It would be great to have GPU-assisted video decoding !!!

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 the AMD GPUs and APUs. UVD occupies a considerable amount of the die surface and is not to be confused with AMD's Video Coding Engine (VCE). The UVD is based on an ATI Xilleon video processor, w...

Video Acceleration API

Video Acceleration API (VA API) is a royalty-free API as well as its implementation as free and open-source library (libVA) distributed under the MIT License. The VA API is to be implemented by device drivers to offer end-user software, such as VLC media player or GStreamer, access to available video acceleration hardware, such as PureVideo (through the libva-vdpau driver, which implements VA API in terms of VDPAU) or Unified Video Decoder. The API enables and provides access to hardware-accele...

VDPAU

Video Decode and Presentation API for Unix (VDPAU) is a royalty-free application programming interface (API) as well as its implementation as free and open-source library (libvdpau) distributed under the MIT License. VDPAU is also supported by Nvidia. The VDPAU interface is to be implemented by device drivers, such as Nvidia GeForce driver, nouveau, amdgpu, to offer end-user software, such as VLC media player or GStreamer, a standardized access to available video decompression acceleration hardw...

X-Video Bitstream Acceleration

X-Video Bitstream Acceleration (XvBA), designed by AMD Graphics for its Radeon GPU and Fusion APU, is an arbitrary extension of the X video extension (Xv) for the X Window System on Linux operating-systems. XvBA API allows video programs to offload portions of the video decoding process to the GPU video-hardware. Currently, the portions designed to be offloaded by XvBA onto the GPU are currently motion compensation (MC) and inverse discrete cosine transform (IDCT), and variable-length decoding Xv...

X-Video Motion Compensation

X-Video Motion Compensation (XvMC), is an extension of the X video extension (Xv) for the X Window System. The XvMC API allows video programs to offload portions of the video decoding process to the GPU video-hardware. In theory this process should also reduce bus bandwidth requirements. Currently, the supported portions to be offloaded by XvMC onto the GPU are motion compensation (mo comp) and inverse discrete cosine transform (iDCT) for MPEG-2 video. XvMC also supports offloading decoding of mo...
