The Video Codec SDK includes a complete set of high-performance tools, samples and documentation for hardware accelerated video encode and decode on Windows and Linux. The SDK consists of two hardware acceleration interfaces: • API for video encode acceleration • 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 engine for video decoding (referred to as NVDEC) supports faster than real-time decoding which makes it suitable to be used for transcoding applications, in addition to video playback applications. * Diagram represents support for the NVIDIA Pascal GPU family ** 4:2:2 is not natively supported on HW *** Support is codec dependent. 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. 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. * Diagram represents support for the NVIDIA Pascal GPU family ** 4:2:2 is not natively supported on HW GPU H.264 (AVCHD) YUV 4:2:0 H.264 (AVCHD) YUV 4:4:4 H.264 (AVCHD) LOSSLESS H.265 (HEVC) YUV 4:2:0 H.265 (HEVC) YUV 4:4:4 H.265 (HEVC) LOSSLESS MAX Color MAX Res.
