(Redirected from Nvidia NVDEC)

NVDEC (formerly known as NVCUVID^[1]) is a feature in Nvidia graphics cards that performs video decoding, offloading this compute-intensive task from the CPU.^[2] NVDEC is a successor of PureVideo and is available in Kepler and later Nvidia GPUs.

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]

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.^[3] Later, it was renamed to NVDEC and moved to the Nvidia Video Codec SDK.^[1]

Operating system support

Application and library support

Gstreamer has supported NVDEC since 2017.^[5]
FFmpeg has supported NVDEC since 2017.^[6]
mpv has supported NVDEC since 2017 by the use of FFmpeg.^[7]

GPU support

Hardware accelerated decode and encode are supported on Nvidia GeForce, Quadro, Tesla, and GRID products with Fermi or newer generation GPUs.^[8]
