I’m trying to get the nvarguscamerasrc pipeline to run in openCV inside an anaconda (miniforge3) environment on the Jetson Nano 2GB.
I’ve succesfully used the script by mdegans your script to install opencv in the miniforge environment and face an issue when trying to access the camera. I think I’m very close, but there is one last error when executing the following line:
mypipeline = "nvarguscamerasrc sensor-id=0 !video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, framerate=(fraction)30/1 ! nvvidconv flip-method=0 ! video/x-raw, width=(int)960, height=(int)540, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink"
cv2.VideoCapture(mypipeline, cv2.CAP_GSTREAMER)
It gives the following error:
[ WARN:0] global /home/uc2/Downloads/opencv-4.5.2/modules/videoio/src/cap_gstreamer.cpp (854) open OpenCV | GStreamer warning: Error opening bin: no element "nvarguscamerasrc"
[ WARN:0] global /home/uc2/Downloads/opencv-4.5.2/modules/videoio/src/cap_gstreamer.cpp (597) isPipelinePlaying OpenCV | GStreamer warning: GStreamer: pipeline have not been created
Error: Unable to open camera
gstreamer should be installed properly and the shared library created with tis script is linked properly (at least it installed)… Did I miss anything? In the non pyhton environment (i.e. vanilla/preinstalled python3.6) python it works just fine:

Any ideas? Is there a missing gstreamer plugin I need to install in python?
