> HTML5 video was noticeably faster and higher quality on day 1 and Flash never caught up on performance.. Flash video was never perceptibly slower than html per se. The only thing that really affects video performance is whether or not it's hardware accelerated, and in cases where flash used HW it performed the same as html. The reason it seemed slower is that AFAIK there's never been an HTML video implementation th…
Hardware acceleration is a broad term used to describe different things and implementation quality still matters (i.e. does it do everything from format decoding to color conversion, scaling, compositing, etc. and are any individual steps combined?). Every time I've done that comparison, Flash has used significantly more CPU for the same file. It's possible that they've finally managed to get close on the right combi…
But I'd have to quibble with saying flash was never better than native playback - presumably so for raw performance, but that wasn't the goal. Flash video was never great for being technically superior, it was great for cutting the Gordian knot that was the codec problem (and indeed one presumes technical tradeoffs had to be made to that end).
