FFmpeg supports NVENC through the h264nvenc and hevcnvenc encoders. NVENC NVENC can be used for H.264 and HEVC encoding. nvenc is in fact enabled in ffmpeg-full on Linux amd64: NixOS/nixpkgs/blob/872fceeed60ae6b7766cc0a4cd5bf5901b9098ec/pkgs/development/libraries/ffmpeg-full/default.nix#L109 FFmpeg refers to NVENC/NVDEC interconnect as CUDA.
