The best they offer is DEM ( Desktop Encode Mode). Add frame-buffer based capture (utilizing NVFIR and NVFBC in tandem) for low-latency in-game video capture and broadcast on the fly via ShadowPlay in both HEVC and H.264, and no other competitor comes even close. That's a considerable jump in feature level support that puts it way ahead of other competing solutions. It is functionally similar to competitor implementations such as Intel's QuickSync (usable on Windows via vendor-issued Media Foundation Transforms (MFTs) and on Linux via VAAPI) and AMD's VCE Encoder (accessible on Windows via the AMD AMF-based encoders and on Linux via OpenMAX IL and VAAPI-based implementations, as illustrated here).Ĭompared to both AMD's VCE (on current and previous generation AMD GCN+ class hardware) and to Intel's QuickSync, the current version of NVENC on Pascal is considerably superior, adding much coveted features such as Sample Adaptive Offset filtering for HEVC encodes, an industry-first feature on a hardware accelerator which helps greatly with motion-intensive scenery encodes, and lossless, predictive H.264 and HEVC encoding (4:4:4 pixel format) in the same package across all Pascal offerings. Nvidia's NVENC encoder is a Silicon Intellectual property (SIP) core block designed for flexible and programmable media encodes with fixed-function encoding elements tuned for low-latency, high performance and multi-platform awareness, accessible via both CUDA (Windows and Linux) and DirectX device contexts (Windows only, and on Wine with Linux).
