These are the steps to build a ffmpeg deb package with NVENC support to make hardware acceleration available for OBS Required an nVIDIA card with a reasonably updated driver
Install nv encoder headers matching your driver:
Uninstall existing ffmpeg if applicable
Get the ffmpeg source
add "--enable-nonfree --enable-nvenc" to the debian/rules file in the source directory with your favorite editor
Run debuild to run the package, takes a bit of time, grab a glass of water
Install the generated packages that are in .. relative to where you ran debuild
Note, the packages labeled "extra" might not install, you can just omit those
Now NVENC should be available in OBS, and of course to ffmpeg. Try encoding a video with -c:v nvenc_h264 see if it works.
Install nv encoder headers matching your driver:
git clone --branch <version branch> https://github.com/FFmpeg/nv-codec-headers
cd nv-codec-headers
sudo make installUninstall existing ffmpeg if applicable
