1) Yes, you need to install the nVidia Linux driver.
2) Yes, you need too to install the CUDA SDK (I recommend a the recent version).
3) And Yes, you need to compile ffmpeg from scratch.

After you installed all, it's quite simple to compile from scratch:
- "export PATH=$PATH:/usr/local/cuda-8.0/bin" (or your newer version).
- "./configure --enable-cuda --enable-cuda-sdk --enable-nonfree --enable-cuvid --enable-nvenc --extra-cflags=-I/usr/local/cuda/include/ --extra-ldflags=-L/usr/local/cuda/lib64/ .." (add here your specific flags).
- "make"
