The article below is for the THETA S. I’ll likely update it for the THETA V when the WiFi live streaming feature comes out, depending on what the plug-in looks like. There’s going to be a lot of new features and changes coming to the THETA V after the plug-in store is launched.
I haven’t updated the article below since Feb 2017. It likely needs to be updated. The AVENIRMicro featured in the article is too expensive for small projects. There is a big difference between the THETA S streaming on the THETA V streaming. I recommend saving your money on HDMI fixes for the THETA S right now and wait to see if the THETA V can meet your streaming requirements in the future. The THETA V looks much better for 360 streaming.
In the meantime, I think you’ll get the best experience with the THETA S using the USB live streaming at 2K.
You can see the HDMI sample stream with Streambox in the 2nd video below

It’s an expensive solution and probably not what you’re looking for. Though, I don’t know the specifics of your project.
