The above error is because the camera Acquistion status is TRUE. The camera features cannot be changed and error -12 occurs. So I request you to check the feature AcquisitionStatus and check if the feature is set to True. If it is so then provide an AcquisitionStop until the AcquisitionStatus changes to FALSE.

2 years ago How do I do that? I am facing issue using the with context managers. Is there any way to know that the camera has been closed after leaving the with context manager? Currently I am relaying on time.sleep() to wait after with statement which is not ideal.

2 years ago I changed my code from synchronous to asynchronous as shown below, as above error codes were related to opening and closing of the camera object. This code works fine for 1min after that it just hangs, seems the handler is just stops getting called by the vimba system.

2 years ago Hi, we have exactly the same problem, tested with all 20 USB allied vision, just one connect to a Jetson Xavier NX. Is there any workaround of fix?
Teresa-AlliedVision
commented
1 year ago Hello, we are working on reproducing the issue. For reproduction, please let us know the specific Jetpack version you have on your boards. If this specific issue is the same as a similar one we have seen on some integrated USB cards on PC, then downgrading the firmware to version 7 could help avoid the issue. Please note, that some newer features will not have been implemented on FW7, so it is recommended to check the release notes. https://cdn.alliedvision.com/fileadmin/content/documents/products/software/firmware/Alvium_USB_Firmware_Release_Notes_2022-12-19.pdf Unfortunately no other workaround is known at the moment. Please send an email to support@alliedvision.com with your request for firmware 7, the serial number of your camera and the model (e.g. Alvium U-500c), to receive a download link. Cheers, Teresa

1 year ago @sabariMLIT18 I tested your code (with some simplifications) on a Jetson NX and was unable to provoke any problem. I saved 500+ frames without issue. If you have a reliable reproducer (with only Allied Vision cameras), please upload it here or send it to support@alliedvision.com.

1 year ago I have the same issue, with 2 Alvium cameras connected to a jetson AGX Orin. The code I am using is the code suggested here. https://github.com/alliedvision/VimbaPython/issues/143#issuecomment-1380072389

1 year ago What firmware do the cameras have and what Jetpack version do you use?
With the AGX Orin I personally found the two USB ports on the opposite side of the Ethernet port to work better, next to the pin header.
Hi I have a USB camera from allied vision. I am getting the following error: vimba.error.VimbaCameraError: <VmbError.Timeout: -12>
However after I restart the jetson the code works maybe once or twice before this error comes again. After this only was to make the camera work is restart or manually disconnect USB cable. Below is my code :
What am I doing wrong?
