I post on the
support forums for OBS all the time, so if any of you guys have an issue that no one picked up on there, pm me here and I'll take a look.
I really hate that people have to think about that as streaming seems to be a fun thing/good advertising. Would it lose much if you just posted it after FSO was over, like on a 3 hour delay? Keeping the radio box offscreen seems like a good idea too.
The following only applies if you're using OBS to stream, but I'm pretty sure OBS still limits you to a 900 second (15 minute) delay. I asked for a longer delay
years ago but the main developer couldn't comprehend my reasons for wanting it. So assuming that's still the case (I haven't attempted to use a long delay in many versions now), you'd be better off just recording the video to your hard drive and uploading it as a file later (to Twitch, or YouTube).
There was a previous discussion on stream-sniping / scenario streaming here:
http://bbs.hitechcreations.com/smf/index.php/topic,378775.0.html that is a good read. In the past 2 years, things have evolved further and Twitch isn't nearly so niche anymore. I personally think each commander should ban his side from live-streaming the event, and perhaps some neutral admin players could stream it instead in such a way to be sure not to give anything away. Set it up like sports announcers with live-lookins (ala NASCAR), but don't bring up anything tactical or strategic that only one side can see... public info only.
