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.

Member since:

On the OS-software interface side, OpenGL and DirectX are standardized, with relatively infrequent changes.

Why couldn't this happen on the hardware-OS interface side ?

It's not as if GPU vendors innovate so much that they need new standards all the time anyway. From time to time we see a new feature like unified shaders or tesselation, but most of the time it's really just stacking more and more shaders on a single chip and making them run faster.
