GT2xx and newer GPUs can additionally decode ASP (divx/xvid/mpeg4).Defines an API for GPU-accelerated decode of MPEG-1, MPEG-2, WMV, H.264, and VC-1 bitstreams.That support the API, extensive documentation is available. In addition to updated NVIDIA binary drivers or the open source ATI/AMD driver It in essence provides what PureVideo/DirectX Video Acceleration is on the Windows platform. It lets any Linux, Solaris, and FreeBSD system play files, including highly complex H.264 formats produced by the Hauppauge HD-PVR, that would otherwise require a high-end multicore CPU. VDPAU (Video Decode and Presentation API for Unix) lets Nvidia and AMD/ATI uvd cards play video with hardware acceleration. 4.2.1.1 Disabling the Composite Extension.
