 Hi,

 I notice you aren't currently providing official builds on Windows with
 `--enable-libnpp`, which notably makes it impossible to use both GPU
 decoding and GPU encoding in the same ffmpeg run, due to needing to
 provide scaling parameters in that case like so: `vf
 "hwupload_cuda,scale_npp=w=1280:h=-2"`, per this ticket:
 https://trac.ffmpeg.org/ticket/5587.

 Is it possible to provide builds with libnpp on Windows currently, or is
 this a CUDA limitation?
