Add speed buttons to any HTML5 <video> element. Comes with a loader for YouTube and Vimeo
I tested it today and while it's true that the graphical UI isn't showing (I don't have time to track down why this is the case), the keyboard shortcuts still work. For now, I've pushed a patch to address the speed resetting issue.
The keyboard shortcuts are +, -, and * to reset.
doesn't work in 2023
