Hi,
Am trying to work with UVC Camera and Samsung S7 Android Device. Trying to test usbCameraTest app, after I click camera icon on UI, the app completely crashes with below log. I see uvc_scan_streaming is called like,
scan_ret = uvc_scan_streaming(dev, info, block[i]);
However method signature is uvc_error_t uvc_scan_streaming(uvc_device_t dev, uvc_device_info_t info, int interface_idx)
How come block being assigned to interface_idx ?
Need your help on this.
Thanks
