CSI camera not working on JetBot/Jetson docker

Robotics & Edge Computing Jetson & Embedded Systems Jetson Nano

I have been trying to make my CSI camera work on my Jetbot for some days. I read many old posts with different people having a similar problem. I have tried their solutions but without any success. I tried to restart nvargus_daemon (sudo systemctl restart nvargus-daemon), download additional jetpack packages, and reinstall the Jetson Nano Developer. When I tried

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 -ereboot

the camera works, but when I try to create a Camera instance, I keep receiving the same error message: RuntimeError: Could not initialize camera. Please see error trace. I think maybe the problem is on docker (jetbot/docker at master · NVIDIA-AI-IOT/jetbot · GitHub). My jet version is 0.4.3 and my LTS 32.5.0. If anyone has something to share that could help me to fix this issue, I would appreciate that.

Thank you.

Unfortunately, I am still getting the same error, and now when I try to run 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, it doesn’t work anymore.

Try the command again after restart nvargus-daemon by below command.

sudo service nvargus-daemon restart

It didn’t work, but your previous answer gave me the idea of trying the jetpak 4.5 instead of 4.6. Problem solved.

Thank you.
