With Safari, the drop of 2 percentage points amounts to 12%, which is nice, but Flash Player 10.2 still trails HTML5-based H.264 playback on that platform. With Flash Player 10.2 (but not 10.1), Flash playback is more efficient than WebM, but it's close. In the Firefox Beta I tested, Flash Player 10.2 reduced CPU requirements by ten percentage points, a reduction of 26%. I know that you can read tables at least as well as I can, so I'll just point out the highlights. Regarding HTML5-based H.264 playback, on the Mac, Safari playing HTML5-based H.264 is slightly more efficient than Flash Player 10.2, as is Internet Explorer 9 in Windows. The Cliff's Notes version is this: In all browsers but Google Chrome, Flash Player 10.2 does substantially reduce the CPU required to display the video, which should mean improved video playback on all platforms that support Flash GPU acceleration.įlash Player 10.2 is more efficient that any implementation of HTML5-based WebM, though it's close on several platforms. Then, just for fun, I tested the CPU requirements for playback via whichever HTML5 codec each browser supported. As an overview, I played back a 720p video from YouTube in a variety of browsers, first with Flash Player 10.1, then 10.2. Specifically, I tested extensively on a MacBook Pro and my Hewlett Packard 8710w notebook, and you can find the notebook specs and procedures here. You can read all about the new announcement here my tests focused on the video acceleration aspect of the announcement. Support for GPU rendering in Microsoft's Internet Explorer 9 browser.Sub-pixel text rendering enhancements that should enhance text readability, especially for complex character-based languages.Added support for custom native mouse cursors.Multiple display full screen support, so you can watch a video in full screen on one display on a multiple monitor workstation.We'll evaluate the performance of Stage Video once it's generally available in YouTube, Vimeo, or similar site). The key thing to note here is that websites need to update their SWF player file to harvest the benefit, but NOT their video library, so re-encoding is NOT required. (Clarification added 2/21/11: The results below don't reflect the potential performance benefit from Stage Video since it was not generally available when we performed these tests. Stage Video, a 'hardware accelerated video pipeline' for more efficient video playback.Adobe released Flash Player 10.2 on February 8 here's a bullet list of the new features:
