AMD Accelerates Adobe® Flash Player 10.1 with ATI Stream Technology
*******************EXCERPT**************************
Adobe and AMD have been working closely together to optimize and dramatically improve video playback performance of Flash Player 10.1 by taking advantage of hardware video acceleration on Windows-based PCs equipped with ATI Stream-enabled GPUs.1
Adobe Flash Player 10.1 introduces hardware-based H.264 video decoding to enable smooth, high quality video with minimal system overhead across mobile devices and PCs.
ATI Stream technology accelerates Adobe® Flash® Player 10.1 on systems equipped with ATI Stream-enabled GPUs to enable high-quality, high definition (HD) video on rich Web content and applications based on Adobes Flash platform. ATI Stream technology enables a balanced approach using both AMD CPUs and GPUs for an amazing experience, including improved video playback, amazing image quality, and reduced CPU utilization.
Users will be able to enjoy a much smoother viewing experience when accessing rich, H.264 video content built with the Adobe Flash Platform from popular sites like Hulu.com or YouTube on systems equipped with ATI Stream-enabled GPUs.
Using ATI Stream technology, owners of ATI Radeon HD 4000 Series graphics cards can accelerate the conversion of standard and HD video into multiple formats for use on various consumer electronics devices. By harnessing the massive parallel processing power of AMD GPUs, transcoding files has never been easier. The free ATI Video Converter2 enables basic GPU transcoding of HD video streams.
For more advanced transcoding functionality CyberLinks MediaShow Espresso video converter application leverages AMDs unique Unified Video Decoder 2 (UVD 2) through its ATI Stream technology to quickly convert digital video files for use on portable devices like Apple iPhone and Sony PSP.
Nvidia may have something like this also...but I know nothing about it.
