Using USB live streaming, the output looks like this using the THETA V driver, which is the one from the camera. Note that I also have RICOH THETA V 4K installed.
As far as I know, there is no way to get dual-fisheye.
The live streaming does not work with Linux due to the requirement for UVC 1.5 support, which the Linux kernel does not support.
It will only stream to Windows 10 and Mac.
What OS are you using to process the stream? If it’s Windows 10 or a newer Mac OS, you should be fine.
If you’re building something with Linux or Raspberry Pi, it will not work.
Note that I don’t work with Ricoh. I’m just a guy with a THETA V. This independent site does receive funding support from Ricoh, but it is a peer-to-peer site, not an official response from Ricoh.
