This post by community member dakami on the official forum touches on some possible issues with live streaming. Most importantly, dakami seems to feel that the THETA UVC 1.50 ( the USB Video) support is pretty basic. I suspect this is one reason we may be having some issues with certain applications.

Right now, the UVC 1.50 support is pretty raw. Forget controlling capture parameters, it only barely gets any sort of stream out at all.
There's some twisty path wherein they sort of have in working in Windows, it seems, but it's not like it just shows up as another codec and resolution pair. I'm diving into the driver trying to fix it (I managed to get the PS3 camera working much nicer). I randomly found out recently that Wireshark has super nice USB sniffing now on Windows, so if I can get it up there (and thus far, I haven't really) I can force whatever parameters are needed.
Ah, it's never easy. At least 720p15 works without too much drama.
