How to build NVEnc

Windows

0. Requirements

To build NVEnc, components below are required.

  • Visual Studio 2019
  • CUDA 10.1 or later (x64)
  • CUDA 11.0 or later (x86)
  • Avisynth SDK
  • VapourSynth SDK

1. Install build tools.

Install Avisynth+ and VapourSynth, with the SDKs.

Then, "avisynth_c.h" of the Avisynth+ SDK and "VapourSynth.h" of the VapourSynth SDK should be added to the include path of Visual Studio.

These include path can be passed by environment variables "AVISYNTH_SDK" and "VAPOURSYNTH_SDK".

With default installation, environment variables could be set as below.

setx AVISYNTH_SDK "C:\Program Files (x86)\AviSynth+\FilterSDK"
setx VAPOURSYNTH_SDK "C:\Program Files (x86)\VapourSynth\sdk"

2. Download source code

git clone https://github.com/rigaya/NVEnc --recursive
cd NVEnc
curl -s -o ffmpeg_lgpl.7z -L https://github.com/rigaya/ffmpeg_dlls_for_hwenc/releases/download/20240902/ffmpeg_dlls_for_hwenc_20240902.7z
7z x -offmpeg_lgpl -y ffmpeg_lgpl.7z

3. Build NVEncC.exe / NVEnc.auo

Finally, open NVEnc.sln, and start build of NVEnc by Visual Studio.

For Debug build For Release build
NVEncC(64).exe DebugStatic RelStatic
NVEnc.auo (win32 only) Debug Release
cufilters.auf (win32 only) DebugFilters RelFilters

Linux (Ubuntu 20.04 - 24.04)
