I have used the following code to create a video light box.
[image class=“video-lightbox” src=“http://businesscoachcompany.com/wp-content/uploads/2017/12/Business-card-3-BCCo-Dan-Zaleski.jpg” link=“true” href=“http://businesscoachcompany.com/wp-content/uploads/2017/12/Dan-BCCO-promo.mp4?rel=0&autoplay=1” lightbox_video=“true”][lightbox selector=".video-lightbox"]
The video will autoplay on Firefox, but I cannot get it to autoplay in safari. Not sure if there is something wrong with the code.
