Hi,

Thanks for reporting the issue.
I'll look into it right now.

I updated the package, could you try again ?

Best,
Benjamin V

The above error will not occur with the upgraded package, but when I try to run the demo in the Examples folder, unity3d prompts that the camera can be found but cannot be opened, as shown in the following figure

Can you try to open it using ZED Explorer or unplug/plug the camera ?

When I open it with ZED explorer, it gets stuck at ''waiting for camera''
However, using matlab the camera can be opened normally.

Hi,

Could you try to update the ZED SDK to 3.6.5. The latest update of the v4l2 driver for Ubuntu was causing connection problem with our devices using the ZED SDK. This issue has been fixed with the 3.6.5 patch.

Best,
Benjamin Vallon
