yall.js | A fast , flexible , and small SEO-friendly lazy loader | Search Engine Optimization library

I'm using yall.js to lazy load videos. It works as it should. However I want to add in a loading animation that will sit above the video until it starts playing, so that on slow connection you'll get the first frame and a little loading animation.

I can get the function to work for a singular video, but I want it to work for all videos automatically and individually as other pages will have more videos and I want to have a universal usable code for each page.

I'm using .each to detect all the videos which it seems to, but then I want to refer to each iteration to run code against those individual elements, but It's not working for me.
