I've been mulling the idea of setting up a more robust dual-PC streaming setup. I've got no shortage of PC's around the house, so it wouldn't require buying a new PC, just the various peripherals. I thinking about it for a few reasons. First, is for fun. I'd like to do the occasional streaming when I play video games, I find when I steam I have more fun because I'm more conscious of what's going on and I like the performative aspect of it, especially my non-toxic, left wing, lets-all-be-good-to-each-other nature. I'd also like to playing around with more explicitly mixing work and play, and adding some AR/VR/games research chat into it.
But I also would like to use this for work. I've done a lot of recording for the AR/VR projects I'm doing at Mozilla and Georgia Tech, and it's often a pain to get the results to look good. Having a really good capture setup, that just so happens to also stream, would be great. I've done a few "stream some WebVR content to twitch as a way of recording it" and it works great; OBS let's you have different scene setups for different purposes, so creating scenes with multiple cameras or greenscreen overlays of video cameras would be super useful.
I was thinking about this again because this video from an Jayne (an Overwatch professional streamer and league coach) came up in my inbox as a suggestion, and it provided some good tech advice that cut through a lot of the conflicting (and often unjustied-but-ferverent) opinions you find if you search for streaming rig setups. Check it out if you're interested, I may just have to buy some of this gear and give it a try.
