RICOH Live Streaming Driver (THETA UVC Blender) with Equirectangular Output
The USB driver appears as a web cam to applications running a Mac or PC. In the example above, the equirectangular video is shown streaming in QuickTime. A video clip that shows the output of the THETA S USB live streaming is available on YouTube.
You must install the live streaming driver, THETA UVC Blender. Download it from
This walkthrough is for Windows 10 64 bit.
Right click on the UVCBlender_setup64_en.exe icon. Run as administrator
Run through the install wizard.
After installation, you will need to connect a THETA that is powered off to register the device. You may need to reboot. In my tests, I could not advance to the UVC register step without a reboot. If I try and register the device without rebooting, I see a flashing Establishing a Connection dialog, but the connection is never completed.
If you need to reboot, run the THETA UVC Register application as administrator.
After a reboot and starting THETA UVC Register as administrator, I then plug the THETA in. The THETA is turned off. The connection is established.
The registration completes.
At this stage, you may need to reboot again. If you do, it is a one-time requirement.
Now, press power and mode to start the THETA S in live streaming mode. Test it with a common video streaming application such as Google Hangout. I have heard of people having problems displaying the stream. Start your application first with the camera unplugged. Once the application is running, select THETA UVC Blender, then start your THETA in live streaming mode, and plug it in. There are probably other ways to get the application to recognize the live stream, but this sequence consistently works for me.
Go into the settings of Google Hangout to select the THETA UVC Blender webcam.
Here’s an example with Open Broadcaster Software.
Create a new Scene called THETA Test. Right click in Sources to Add a new Video Capture Device
Under the Device Selection window, select THETA UVC Blender. Click OK.
The video stream will fill a portion of the screen. Select Edit Scene to size the video stream to fit.
You can use OBS or other software to stream the image to YouTube. Refer to the blog post below for more information:
