Why camera sometimes si giving error end of stream?

I am using this “jetson.utils.videoSource”
image = input.Capture("/dev/video0")
when my application runs for a long time then it is ending up to “End of stream”
What does end of stream mean on envidia?

hello bryllatKS,

may I know which JetPack release you’re working with, and what’s your use-case?
how many hours did you put the camera for running, is there any post-processing executed?
thanks

Hi JerryChang,

$ sudo apt-cache show nvidia-jetpack → gives me:

Use-case is:
We use videoSource to capture 5 images from 5 different /dev/video{com-s} and save them locally using saveImageRGBA. Those 5 pictures are taken very 5 minutes. We let nvidia running throw all the night when we finished work. Next morning the error was shown in terminal :) “End of stream”

hello bryllatKS,

are you working with Xavier NX SD-card or eMMC version?
did you check the storage to confirm you’re still having enough space for saving capture frames?

could you please also narrow down the issue by putting camera to preview streams.
you may enable argus_camera application, and switch to “Multi-session” modes.
or,
you may enable 13_multi_camera, this multi_camera sample captures multiple cameras and composites them to one frame.
thanks
