">

  });    
}

 stopVideo(){
alert("stop video");

this.videoPlayer.close();
}

My videos path is
so how can i show it on my screen ?

Your video path should be set to /assets/videos/Atiye.mp4" always.

In your videoPlayer.play call, you do not need to use file:/// there.
