half-hearted attempts to optimize video playback ? the Flash Player plugin can render hardware accelerated video since v10.2 (released early 2011). http://blogs.adobe.com/flashplayer/2011/02/flash-player-10-2-launch.html http://blogs.adobe.com/flashplayer/2011/02/flash-player-10-2... "For example, using Flash Player 10.2 with Stage Video hardware acceleration, we’ve tested a Mac Mini released two years ago and a low-powered GPU-enabled Windows netbook playing smooth full HD 1080p video using less than 8% of the CPU; more powerful computers use even less."

Jobs' original criticism of Flash was in 2010, when HW accel was not yet available. It might've lead Adobe to do it, however.

  Actually h.264 hardware acceleration was introduced in 10.1 mid 2010 and it had a public beta in the months before. It was Windows only with Adobe saying: "Mac OS X does not expose access to the required API" [1]. Apple opened up the hardware API while 10.1 was on the finish line [2] and so the Mac only got support in the next 10.2 release. So another interpretation is: Apple was well aware that smooth video playback was coming to other platforms and Jobs piece (and opening up the acceleration API) was an reaction to that.

> the Flash Player plugin can render hardware accelerated video since v10.2 (released early 2011). I'm aware of that but the quality of the actual implementations still varies widely. I've done the comparison periodically since that was released and their quoted figures have never reproduced on any Flash video player which is actually used on the web (YouTube, Vimeo, jwplayer and a few other open-source projects, the custom players used by various big media companies, etc.). On OS X or Windows XP-8.1, on multiple devices, it's consistently been the same: Flash = fan on high, HTML5 = fans off. Flash's settings show hardware acceleration enabled but there's either a really restrictive hardware check quietly disabling it or absolutely nobody ever managed to ship a player using Stage Video, including the companies quoted in that press release.
