My system is Gentoo Linux with the Gentoo nvidia-drivers-396.24.

The Gentoo nvidia-drivers include the following files:

/usr/lib64/libcuda.so -> libcuda.so.396.24
/usr/lib64/libcuda.so.1 -> libcuda.so.396.24
/usr/lib64/libcuda.so.396.24

The Gentoo ffmpeg is compiled with --enable-nvenc:

ffmpeg -buildconf
