After reading this article in Japanese, I learned that there was a pre-release software called RICOH THETA UVC 4K that the writer reported helped with live streaming in 4K on Windows 10. The writer contacted Ricoh customer support in Japanese. I tried it and got the software.
Update 10/13/2017: Driver now on Ricoh Site for Immediate Download
Just saw this FAQ.
Update 10/18/2017: Single channel audio now works with Windows 10 Fall Creators Update
See this post down in the discussion. Note that Fall Creators update was released on 10/17. This is Windows 10 version 1709, not the older 1703. Audio from the THETA V does not work with Windows 10 1703, but you can mix it with an external microphone.
Using RICOH THETA UVC 4K With OBS
I’m getting excellent results with RICOH THETA UVC 4K. I’m assuming this will be released more widely after the Ricoh team tests it more. I indicated that I would write up my experiences.
Live streaming video quality is excellent, much better than the THETA S. If you do live-streaming, you need to upgrade! This is a massive improvement. It’s a game-changer as the THETA S could not really provide an immersive experience for live streaming due to fuzzy details. With the new resolution, telepresence should be great.
Using the pre-release software, I found MPC-HC and OBS to both work great. Live streaming quality and smoothness were excellent.
Update: 9/27/2017. I just ran the test again and am now only seeing 10% system load on OBS 19.0.3.
Note that a previous version of this article showed high load on OBS 0.65, which I mistakenly used for my test. This is old software. I’m running the test again for OBS 19.0.3 now. CPU load is now 10%.

Note on Using MPC-HC Without UVC 4K Driver
Don’t select Microphone (RICOH THETA V) as Audio. If you set it, MPC-HC does not show the live stream from the RICOH THETA V as a web cam. It’s an issue with the Windows USB driver. If you set as the screen below, you can see the live from the RICOH THETA V on the MPC-HC without UVC4K.
Update: 11/7/2017 - tested THETA V driver with MPC-HC
To access the settings, go to View -> Options
Under options, select Capture - > Video
On my system, I have a multiple webcams and multiple drivers. Select RICOH THETA V.
