Proceed to the next video of the custom post type but remain on the same post

So I have a custom post type in WordPress that displays html5 videos. Is there a way I could automatically play the next video once it’s over and still remain on the same post? I’m thinking something like this would be the perfect example.

Here’s a link to what I have so far.

I have a custom post type called nowthisearth_post and a custom field nowthisearth_media_url that is pulling in the link to the MP4 file. Right now there are 6 posts and would like for it to proceed to the next one after the video ends. Here’s what I have right now..

I started off using the get_next_post(); function but it doesn’t seem to work. I’m thinking maybe it would need to be converted into some sort of video playlist with thumbnails at the bottom.

<div class="container-fluid nowthis-header"> <div class="container" style="z-index:11;">     <div class="row">         <div class="col-12">             <?php $  mrssfeed_url = get_post_meta(get_the_id(), 'nowthisearth_media_url', true);?>             <video class="nowthis-video" style="" width="1280" height="720" autoplay="true" controls loop>               <source src="<?php echo $  mrssfeed_url ?>" type="video/mp4">                 Your browser does not support the video tag.             </video>         </div>         <div class="col-12">             <?php $  next_post = get_next_post();             if ( is_a( $  next_post , 'nowthisearth_post' ) ) : ?>                 <a href="<?php echo get_permalink( $  next_post->ID ); ?>"><?php echo get_the_title( $  next_post->ID ); ?></a>             <?php endif; ?>         </div>     </div> </div>
