What platform? If on Windows or Mac, you can select the preferred camera from the drop-down on the ARXVideoConfig component.

Thank you for your reply. I am developing on the Windows platform and the software is running on the Android platform. The UVC camera is also being used on the Android platform. I tried all the options on the ARXVideoConfig component.The issue is that the software displays that there is no camera connected when running.There is only one camera in the hardware. image

This document https://source.android.com/docs/core/camera/external-usb-cameras indicates that UVC cameras should be accessible to the camera2 API (and therefore supported by the NDK camera API) provided that the Android build has had the flags enabled for external camera access. Can you give any more details about the version of Android in use and/or the hardware platform?
