See the Pen Videogular – Overlay Play Plugin by Two Fucking Developers (@2fdevs) on CodePen.
Overlay play plugin creates a big layer that covers the entire player to allow user to click easily on it. When the video is completed the plugin shows again to allow user start again.
The play icon is a CSS font so you can change by overriding it.
You can install with bower:
bower install videogular-overlay-play
