Hi Danil,

1) cuda-llvm also suffices and doesn't require non-free.
2) Identify what npp is and make clear that only npp filters require 
libnpp. For either cuda-nvcc and npp, nonfree is also required.

Same note about cuda-llvm.

Note that it is "configure FFmpeg with libnpp" in addition to cuda, and 
with nonfree.

Rest all looks ok.
