Linux Efforts to implement NVIDIA's Video Decode and Presentation API for Unix (VDPAU) on the open source Radeon Gallium3D drivers (for AMD/ATI chipsets) are reportedly just beginning to work. Being Gallium3D-based means this new VDPAU state tracker is using GPU shaders and not the dedicated Unified Video Decoding (UVD) engine found on modern Radeon HD graphics processors, but using shaders is still a big performance win for HD video playback compared to pegging the CPU constantly. Also, MPEG-2 is the only codec known to work at this time. Once the basic state tracker functionality works, support for other video codecs, such as VP8 and H264, should be relatively easy to add.

This effort is good only for linux and it hides the fact that there are only 2 players in the GPU industry.

The above work is linux/ati-nvidia lockin and though I love linux this is not something I am very happy.

This should work for any hardware that has a gallium driver for it, and that framework was carefully designed to be portable across hardware and operating systems. Although at the moment, Linux + ATI/NVidia is pretty accurate.
