HTML5 video not autoplaying from javascript

Question

I have an html5 video I am using javascript to load and play but since using this method the video will not autoplay. If I do not load and start using javascript the video doesn't always load it seems to be a 50/50 chance whether or not it is a black screen or it actually loads. Is there a way to autoplay from javascript?

 $(document).ready(function() { var video = document.getElementById('video'); var mp4 = document.getElementById('mp4'); mp4.src = 'promo2.mp4'; video.load(); video.play(); }); 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div id="divVideo" style="margin-top:30px;"> <video id="video" controls autoplay width="560"> <source id="mp4" type="video/mp4" /> </video> </div> 

Answer 1

I believe that Chrome has blocked auto-playing videos from javascript, or at least has blocked auto-playing videos with audio. Try muting the video and then autoplay it. Add these HTML tags to the video element.

Set autoplay property to true in your javascript.

See the Snippet below:

 $( document ).ready(function() { var video = document.getElementById('video'); var mp4 = document.getElementById('mp4'); mp4.src = 'https://sample-videos.com/video123/mp4/720/big_buck_bunny_720p_10mb.mp4'; video.autoplay = true; video.load(); }); 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div id="divVideo" style="margin-top:30px;"> <video id="video" controls autoplay width="560"> <source id="mp4" type="video/mp4" /> </video> </div>
