I've done a little more research. It's kind of hard to get started but I
have found a couple of threads that are useful and IRC had been very
helpful too.



IIUC there is already gpu decoding support. I'm looking into how that
works. Seems documentation is sparse.

There has also been some effort on porting the x264's lookahead thread on
the gpu to ffmpeg. However I think that is going to stay x264 specific?

I would like to ask members of this list if they could help me to compile
a comprehensive non binding roadmap for the priorities for GPU support in
FFMPEG and associated libraries. Obviously it is not going to be a panacea
but there are clearly places where it would be beneficial for people who
had access to  certain hardware and a good reason to utilise it.
