Structs
AAdditionalInfoEvent
ACameraCaptureFailure Struct to describe a capture failure.
ACameraCaptureSession_captureCallbacks ACaptureCaptureSession_captureCallbacks structure used in ACameraCaptureSession_capture and ACameraCaptureSession_setRepeatingRequest.
ACameraCaptureSession_captureCallbacksV2 This has the same functionality as ACameraCaptureSession_captureCallbacks, with the exception that captureCallback_startV2 callback is used, instead of captureCallback_start, to support retrieving the frame number.
ACameraCaptureSession_logicalCamera_captureCallbacks This has the same functionality as ACameraCaptureSession_captureCallbacks, with the exception that an onLogicalCameraCaptureCompleted callback is used, instead of onCaptureCompleted, to support logical multi-camera.
ACameraCaptureSession_logicalCamera_captureCallbacksV2 This has the same functionality as ACameraCaptureSession_logicalCamera_captureCallbacks, with the exception that an captureCallback_startV2 callback is used, instead of captureCallback_start, to support retrieving frame number.
ACameraCaptureSession_stateCallbacks Capture session state callbacks used in ACameraDevice_createCaptureSession and ACameraDevice_createCaptureSessionWithSessionParameters.
ACameraDevice_StateCallbacks Applications' callbacks for camera device state changes, register with ACameraManager_openCamera.
ACameraIdList Struct to hold list of camera device Ids.
ACameraManager_AvailabilityListener A listener for camera devices becoming available or unavailable to open.
