I would love to see if this could be integrated:
https://developer.nvidia.com/nvidia-codec-libraries (nvcuvenc).  There
"may" be libraries for linux, I haven't looked into it too much, but
every so often people that do live streaming with ffmpeg "wish" they
could use the graphics card for encoding, to save on cpu, so it might
be an interesting fit.
