This would only be interesting if it kept the ability to build without
cuda.h being present. Possibly optionally this would be ok, if the
original features would be kept intact. Then it would only avoid a hard
runtime dependency on the cuda libraries.
Keep in mind that in the not too distant future our cuda/nv header will
move out of the main ffmpeg repository to
So I'd say it's better to integrate the patch there, possibly
duplicating the dynlink_cuda header into one version that works without
cuda.h and one that uses it to offer a more complete dynloading.
