Contents. General What is it VDPAU (Video Decode and Presentation API for Unix) lets Nvidia and cards play video with hardware acceleration. It lets any Linux, Solaris, and FreeBSD system play files, including highly complex H.264 formats produced by the, that would otherwise require a high-end multicore CPU. It in essence provides what PureVideo/DirectX Video Acceleration is on the Windows platform. In addition to or the open source ATI/AMD driver that support the API, extensive is available. Some highlights of VDPAU:.
Nvidia 8500 Driver
Defines an API for GPU-accelerated decode of MPEG-1, MPEG-2, WMV, H.264, and VC-1 bitstreams. GT2xx and newer GPUs can additionally decode ASP (divx/xvid/mpeg4). Defines an API for post-processing of decoded video, including temporal and spatial deinterlacing, inverse telecine, and noise reduction. Defines an API for timestamp-based presentation of final video frames. Defines an API for compositing sub-picture, on-screen display, and other UI elements.
Nvidia Geforce 8600 Gt Review
Note that VDPAU does not address content protection issues. Some highlights/limitations of NVIDIA's current implementation:. Supported on NVIDIA GPUs with the NVIDIA second generation video processors (see list further below). Currently, only one video stream can be decoded at a time; NVIDIA hopes to lift this restriction eventually. Supported Cards Nvidia VDPAU is currently supported on the following NVIDIA GPUs (driver version 180.44).
An up-to-date list is available at the Nvidia link given below under 'External Links'. Feature Set, when known, is reflected in parenthesis (A/B/C). See more details regarding and the nvidia driver readme (1) GPUs with this note may not support H.264 streams with the following widths: 49, 54, 59, 64, 113, 118, 123, 128 macroblocks (769-784, 849-864, 929-944, 1009-1024, 1793-1808, 1873-1888, 1953-1968, 2033-2048 pixels).
