Use FFmpeg gpu acceleration with Bumblebee

[ndrean]

I posted a question on the Elixlirforum: how to compile FFmpeg on Linux or OSX to use GPU? I target both local dev mode (if on Mac) and prod mode for Fly (Debian based image shipping FFmpeg). Let's see.

I thank Jonathan for his clear response:

It would be nice to have a package with NIF bindings to ffmpeg and precompiled binaries, so that we don’t rely on the global installation, if that’s what you mean. I don’t think that exists currently, and it’s not a priority : )

Yeah, figured as such. There are loads of dependencies that follow the same pattern of relying on global installation of ffmpeg out there. Which makes sense, having to manually upload ffmpeg binaries shouldn't concern the package owner.

FFMpeg has a huge API in terms of flags, for audoi, video, codecs etc.
Transforming this into a (NIFed) usable Elixir function seems like a huge task.
