Shifting that burden to more general-purpose compute resources would be one step away from moving it back onto the CPU itself, since in both cases you'd be working with a software-based decoder. This is called the 'fixed function decoder.' It lives to decode and it does nothing else. Modern GPUs already have a portion of their design specifically dedicated to decoding and processing video data. There is a lot of image processing that occurs. But there is more to video than just raw data. GPGPU is for processing raw data in a highly parallelized manner. And any requests to add that support are nutty, because it is self-defeating. There is no DirectCompute, no APP, no CUDA. We should make this completely clear: there is no general-purpose GPU computing in Flash Player. All of those still remain CPU-oriented operations. After the H.264 video data is decoded, there is no real GPU assistance in rendering interactive graphics elements, doing color space conversion, or performing scaling on the video itself.

Thus, consistent acceleration with hardware compositing is now available in Flash Player 10.1 on Mac OS X, which takes advantage of Core Animation in browsers that support Core Animation (Safari).ДЄt the end of the day, other operations are still done in software in Flash Player 10.1. In the majority of cases, your content will become slower.' To address the hardware fragmentation problem, Adobe is now relying more on native platform libraries. 'Just because Flash Player is using the video card for rendering does not mean it will be faster. But this was not carried over into Flash Player 10.1 because differences in content and fragmented graphics hardware/driver implementations often negated the gains of doing this in the GPU. This could occur via the GPU using hardware compositing, similar to what we might see in 3D video game.

For instance, imagine an animation where multiple objects and layers (such as grass, trees, and clouds) are all generated as bitmaps that need to be composed as a single image after all the additional vectors undergo rasterization. The hardware compositing that was available in Flash Player 10 was really related more to animations where you have multiple bitmaps and vectors generated in real-time. What about GPU compositing of video with other graphical elements? According to a developer post on Adobe and a recent one-on-one discussion with Adobe, GPU hardware compositing does not occur on Window PCs in Flash Player 10.1.
