This ducks the real issue.<p>I'm not all that concerned about the efficiency of the codec and of the mechanism that flushes video to the screen. That said, <video> in a web browser that's codesigned to work on a platform is always going to give a complex cross-platform app like Flash a run for the money.<p>I'm more concerned that Flash burns up CPU for no reason at all. I mean, my Mac Mini hits 100% CPU and sounds like a helicopter taking off when I've got a little tiny flash ad open on any tab. I got no trouble w/ internet ads, but it's ridiculous that one stupid ad should be able to completely disable the power management system on my computer.
The post spends a lot of time talking about flash not utilizing / partially utilizing / fully utilizing graphics cards and makes a lot of conclusions and even takes a dig at apple about it. But then never bothers to ask the same questions about html5. e.g., which browsers are natively using hardware acceleration for H.264, if any? Apparently the author didn't find it relevant. "I didn't contact any other companies because the tests are objective and straightforward."<p>If flash only beats html5 when using hardware acceleration and html5 browsers haven't introduced hardware acceleration yet, his conclusions end up backwards, or at best completely irrelevant and speculative. <i>shrug</i>
Steve Jobs hates flash for a lot of reasons but it is mostly because flash runs faster/better on Windows than on Mac OS. This article quantifies what people who use Mac, Windows and Linux know already: Flash is a hog outside of Windows.
