The roadmap includes support of a number of additional video providers: https://github.com/meandavejustice/min-vid/issues/6

Additionally, they're looking at supporting any old HTML5 <video> element: https://github.com/meandavejustice/min-vid/issues/331

The intent is certainly not to be exclusionary; it's just a new, experimental project with a small team.

So why does the playback of html5 video from a site outside the bounds of the page require specific support for the service?

Why wouldn't you just make this play any <video> element in a floating widow and be done with it?
