Nvidia PureVideo

PureVideo is 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, HEVC, and AV1. PureVideo occupies a considerable amount of a GPU's die area and should not be confused with Nvidia NVENC. In addition to video decoding on chip, PureVideo offers features such as edge enhancement, noise reduction, deinterlacing, dynamic contrast enhancement and color enhancement.

The PureVideo SIP core needs to be supported by the device driver, which provides one or more interfaces such as NVDEC, 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.

Support for PureVideo has been available in Nvidia's proprietary driver version 180 since October 2008 through VDPAU. Since April 2013[citation needed] nouveau also supports PureVideo hardware and provides access to it through VDPAU and partly through XvMC.

Microsoft's Windows Media Player, Windows Media Center and modern video players support PureVideo. Nvidia also sells PureVideo decoder software which can be used with media players which use DirectShow. Systems with dual GPU's either need to configure the codec or run the application on the Nvidia GPU to utilize PureVideo. Media players which use LAV, ffdshow or Microsoft Media Foundation codecs are able to utilize PureVideo capabilities.

OS X was sold with Nvidia hardware, so support is probably available.[citation needed]

PureVideo HD (see "naming confusions" below) is a label which identifies Nvidia graphics boards certified for HD DVD and Blu-ray Disc playback, to comply with the requirements for playing Blu-ray/HD DVDs on PC:

The original PureVideo engine was introduced with the GeForce 6 series. Based on the GeForce FX's video-engine (VPE), PureVideo re-used the MPEG-1/MPEG-2 decoding pipeline, and improved the quality of deinterlacing and overlay-resizing. Compatibility with DirectX 9's VMR9 renderer was also improved. Other VPE features, such as the MPEG-1/MPEG-2 decoding pipeline were left unchanged. Nvidia's press material cited hardware acceleration for VC-1 and H.264 video, but these features were not present at launch.
