Stage Video is key new feature of beta offering

Adobe has launched a new beta version of its Flash Player. The new version is 10.2 beta and it is available on Windows, Linux, and Mac computers right now on Adobe Labs. The new beta includes Stage Video which is a new API that has best in class video playback performance across platforms. The beta also has support for hardware acceleration in IE9.

Other new features include enhanced text rendering, native mouse cursors API along, and support for full screen playback with multiple monitors. Stage Video is one of the most important things in the new beta version and promises to allow websites to deliver smooth video to a number of different devices and access hardware acceleration for the entire video pipeline.

Adobe writes, "Working together with hardware vendors has helped us take advantage of the GPU to offload not only H.264 hardware decoding (introduced in Flash Player 10.1) but the rest of the video rendering pipeline, including color conversion, scaling, and blitting. How efficient is hardware acceleration in Flash Player 10.2 beta? Using Stage Video, we’ve seen laptops play smooth 1080p HD video with just over 0% CPU usage."

Stage video will work with all existing video viewed in Flash Player according to Adobe once the new API is used in the video player SWFs. Adobe notes that YouTube has already started to add early support for Stage Video. Using IE9, Adobe claims that some tests have shown up to 35% improvement in rendering performance. The final release of Flash Player 10.2 is expected for next year.

Adobe notes, "We’ve found the beta to be pretty stable and ready for broad testing, but keep in mind this is a pre-release version of Flash Player, so not everything will be fully baked. If you encounter any issues, please file a bug in our public database so we can investigate. We appreciate your help and feedback."

True if you are an application and not a plugin. None of the browsers were drawing to the screen using anything that would allow a plugin to use that capability so no plugin could use such capability. Quicktime and Mediaplayer are exceptions to this rule though as they aren't built like flash they call to an outside program to display a file. Flash uses the browser exclusively for all drawing calls.

Oh and Flash 10.1 (STABLE) has hardware acceleration. Just not to the level 10.2 is going to have. Maybe your hardware doesn't support it?

Not sure where you got your misinformation, but Flash doesn't exclusively use the browsers rendering/drawing engine. It is a plugin that could "break-out" just a much as QT or WMP could. The reason they kept everything software is because their rendering engine was entirely software based & it would have been hard to integrate effects from an overlay surface with their software rendering engine.

Now they did start offering hardware acceleration, which is not quite the same as what I was talking about. They accelerate the video decoding by doing it on the video card, however that stream is still sent back to Flash's software renderer which is why Intel Atom based systems with nVIDIA ION2 struggle when dealing with HD flash based content, because of the neutered bandwidth on the PCIe 1x connection that ION hooks up to. You also may see higher CPU usage when resizing video to something other than the native resolution of the stream because the resizing is being done by the CPU.
