video in gallery not displaying on tablets or mobile devices

Hello,

Apple and Android do not allow autoplay for HTML5 Videos/Audio to prevent unsolicited usage of Bandwidth (which can be Cellular) on the User’s Mobile Device. They can only be played on their native Video Player.

Here is the Official Reference for Apple: https://developer.apple.com/library/safari/documentation/AudioVideo/Conceptual/Using_HTML5_Audio_Video/Device-SpecificConsiderations/Device-SpecificConsiderations.html .

Meanwhile, currently, the Inline Video Autoplay is supported only from iOS 10 onwards. You can use the following instructions to make it work on iOS 10 or above devices:

1. Add the playsinline Attribute to the <video> Tag. Example:
   [ch_pre]<video id="slide-video" poster="images/videos/explore-poster.jpg" preload="auto" loop autoplay muted playsinline>
   ...
   </video>[/ch_pre]

2. Then add the .no-placeholder Class to the .video-wrap Container that encloses the <video> Tag. Example:
   [ch_pre]<div class="video-wrap no-placeholder">
   <video poster="images/videos/explore-poster.jpg" preload="auto" loop autoplay muted playsinline>
   ...
   
   </video>
   <div class="video-overlay" style="background-color: rgba(0,0,0,0.55);"></div>
   </div>[/ch_pre]

This should definitely work fine. Hope this Helps!
