Class VisionOSARKitCameraDevice

Namespace
easyar

VisionOSARKitCameraDevice implements a camera device based on VisionOS ARKit, outputting InputFrame (which includes images, camera parameters, timestamps, 6DOF position information, and tracking status). After creation, you can call start/stop to begin and stop collecting video stream data. When the device is no longer needed, you can call close to shut it down. After close, it should not be used anymore. VisionOSARKitCameraDevice outputs InputFrame through inputFrameSource, and inputFrameSource should be connected to InputFrameSink for use. bufferCapacity represents the buffer capacity of InputFrame. If more than this number of InputFrame are output from this device and not released, the device will no longer output new InputFrame until the previous ones are released. This may cause issues such as frame freezing.
