Hi,

Please excuse my limited English skills.
I’m using a zedxm camera with ROS 2 Humble on a jetson AGX Orin. (zed sdk version = v.5.0.0 )
I was trying to Rviz visualization.
I command ros2 launch zed_wrapper zed_camera.launch.py camera_model:=zedxm and in other terminal ros2 launch zed_display_rviz2 display_zed_cam.launch.py camera_model:=zedxm sim_mode:=true.
It worked normally but suddenly stopped with the following error message.

[component_container_isolated-2] [Streaming] Error: Stream Opening returned TIMEOUT (350)
[component_container_isolated-2] [Streaming] Metadata timeout. the size is equal to -1 instead of 21960. Skipping.

Hi @hannah

What simulation server are you using?

Oh sorry, I don’t use sim_mode.
It seems that sim_mode is not the cause of the problem. Even if I set that value to false, the similar error occurs as above.

Additionally, there is no problem at all when running ZED_Explorer.

Can you please run ZED_Diagnostic and send the report file it generates?

ZED_Diagnostic_Results.json (22.5 KB)
Here it is. And thank you for your reply.

I’m sorry, but I noticed your error just now.

This is not allowed because the command
ros2 launch zed_display_rviz2 display_zed_cam.launch.py camera_model:=zedxm
will try to start a new ZED Node that is already running in the other terminal for the ZED X Mini camera.

You can directly start the node and the viewer with
ros2 launch zed_display_rviz2 display_zed_cam.launch.py camera_model:=zedxm

Otherwise, you can start the node in one terminal with
ros2 launch zed_wrapper zed_camera.launch.py camera_model:=zedxm
and the rviz2 viewer in another terminal with
ros2 launch zed_display_rviz2 display_zed_cam.launch.py camera_model:=zedxm start_zed_node:=false

I didn’t know this. I thought I had to start the node first and then run RViz. Thank you so much.
