Question

I have a button,here on click of the button I want to upload the video file and render one after other on multiple click.Its working fine but I am not able to add controls here,I need to add controls also dynamically. Here is the plunker https://plnkr.co/edit/umHmYGJvT1a8WnVFxXAH?p=preview in which you can upload a video file and render it.but in that html5 video there is no controls.Here is code below.

html

<link rel="stylesheet" href="css/style.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

  <input type="file" id="file1" name="image" accept="video/*" capture style="display:none" />
  <span id="upfile1" style="cursor:pointer">upload button1</span>
</p>
<div id="demo1">

function displayAsImage(file) {
  var imgURL = URL.createObjectURL(file),
    img = document.createElement('video');
  img.onload = function() {
    URL.revokeObjectURL(imgURL);
  }; 
  img.src = imgURL;
  document.getElementById("demo1").appendChild(img);

Use the controls attribute in video tags.

Example:

<video src="" controls></video>
