There's additional discussion on the forum below which might help.

https://community.theta360.guide/t/live-streaming-over-usb-on-ubuntu-and-linux-nvidia-jetson/4359/342?u=craig

The most common problems that I've seen on the forum are:

• camera is mounted as a storage device and needs to be unmounted
• old version of libuvc is installed and needs to be uninstalled so camera can use modified libuvc
• THETA is the only video device and person specified /dev/video1 instead of /dev/video0

Thanks!
I solved this problem.
The camera model I use is THETA X; The system is Ubuntu 20.04 on NUC;

I found that this is a hardware problem: The camera needs to be on the bright screen and in LIVE mode.

But I encountered a new problem.

/GstPipeline:pipeline0/GstThetauvcsrc:thetauvcsrc0：Found 1 Theta(s), but none available.

I tried sudo usermod -aG plugdev [SPOT_CORE_USER] and export LD_LIBRARY_PATH=/usr/local/lib but there is no change;

Thanks for your reply！

do you have another version of libuvc installed?

dpkg -l |grep libuvc

Does it show you have libuvc already on your system?
