Description

The app uses +[AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo] when capturing alert photos. On systems with multiple camera inputs, including virtual devices such as OBS Virtual Camera, the captured image may come from the wrong input. There is no UI or preference to select the intended camera.

Whilst adding some sort of menu item to the UI would probably the most accessible fix, to begin with I think just using a AVCaptureDeviceDiscoverySession to find the first built-in camera rather than allowing macOS to decide what the default is would help.

Research direction

Start at the alert-photo capture entry point that calls +[AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo] and review how AVFoundation camera inputs are selected. Done means the capture path uses an AVCaptureDeviceDiscoverySession to choose the intended built-in camera rather than allowing the system default, including when virtual cameras are present.
