Hello , I recently had no space left and uninstalled docker image from dusty nv ( jetson-inference ) when I run my code I have this error .

Is it related to the doker because when I reinstall its not working . Please i need a solution !
working with jetson nano

Hello @ali-anass.amradouch,

Allow me to ask a few questions to make sure we are on the same page.

  1. Are you trying to capture outside Docker?
  2. Have you tried capturing with GStreamer gst-launch-1.0 nvarguscamerasrc ! videoconvert ! fakesink ?
  3. Do you have video devices available ? ls /dev/video*

regards,
Andrew

Hi,
Please try Andrew’s suggestion to ensure the camera works in gst-launch-1.0 command. And if you use Jetson Nano with emmc and the rootfs is in emmc, the available space may be insufficient for running a docker.

Thank Andrew for providing suggestion.

Thanks for the anwer .

I’m new to this so I will explain , in fact it was working , one day there was no space left in the device so it cant boot , I removed the jetson-inference dokcer image ( with docker rmi id …) , when It worked and I tested my code , it said failed to create capturesession(). I tried to re connect the camera and now its saying no cameras available . So this gst-launch-1.0 nvarguscamerasrc ! videoconvert ! fakesink is not working , ls /dev/video* says no such file or directory althought the camera is connected .

Please tell me the steps i can follow , ( when you say docker container are you talking about dusty nv jetson-inference repo no ? )

Hi,
It seems like the rootfs is corrupted due to insufficient freespace. We would suggest re-flash the system and see if the camera function is revived.
