However, there's still no way to save/export scenes, aside from simply copying your entire app data directory. I just have a basic layout with few tweaks so it's not the worst thing ever, but for any streamer with a complex setup and carefully adjusted filters, moving to a new computer or whatever must be an enormous pain point.
If you keep all of your media and such in the same folder, then the new Missing Files dialog on startup will also auto detect every source after you point one to the new location.
You can share any screen or desktop from the main app and have friends connect
There are, or were, no good turnkey solutions for this. Twitch and Youtube have 5-10s latency, which is often not good enough. Mixer promised (and presumably delivered) ~1s latency using the FTL protocol you use, but they had a wait list of a couple of days or weeks, and of course now, they don't exist anymore. Even Steam Play Together, ostensibly built for this purpose, wasn't low latency enough in my limited experience (this really surprised me, so maybe I'm doing it wrong).
The easiest solution, use the share desktop function of whatever video conference tool, almost works, but they universally seemed reduce the frame rate, which is ok for presentations but unsuitable for games (also, no audio). My solution was to output OBS to a virtual webcam device and use Jitsi Meet. A bit roundabout, but it worked wonderfully.
Ideally, I'd forgo the DO droplet, and just run everything locally. 20% of a small droplet is even less of a modern desktop computer's CPU. Which leaves upload bandwidth for broadcast, which depends on your connection and how many people you need to be able to stream to.
If their current balance is over two years worth of their annual budget and the users are happy with the project and how its progressing, I'm happy to think they're in a good place until I hear evidence to convince me otherwise.
I think a few bounties have been given out as well, but there isn't an entirely formal process for those yet.
OBS can be used as a virtual camera? I assume not out of the box but only with some third party software/plugin, right?
This is not true lol
