Image Tracking Crash on Vuzix M400

Hello,


The sample app crashes on Vuzix M400 glasses when I try to use image and object tracking features before starting the camera. This occurs both with Native Android and Javascript SDKs. There is no problem in instant tracking, face detection and many other features on the same device. All features work perfectly on my smartphone. The error messages are:

Thanks.

Hi,


To get a better understanding of the issue, are you trying with our sample app? Could it be that the StartupConfiguration values are different in the instant tracking samples than in the image/object tracking samples? The error message points to the camera, so I would try a different configuration to see if one of them is working.


FYI: We supported Vuzix M300 until our SDK 8.10. Since then we discontinued to provide support for the Vuzix glasses and never included the M400 version, so I would expect some of the feature not working fine. Sorry for the inconvinience.


Best regards,

Aitor.
