Marathon64
Continuous livestream using FFmpeg and a Raspberry Pi
I created a Twitch stream of a Nintendo 64 that could run continuously without user intervention, and let me connect to it remotely to configure the stream. I was able to do this after many weeks of painful capture card/driver configuration and scripting, but in the end I was able to work around all the problems and bodge together a setup. It was so hacky that I eventually had C scripts messaging shell scripts to automatically restart reverse SSH tunnels. I'll try running this again someday, hopefully with a much better setup.
