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
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
- Gstreamer has supported NVDEC since 2017.[5]
- FFmpeg has supported NVDEC since 2017.[6]
- mpv has supported NVDEC since 2017.[7]
