This file is entirely based on what was already in ffmpeg, or what was
available publicly via google search results.

I'm not sure if I ever opened and looked at cuda.h, but I definitely
avoided doing so when writing this header.

The only thing that was not obvious from already existing code in ffmpeg
was the CUDA_MEMCPY2D struct, which is conveniently documented by just
entering the struct name to Google:
