@MadeByDouglas does this fix the problem you mentioned?

Also -- I noticed that occasionally the HLS example page gives me a typical "un-autoplay-able" problem Uncaught (in promise) DOMException error on video.play() on Chrome. Any idea why?

As I mentioned #215 (comment) I do plan to resolve this kind of issues altogether (hopefully).
