This is still not working for me outside of Safari on my mac with an image in my footer as the trigger. The trigger is the blue ECFA logo in the middle at the bottom of my site in the footer. I have the image and code in a div to center the logo but have even removed the div and it still doesn't work? I am using a vimeo vid I have tried it from youtube with the same results. If this is a Theme issue then why would it work in Safari? The site is https://www.youthunlimited.org and my code I am using in the footer is as follows:
<div class="ecfa"><img src="/wp-content/uploads/2013/10/ECFA_Web.png"
