Support/experimentation for live streaming

It would be nice to experiment with using this approach to serve to a browser.

The motivation for this would be to include live layer splitting of emulated games used inside the rest of the superLimitBreak (browser based) infrastructure.

Latency would probably be the primary issue here, so investigation into ffmpeg performance tweaks would be useful.

I will investigate this and maybe get a proof of concept together over the coming weeks
