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 the Nvidia GeForce driver, nouveau, or amdgpu, to offer end-user software, such as VLC media player or GStreamer, a standardized access to available video decompression acceleration hardware in the form of application-specific integrated circuit (ASIC) blocks on graphics processing units (GPU), such as Nvidia's PureVideo or AMD's Unified Video Decoder and make use of it.

VDPAU is targeted at Unix-like operating systems (including Linux, FreeBSD, and Solaris).
