     253```
     254   --enable-libnpp          enable Nvidia Performance Primitives-based code [no]
     255   --enable-cuda-nvcc       enable Nvidia CUDA compiler [no]
     256```

     258Both of these are basically "older" versions that require the nvidia SDK to be present when compiled and run.  libnpp provides scale_npp (and a few other filters) whereas ffnvcodec provides scale_cuda ("GPU accelerated video resizer"), and a few other filters.  They might have different options.  Might be similar performance.  These have funky licensing (nonfree).
