Nvidia NVDEC

Nvidia NVDEC (formerly known as NVCUVID[1]) is a feature in its graphics cards that performs video decoding, offloading this compute-intensive task from the CPU.[2]

It is accompanied by NVENC for video encoding in Nvidia's Video Codec SDK.[2]

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.[2][3]

Depending on the GPU architecture, the following codecs are supported:[4]

Versions

NVCUVID was originally distributed as part of the Nvidia CUDA Toolkit.[3] Later, it was renamed to NVDEC and moved to the Nvidia Video Codec SDK.[1]

Operating system support
See also: Nvidia PureVideo

NVDEC is available for Windows and Linux operating systems.[2] 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 support
gollark: Am what?
gollark: So do you have anything against my less ambiguous version, or···?
gollark: ···
gollark: - you should tell people when you find some information on them, not then decide to go hunting for yet more information and not telling them in the meantime- you should stop gathering data on them when they ask you to, and not try and deliberately stop them from knowing you're doing it
gollark: Fine, I'll try and restate my views less ambiguously.
