Comment (by oromit):

 I have no idea what you are going at, to build the scale_npp filter, you
 need libraries and headers that are part of the CUDA SDK, not of the set
 of re-implemented headers ffmpeg supplies, which is what the cuda
 dependency in configure ultimately means.
 The cuda_sdk dependency was newly introduced and libnpp updated for them

 I agree that the minimum required driver version should be indicated in
 some place visible from a libavcodec binary. Might just add it to the
 error message when encoder initialization fails, but that might confuse
 people, as there are numerous reasons why that function might fail.
