I encountered errors when running a python program using OpenCV and PyQt5 on Jetson ORIN NX：

But I use MobaXterm connect to ORIN NX, I can run the program successfully.

Hi,
It seems to be a failure in gstreamer frameworks. Please clean the cache and see if it works:

$ rm .cache/gstreamer-1.0/registry.aarch64.bin
4

Hello,
It do not work：
sudo rm /home/nvidia/.cache/gstreamer-1.0/registry.aarch64.bin
I got the same error message.

5

I use MobaXterm - SSH protocol to connect ORIN NX and execute programs in MobaXterm terminal, and the project works fine .

6

Hi,
Please check which sink plugin is used in the sample. And try to use it in gst-launch-1.0 command. It looks like the plugin only works in MobaXterm environment.

Hi,I run yolov5_detect.py in ORIN NX, It can work properly when I set my source : rtsp://192.168.0.131:554.（ In fact, my programis based on yolov5 detect.py . When I click the button to try to execute detect.py and display the image on the UI, it outputs the error I mentioned at the beginning.）

But I run gst-launch-1.0 rtspsrc location=rtsp://192.168.0.131 latency=0 ! rtph264depay ! decodebin ! videoconvert ! autovideosink in terminal,it can not work:

Is this still an issue to support? Any result can be shared?
