Nvidia PureVideo
PureVideo is the Nvidia's hardware SIP core that performs video decoding. PureVideo is integrated into some of the Nvidia GPUs, and it supports hardware decoding of multiple video codec standards: MPEG-2, VC-1, H.264, and HEVC. PureVideo occupies a considerable amount of a GPU's die surface and should not be confused with Nvidia NVENC.〔http://www.pcper.com/reviews/Graphics-Cards/NVIDIA-GT200-Revealed-GeForce-GTX-280-and-GTX-260-Review/NVIDIA-GT200-Archite〕
== Operating system support ==
The PureVideo SIP core needs to be supported by the device driver, which provides one or more interfaces such as VDPAU, VAAPI or DXVA. One of these interfaces is then used by end-user software, for example VLC media player or GStreamer, to access the PureVideo hardware and make use of it.
Nvidia's proprietary device driver is available for multiple operating systems and support for PureVideo has been added to it. Additionally, a free device driver is available, which also supports the PureVideo hardware.
