HTML5 Video Autoplay not working correctly

Question

I'm using this code:

<video width="440px" loop="true" autoplay="true" controls>
<source src="http://www.example.com/CorporateVideo.mp4" type="video/mp4" />
<source src="http://www.example.com/CorporateVideo.ogv" type="video/ogv" />
<source src="http://www.example.com/CorporateVideo.webm" type="video/webm" />
</video>

I want the video to autoplay but when the page loads the video doesn't play. It looks like it's a buffering issue, as when I hover on the video (to show controls) the video is always 2 seconds in but then stops and doesn't continue.

Note: I just visited the site again and autoplay seemed to work, but when I try again the same issue is happening, is this a buffering issue? Anything I can do to stop this?

Answer 1

Try autoplay="autoplay" instead of the "true" value. That's the documented way to enable autoplay. That sounds weirdly redundant, I know.

Answer 2

Chrome does not allow autoplay if the video is not muted. Try using this:

<video width="440px" loop="true" autoplay="autoplay" controls muted>
  <source src="http://www.tuscorlloyds.com/CorporateVideo.mp4" type="video/mp4" />
  <source src="http://www.tuscorlloyds.com/CorporateVideo.ogv" type="video/ogv" />
  <source src="http://www.tuscorlloyds.com/CorporateVideo.webm" type="video/webm" />
</video>

Answer 3

Mobile browsers generally ignore this attribute to prevent consuming data until user explicitly starts the download.

UPDATE: newer version of mobile browser on Android and iOS do support autoplay function. But it only works if the video is muted or has no audio channel:

Answer 4

Working solution October 2018, for videos including audio channel

 $(document).ready(function() {
     $('video').prop('muted',true).play()
 });

html {
  padding: 20px 0;
  background-color: #efefef;
}

body {
  width: 400px;
  padding: 40px;
  margin: 0 auto;
  background: #fff;
  box-shadow: 1px 1px 5px rgba(0, 0, 0, 0.5);
}

video {
  width: 400px;
  display: block;
}

<video onloadeddata="this.play();this.muted=false;" poster="https://durian.blender.org/wp-content/themes/durian/images/void.png" playsinline loop muted controls>
    <source src="http://grochtdreis.de/fuer-jsfiddle/video/sintel_trailer-480.mp4" type="video/mp4" />
    Your browser does not support the video tag or the file format of this video.

You might want to add some scripts if your software doesn't support jQuery or giving any reference type error.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
 <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
//Use above scripts only if the software you are working on doesn't support jQuery.

<script>
      $(document).ready(function() {

//Change the location of your mp3 or any music file. 
        var source = "../Assets/music.mp3";
    
        var audio = new Audio();
        audio.src = source;
        audio.autoplay = true;
      });
    </script>
