Hi,

I have compiled the gstthetauvc plugin and am attempting to run it on a Jetson Xavier NX, however I receive the error :

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

I have successfully gotten it running on a Jetson Xavier AGX, as well as an Ubuntu desktop PC. Just wondering if there are any obvious steps that I've missed for the NX? Possibly permission issues?

Thanks

I don't have a Jetson Xavier NX. This person had a permission problem with spot core (robot processing board) based on i5 Intel 8th gen. https://community.theta360.guide/t/live-streaming-over-usb-on-ubuntu-and-linux-nvidia-jetson/4359/332?u=craig

The solution was to add permissions to a user called plugdev

sudo usermod -aG plugdev [SPOT_CORE_USER]

I'm not sure if this user is on the OS running on the Jetson Xavier NX.

You can try and post to the forum. I suspect other people are streaming from the Xavier NX. Unfortunately, I don't have one. I'm thinking of getting the Jetson Orin Nano when it comes out.

We managed to find the solution. Turns out it was as simple as setting an environmental variable in bash:

export LD_LIBRARY_PATH=/usr/local/lib

For whatever reason, this is automatically set on Intel based Ubuntu, and the Xavier AGX series board, but not the NX!

Oh wow, this is fascinating. Thanks for sharing this. I'll post this in the forum. Other people had problems with the NX.
