The captions button isn't modal, it doesn't indicate if captions are on or off.
Accessibility-wise this isn't very good. Heck, even from a usability standpoint: no tooltips if I don't understand a button? Why? Those circular arrows might mean repeat (do they?), but all I know is clicking them restarts the music. If I hover, I'm not told what it should be doing. There aren't even alt= attributes or titles somewhere for screen readers... except for a useless aria-label ("undefined, Video demo").
Hey there, thanks for the feedback! Good points. I agree, the captions and restart icons do need some work. Easy fix that I can do pretty quickly.
With regards to the tooltips, currently there are hidden labels which are read out by screen readers. If you view the rendered source, you'll see some spans with "sr-only" classes which contain labels that get read out by the likes of voiceover, etc. An option to show these as tooltips would be a good idea though.
