Layerslider video not playing in Chrome

I have a Layerslider with just one video that’s set to autoplay on the homepage. It works fine in Safari and Firefox but in Chrome it’s not playing or sizing correctly. I’m getting two errors:

Error 1:
Uncaught TypeError: Cannot read property ‘ready’ of undefined
at l (slideshow-video.js?ver=4.9.6:527)

Error 2:
