DirectX Video Acceleration. DirectX Video Acceleration (DXVA) is a Microsoft API specification for the Microsoft Windows and Xbox 360 platforms that allows video decoding to be hardware-accelerated. The pipeline allows certain CPU -intensive operations such as iDCT, motion compensation and deinterlacing to be offloaded to the GPU.
Video Acceleration API. Video Acceleration API (VA-API) is an open source application programming interface that allows applications such as VLC media player or GStreamer to use hardware video acceleration capabilities, usually provided by the graphics processing unit (GPU). It is implemented by the free and open-source library libva, combined ...
The H.264-decoder no longer suffers the framesize restrictions of VP3, and adds hardware-acceleration for MVC, a H.264 extension used on 3D Blu-ray discs. MVC acceleration is OS dependent: it is fully supported in Microsoft Windows through the Microsoft DXVA and Nvidia CUDA APIs, but is not supported through Nvidia's VDPAU API.
Gary Sullivan (engineer) Gary Joseph Sullivan (born 1960) is an American electrical engineer who led the development of the AVC, HEVC, and VVC video coding standards and created the DirectX Video Acceleration (DXVA) API / DDI video decoding feature of the Microsoft Windows operating system. He is currently Director of Video Research and ...
Support for Quick Sync hardware accelerated decoding of H.264, MPEG-2, and VC-1 video is widely available. One common way to gain access to the technology on Microsoft Windows is by use of the free ffdshow filter. Some other free software like VLC media player (since version 2.1.0 "Rincewind") supports Quick Sync as well.
Unified Video Decoder. Unified Video Decoder (UVD, previously called Universal Video Decoder) is the name given to AMD 's dedicated video decoding ASIC. There are multiple versions implementing a multitude of video codecs, such as H.264 and VC-1. UVD was introduced with the Radeon HD 2000 Series and is integrated into some of AMD's GPUs and ...
Comparison of video codecs. Α video codec is software or a device that provides encoding and decoding for digital video, and which may or may not include the use of video compression and/or decompression. Most codecs are typically implementations of video coding formats. The compression may employ lossy data compression, so that quality ...
VC-1 is an evolution of the conventional block-based motion-compensated hybrid video coding design also found in H.261, MPEG-1 Part 2, H.262/MPEG-2 Part 2, H.263, and MPEG-4 Part 2. It was widely characterized as an alternative to the ITU-T and MPEG video codec standard known as H.264/MPEG-4 AVC. The Advanced Profile of VC-1 contains tools ...
