Hello @KevorkSulahian I am facing the same issue, did you solve it?

[KevorkSulahian]

Hey @isaac-223 I unfortunately did not, if you do please make sure to write to me I will really appreciate it

[init-22]

@KevorkSulahian so the error was related to camera which didn't have proper setup; I changed the camera and it worked!

[carlinl]

I ran into the same issue and stuck for several days, I would be appreciated if someone can help. It shows the same issue on both CSI and USB camera.

[KevorkSulahian]

Apparently you have to change the camera

[carlinl]

Honestly, I don't think it's because of the camera, cuz both of them got the same error, and I tested USB camera on my MAC, it worked fine, also the type of the camera is compatible with Jetson Nano. Thanks anyway :P
I'll comment out if I have any progress.

[KevorkSulahian]

Hope you're right and if you find a fix for it let me know because I can't use mine

I solve this problem by reinstall the older version of the Jetson Nano image on SD-card. I tested the usb camera by installing camorama and cheese, after running cheese command it worked fine. I guess it might because there's some unsolved issue on latest version of image.

[stephentandjiria]

Hi @carlinl I am also stuck on this problem with Jetpack 4.5.0.
Could you please tell me which older version of Jetpack image you installed?

[carlinl]

I've installed Jetpack 4.4

[stephentandjiria]

@carlinl thankyou, I really appreciate it!

Though for anyone reading this, at this point I still can't confirm Jetpack 4.4 works because my download for both 4.4 and 4.4.1 zip files are corrupted for unknown reasons, but I believe it's worth to try.

[KavitShah1998]

@KevorkSulahian so the error was related to camera which didn't have proper setup; I changed the camera and it worked!

I am facing the same issue with Jetson Nano, Jetpack 4.5.1 & raspi v2 camera.

@init-22 could you explain which camera were you using initially & what did you replace it with? Also what steps did you follow for the "setup" of your new camera?

I will also try out the method suggested by @carlinl, but wanted to see if there is any quick fix for it.

[init-22]

@KavitShah1998 I was using Waveshare IMX219-160 and then I switched to Arducom IMX291. Hope this helps

[ghost]

@init-22 I am using waveshare IMX219-160 and it worked in the past.Now it did not work. I am waiting for my Arducom IMX291.

[AlexandreBourrieau]

You certainely make a shortcut with your camera in the heatsink so now your camera module is broken

[radhen]

ave to change the camera

I have tried three cameras, one from Arducam (B0342) and two from Waveshare (IMX219-160). I get the same error for all three cameras. Did anyone find a solution to this problem? I am using Jetpack 4.6.

@carlinl , which JetPack version work for you?

I have the same issue, and it doesn't seem to be a camera issue : using gst-launch-1.0 nvarguscamerasrc ! nvegltransform ! nveglglessink works, but using the nvvidconv ! videoconvert pipeline doesn't.
This seems to be a configuration issue somewhere.
Furthermore, the nvvidconv ! videoconvert pipeline worked before I used it in opencv, where it only worked once...
Has anyone gotten more insights into this issue since the last post ?

Could you please share your full gsteamer pipelines? Both with nvvidconv ! videoconvert and with gst-launch-1.0 nvarguscamerasrc ! nvegltransform ! nveglglessink.

In the end I got opencv working : I was using a library that listed v4l2 devices that interacted incorrectly with the drivers for nvargus. Updating the library or removing it fixed the issue.

Hi, @Moddingear , I have met the save problem. Could you tell me what library did you update or remove?

[Moddingear]

Hi, @Moddingear , I have met the save problem. Could you tell me what library did you update or remove?

It was this library : https://github.com/doleron/v4l2-list-devices
The 9 June 2022 version works, the earlier ones don't.

Thank you for your reply! I just figured that the problem is that I did not add -D WITH_GSTREAMER when installing opencv.
