All of them. And since they are incompatible...

> For example, (as advised by https://developer.nvidia.com/ffmpeg), I would have to configure a build of FFmpeg as follows:
> 
> ./configure --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp 
> --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64

It means that you are not allowed to distribute the resulting binary.

Both NVidia and FFmpeg are responsible for it. I leave you to judge
which one is guilty.
