NVIDIA VIDEO CODEC SDK
A comprehensive set of API including high-performance tools, samples and documentation for hardware accelerated video encode and decode on Windows and Linux.
NVIDIA GPUs contain one or more hardware-based decoder and encoder(s) (separate from the CUDA cores) which provides fully-accelerated hardware-based video decoding and encoding for several popular codecs. With decoding/encoding offloaded, the graphics engine and the CPU are free for other operations.
GPU hardware accelerator engines for video decoding (referred to as NVDEC) and video encoding (referred to as NVENC) support faster than real-time video processing which makes them suitable to be used for transcoding applications, in addition to video playback.

*** Support is codec dependent
NVIDIA GPUs - beginning with the Kepler generation - contain a hardware-based encoder (referred to as NVENC) which provides fully accelerated hardware-based video encoding and is independent of graphics performance. With complete encoding (which is computationally complex) offloaded to NVENC, the graphics engine and the CPU are free for other operations. For example, in a game recording and streaming scenario like streaming to Twitch.tv using Open Broadcaster Software (OBS), encoding being completely offloaded to NVENC makes the graphics engine bandwidth fully available for game rendering. NVENC makes it possible to:
- Encode and stream games and applications at high quality and ultra-low latency without utilizing CPU
- Encode at very high quality for archiving, OTT streaming, web videos
- Encode with ultra-low power consumption per stream (Watts/stream)
Note: The graphs assume:
- Bitrate savings are BD-BR based on PSNR, average across a large variety of content, using FFmpeg
- In all tests, NVENC is fully loaded and is running at the highest clock
- x264 medium and x265 medium setting are considered “reference” for comparing bitrate savings

NVIDIA GPUs contain a hardware-based decoder (referred to as NVDEC) which provides fully-accelerated hardware-based video decoding for several popular codecs. With complete decoding offloaded to NVDEC the graphics engine and the CPU are free for other operations. NVDEC supports much faster than real-time decoding which makes it suitable to be used for transcoding applications, in addition to video playback applications.
NVDECODE API enables software developers to configure this dedicated hardware video decoder. This dedicated accelerator supports hardware-accelerated decoding of the following video codecs on Windows and Linux platforms: MPEG-2, VC-1, H.264 (AVCHD), H.265 (HEVC), VP8, VP9 (see table below for codec support for each GPU generation).
