"CAMERA STREAM FAILED TO START" Error

Hello,

I am trying to use the ROS 2 Wrapper for ZED SDK 5.0 on the Clearpath Jackal robot. When I build the zed-ros2-wrapper package (which does so successfully) and run ros2 launch zed_wrapper zed_camera.launch.py camera_model:='zed2', I get the following error:

[WARN] [1748619609.120511821] [zed.zed_node]: Error opening camera: CAMERA STREAM FAILED TO START

FYI, I am running CUDA 12.8, ZED SDK 5.0 (TensorRT 8), Ubuntu 24.04, ROS 2 Jazzy. I have also checked that the ZED camera shows up in lsusb so I don’t think it’s a connection problem.

Could I get some help getting around this issue? Since the Jackal is running a Ubuntu server w/o a desktop GUI installed, I can’t use the ZED Diagnostic Tool to debug this

Hi @apark0115
Welcome to the Stereolabs community.

We need more details about your device’s status and system configuration to gain a clearer insight into the cause of your issue.
Could you connect the camera to the USB3 port, launch the ZED Diagnostic tool, and send the report file it produces?

Hello Myzhar – Thanks for the reply. I was able to get it working by rebooting the camera via /usr/local/zed/tools/ZED_Explorer --reboot. For some reason, the camera shows up as not available when I boot the computer. Thanks.
