[FFmpeg-devel] [PATCH 0/5] Clean up CUDA SDK usage and remove non-free requirement

[Soft Works]

> I've been thinking about this for a while, but I only recently made the
> realisation that compiling cuda kernels to the ptx format does not
> introduce any non-free dependencies - the ptx files are an intermediate
> assembly code format that is actually compiled to binary form at
> runtime. With that understood, we just need to switch the remaining
> users of the CUDA SDK to ffnvcodec and we will remove the non-free
> entanglements from cuda.

LGTM

We've tested the yadif_cuda and scale_cuda filters after applying all
patches and it's working fine. (Windows builds via MSYS2, CUDA SDK 8.0)
