That's been known since the talk of html5 video tag started.

It's not so clever given changing implementation of video prefetch logic, and differing codec behaviour with 1 frame videos with hardware decoders.

I knew of few Android devices which claim to be able to do 4k VP9 in hardware, but plainly hang upon playing VP9 from Youtube.

Does Android Chrome do JPEG decoding with hardware these days?

But needs autoplay=true which works less and less. Even with "muted"

I would never use it though, I’m guessing it breaks all default browser image behavior. Drag image from browser to desktop, right click, accessibility, etc.
