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.

Sorry for not mentioning Intel or Imagination. But my comments apply. Gallium is not a hardware interface anyway. I believe in simple standardized 2D accelerated framebuffers and standardized accelerator cards. So I can buy them like a USB/IEEE1394/PATA PCI/PCIexpress cards and add to my whatever system. The lockin kills small businesses, kills small OSes like Syllable/Haiku, kills research (like Genode/Fiasco) and kills the fun of computing. One standard driver for all framebuffers, one driver for opencl accelerator cards, one driver for all sound cards and so on that should encapsulate standards. This is what I require as a consumer.
