First, congratulations on getting it working!

Thank you for sharing the solution.

I’m sorry that I didn’t recommend this earlier. This is a known problem and I was just researching the issue last week when you asked the question. However, I didn’t make the connection between the previous libuvc and your environment. I’m sharing the additional information below to help other people with this problem. Thanks again for contributing your solution.

I am trying to get `gstthetauvcsrc` working on a NVIDIA Jetson Nano. The code co…mpiles without any problems. To test if the GStreamer element works I just try: ``` gst-launch-1.0 thetauvcsrc mode=4K ! queue ! h264parse ! nvv4l2decoder ! nvvidconv ! queue ! fakevideosink ``` This returns the error: ``` Setting pipeline to PAUSED ... ERROR: Pipeline doesn't want to pause. ERROR: from element /GstPipeline:pipeline0/GstThetauvcsrc:thetauvcsrc0: Found 1 Theta(s), but none available. Additional debug info: gstthetauvcsrc.c(495): gst_thetauvcsrc_start (): /GstPipeline:pipeline0/GstThetauvcsrc:thetauvcsrc0 Setting pipeline to NULL ... Freeing pipeline ... ``` The reason that I think that this is caused by the code in the `gstthetauvcsrc` element is that this code https://github.com/ricohapi/libuvc-theta-sample works fine. My question is: does someone know what is causing this problem?

There is a note from the author of gstthetauvc

this was the original problem.
