How to Enable Nvidia NVENC for OBS in Linux

OBS on Linux supports using the Nvidia NVENC for H.264 encoding. To get this working, one must compile ffmpeg wtih nvenc support. Check it out!

Requirements:

nvidia proprietary driver installed

Step 1:

Download and extract Nvidia nvenc sdk from: https://developer.nvidia.com/nvidia-video-codec-sdk

From that download, copy the file
/Video_Codec_SDK_7.0.1/Samples/nvEncoder/NvEncoder.h
to
/usr/local/include

Step 2:

Download and extract the Nvidia cuda sdk from: https://developer.nvidia.com/cuda-downloads

Copy
cuda.h
to
/usr/local/include

Step 3:

Grab the latest ffmpeg and configure with:

--enable-nonfree --enable-nvenc
Compiling and installing ffmpeg may vary wildly by distro, or you may have your own preferred way to compile and build ffmpeg.

Debian Example

Below are debian specific using the latest nvidia driver from nvidia.com with steps which will result in a .deb file installed and ffmpeg executable at /usr/local/bin/ffmpeg

 sudo apt build-dep ffmpeg  sudo apt install yasm nasm                  build-essential automake autoconf                  libtool pkg-config libcurl4-openssl-dev                  intltool libxml2-dev libgtk2.0-dev                  libnotify-dev libglib2.0-dev libevent-dev                  checkinstall libavcodec-extra57
 git clone git://git.videolan.org/ffmpeg.git
 cd ffmpeg

 make -j4
 sudo checkinstall
