Hello,

I have got my jetson nano, and while trying to connect to camera and run python face_detect.py it throws this error

Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:532 Failed to create CaptureSession

Any help is appreciated!

Hi,

Is there any camera connected to the Jetson Nano?

From your log, it looks like the camera cannot be opened.

Failed to create CaptureSession

By the way, could you share the source of face_detect.py with us?
Thanks.

I figured it out the problem. it was related to OS, as the OS got locked the camera (might be I was running gst before) and I could not run another program to use the camera.

#4

Thanks for the feedback.
Is the application good now?

#5

I just run that for checking the live camera, I switched to running Yolov3. Its run successfully, the only concern is that it is very slow I can say with 7s delay or more.
Do you have any suggestion about how to improve it?

#6

Hi,

Could you try if maximizing the device performance helps?

sudo tegrastats

Thanks.

#7

I am seeing this on my lepord imx334 some time, I have to reboot, so is it a driver lock up type probem?

#8

Hi,

Sorry that we need more information to figure our the cause.
Would you mind to share the detail error log with us?

Thanks.

Thanks,

Hi,

Did you see any error log when the creation failed?

Ex.

SCF: Error BadParameter:  (propagating from src/api/CameraDriver.cpp, function getSourceByGuid(), line 453)  ...

Thanks.

dmesg does not show anything, I am using a leporard imaging camera on R32.1
Thanks,

Hi terrysu50z,

Hi Friends,

I have connected my camera module to the NVIDIA Jetson Nano. After that, i run a camera launch command to check whether it is working fine or not.

The camera module is working fine and i run my code then i got the error as mentioned below:

Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:568 Failed to create CaptureSession
