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. Operating system support 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 d ...

Nouveau (software)
nouveau () is a free and open-source graphics device driver for Nvidia video cards and the Tegra family of SoCs written by independent software engineers, with minor help from Nvidia employees. The project's goal is to create an open source driver by reverse engineering Nvidia's proprietary Linux drivers. It is managed by the X.Org Foundation, hosted by freedesktop.org, and is distributed as part of Mesa 3D. The project was initially based on the 2D-only free and open-source "nv" driver, which Red Hat developer Matthew Garrett and others claim had been obfuscated. nouveau is licensed under the MIT License. The name of the project comes from the French word ''nouveau'', meaning ''new''. It was suggested by the original author, Stéphane Marchesin, after his IRC client's French-language autocorrect system offered the word "nouveau" as a correction for the letters "nv". Software architecture nouveau is a Gallium3D-style device driver and works on top of the Direct Renderin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nvidia NVDEC
Nvidia NVDEC (formerly known as NVCUVID) is a feature in its graphics cards that performs video decoding, offloading this compute-intensive task from the CPU. It is accompanied by NVENC for video ''encoding'' in Nvidia's Video Codec SDK. Technology NVDEC can offload video decoding to full fixed-function decoding hardware (Nvidia PureVideo), or (partially) decode via CUDA software running on the GPU, if fixed-function hardware is not available. Depending on the GPU architecture, the following codecs are supported: * MPEG-2 * VC-1 * H.264 (AVC) * H.265 (HEVC) * VP8 * VP9 * AV1 Versions NVCUVID was originally distributed as part of the Nvidia CUDA Toolkit. Later, it was renamed to NVDEC and moved to the Nvidia Video Codec SDK. Operating system support NVDEC is available for Windows and Linux operating systems. As NVDEC is a proprietary API (as opposed to the open-source VDPAU API), it is only supported by the proprietary Nvidia driver on Linux. Application and library s ...

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. DXVA 2.0 allows more operations, including video capturing and processing operations, to be hardware-accelerated as well. DXVA works in conjunction with the video rendering model used by the video card. DXVA 1.0, which was introduced as a standardized API with Windows 2000 and is currently available on Windows 98 or later, can use either the overlay rendering mode or VMR 7/9. DXVA 2.0, available only on Windows Vista, Windows 7, Windows 8 and later OSs, integrates with Media Foundation (MF) and uses the Enhanced Video Renderer (EVR) present in MF. Overview The DXVA is used by software video decoders to define a codec-specific pipeline for hardware-accelerated decoding and ren ...

Nvidia NVENC
Nvidia NVENC (short for Nvidia Encoder) is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU to a dedicated part of the GPU. It was introduced with the Kepler-based GeForce 600 series in March 2012. The encoder is supported in many livestreaming and recording programs, such as vMix, Wirecast, Open Broadcaster Software (OBS) and Bandicam, as well as video editing apps, such as Adobe Premiere Pro or DaVinci Resolve. It also works with Share game capture, which is included in Nvidia's GeForce Experience software. Consumer targeted GeForce graphics cards officially support no more than 3 simultaneously encoding video streams, regardless of the count of the cards installed, but this restriction can be circumvented on Linux and Windows systems by applying an unofficial patch to the drivers. Doing so also unlocks ''NVIDIA Frame Buffer Capture (NVFBC)'', a fast desktop capture API that uses the capabilities of the GP ...

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 comp, iDCT, and VLD ("Variable-Length Decoding", more commonly known as "slice level acceleration") for not only MPEG-2 but also MPEG-4 ASP video on VIA Unichrome (S3 Graphics Chrome Series) hardware. XvMC was the first UNIX equivalent of the Microsoft Windows DirectX Video Acceleration (DxVA) API. Popular software applications known to take advantage of XvMC include MPlayer, MythTV, and xine.
