Hello,
First i have installed ‘cv2’ package, next i have cloned python code to run ‘Arducam’ or ‘CSI’ camera from here
https://github.com/JetsonHacksNano/CSI-Camera
Next i have tured off Jeston, connect camera, turn jetson on and run this command as it says in ‘readme.md’
“gst-launch-1.0 nvarguscamerasrc ! ‘video/x-raw(memory:NVMM),width=3820, height=2464, framerate=21/1, format=NV12’ ! nvvidconv flip-method=0 ! ‘video/x-raw,width=960, height=616’ ! nvvidconv ! nvegltransform ! nveglglessink -e”
the output this
"
Setting pipeline to PAUSED …

Pipeline is live and does not need PREROLL …

"
Also there are some python files like “simple_camera.py” or "face_detect.py "
When I run
" python simple_camera.py "
the output is
"
nvarguscamerasrc ! video/x-raw(memory:NVMM), width=(int)2592, height=(int)1944, format=(string)NV12, framerate=(fraction)30/1 ! nvvidconv flip-method=0 ! video/x-raw, width=(int)1280, height=(int)720, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink
Unable to open camera
"
Also I have checked cameras with raspberry pi and they work well.
I think problem is with piplines, please help.
