The Video Codec SDK includes a complete set of APIs, samples and documentation for hardware accelerated video encode and decode on Windows and Linux.

The SDK consists of two hardware acceleration interfaces: NVENCODE API for video encode acceleration NVDECODE API for video decode acceleration (formerly called NVCUVID API)
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.

Encode


Get NVIDIA Video Codec SDK

If you are looking to make use of the dedicated decoding/encoding hardware on your GPU in an existing application you can leverage the integration already available in the FFmpeg/libav . FFmpeg/libav should be used for evaluation or quick integration, but it may not provide control over every encoder parameter. NVDECODE and NVENCODE APIs should be used for low-level granular control over various encode/decode parameters and if you want to directly tap into the hardware decoder/encoder. This access is available through the Video Codec SDK.


For application users



Cross-platform solution to record, convert and stream audio and video. Includes NVIDIA Video Hardware Acceleration Hardware acceleration for most popular video framework Leverages FFmpeg’s Audio codec, stream muxing, and RTP protocols Available for Windows, Linux You can now use FFMPEG to accelerate video encoding and decoding using NVENC and NVDEC, respectively. Turing support coming soon

Key Features of Video Codec SDK
NVENC - Hardware-Accelerated Video Encoding
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 scenario, encoding being completely offloaded to NVENC makes the graphics engine bandwidth fully available for game rendering.

NVDEC - Hardware-Accelerated Video Decoding
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).
