ffmpeg give an exception: Cannot load libnvidia-encode.so.1.
Lib libnvidia-encode.so.1 is present in /usr/lib64, with a symlink to
libnvidia-encode.so.381.22 (driver library).
ldconfig show this libary as loaded.
{{{
libnvidia-encode.so.1 (libc6,x86-64) => /lib64/libnvidia-encode.so.1
}}}
And
{{{

}}}
By using drivers from 375.xx branch - all is ok.
