git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git
cd nv-codec-headers
edit Makefile to use /usr as PREFIX and lib64 as LIBDIR instead /usr/local and lib, after build and install with:
make
sudo make install

libcdio-paranoia-devel \
libmp3lame-devel \
libnut-devel \
libv4l-devel \
libpulseaudio-devel \
libsndio-devel \

after get package from http://distrib-coffee.ipsl.jussieu.fr/pub/linux/Mageia/distrib/7/SRPMS/core/release|updates and edit spec file to add –enable-nvenc after remove sdl in BuildRequires and rebuild
rpmbuild -ba --define 'distro_section tainted' --with plf --with fdkaac ffmpeg.spec

lib64ffmpeg-devel-4.1.4 \
lib64postproc55-4.1.4 \
lib64swresample3-4.1.4 \
lib64swscaler5-4.1.4
after install packages without static-devel, debugsource and debuginfo packages
in Mageia 6 instead you need only to:
# ln -s /usr/lib64/nvidia-current/bin/nvidia-modprobe /usr/bin/nvidia-modprobe
# ln -s /usr/lib64/nvidia-current/bin/nvidia-smi /usr/bin/nvidia-smi
