FFmpeg version of headers required to interface with Nvidias codec APIs.
Corresponds to Video Codec SDK version 8.0.14.
Minimum required driver versions:
Linux: 378.13 or newer
Windows: 378.66 or newer
Right now, if someone configures ffmpeg with for example --enable-nvenc they will
get an error message complaining about missing cuda.
This is very confusing and already has lead people into installing the CUDA SDK,
even though it's not what they need.
This will make it complain about ffnvcodec instead.
