AVCaptureDeviceMBS.isAdjustingExposure as boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 13.2 ✅ Yes ❌ No ❌ No ✅ Yes All
The transport type of the receiver. (read-only)
Example 
Var device as AVCaptureDeviceMBS
device = AVCaptureDeviceMBS.defaultDeviceWithMediaType(AVFoundationMBS.AVMediaTypeVideo)
MsgBox str(device.isAdjustingExposure)

The value of this property represents the transport type of the device (USB, PCI, etc). Transport types are defined in <IOKit/audio/IOAudioTypes.h> as kIOAudioDeviceTransportType*.

Some examples using this property:

AVCaptureDeviceMBS.isAdjustingFocus as boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 13.2 ✅ Yes ❌ No ❌ No ✅ Yes All
Indicates whether the device is currently adjusting its focus setting. (read-only)
Example 
Var device as AVCaptureDeviceMBS
device = AVCaptureDeviceMBS.defaultDeviceWithMediaType(AVFoundationMBS.AVMediaTypeVideo)
MsgBox str(device.isAdjustingFocus)

You can observe changes to the value of this property using key-value observing.

AVCaptureDeviceMBS.isAdjustingWhiteBalance as boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 13.2 ✅ Yes ❌ No ❌ No ✅ Yes All
Indicates whether the devise is currently adjusting the white balance. (read-only)
Example 
Var device as AVCaptureDeviceMBS
device = AVCaptureDeviceMBS.defaultDeviceWithMediaType(AVFoundationMBS.AVMediaTypeVideo)
MsgBox str(device.isAdjustingWhiteBalance)

Some examples using this property:

AVCaptureDeviceMBS.isCenterStageActive as Boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 25.1 ✅ Yes ❌ No ❌ No ✅ Yes All
Indicates whether Center Stage is currently active on a particular AVCaptureDevice.

This readonly property returns true when Center Stage is currently active on the receiver. When active, the camera automatically adjusts to keep people optimally framed within the field of view. The field of view may pan, tighten or widen as needed. Certain restrictions come into play when Center Stage is active:

  • The device's minAvailableVideoZoomFactor and maxAvailableVideoZoomFactor become restricted (see AVCaptureDeviceFormat's videoMinZoomFactorForCenterStage and videoMaxZoomFactorForCenterStage).
  • The device's activeVideoMinFrameDuration and activeVideoMaxFrameDuration are limited (see AVCaptureDeviceFormat's videoFrameRateRangeForCenterStage).

Center Stage may be enabled via user control or application control, depending on the current +AVCaptureDevice.centerStageControlMode. When +AVCaptureDevice.centerStageEnabled is true, a particular AVCaptureDevice instance may return true for this property, depending whether it supports the feature in its current configuration. Some device features are mutually exclusive to Center Stage:

  • If depth data delivery is enabled on any output, such as AVCaptureDepthDataOutput, or AVCapturePhotoOutput.depthDataDeliveryEnabled, Center Stage is deactivated.
  • If geometricDistortionCorrectionSupported is true, geometricDistortionCorrectionEnabled must also be true, or Center Stage is deactivated.

AVCaptureDeviceMBS.isCenterStageRectOfInterestSupported as Boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 25.1 ✅ Yes ❌ No ❌ No ✅ Yes All
Indicates whether the device supports the Center Stage Rect of Interest feature.

This property returns true if the device supports Center Stage Rect of Interest.
(Read only property)

AVCaptureDeviceMBS.isConnected as boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 13.2 ✅ Yes ❌ No ❌ No ✅ Yes All
Indicates whether the device is currently connected. (read-only)
Example 
Var device as AVCaptureDeviceMBS
device = AVCaptureDeviceMBS.defaultDeviceWithMediaType(AVFoundationMBS.AVMediaTypeVideo)
MsgBox str(device.isConnected)

The value of this property indicates whether the device represented by the receiver is connected and available for use as a capture device. When the value of this property becomes false for a given instance, however, it will not become true again. If the same physical device again becomes available to the system, it will be represented using a new instance of AVCaptureDevice.

You can observe the value of this property using key-value observing to be notified when a device is no longer available.
(Read only property)

AVCaptureDeviceMBS.isExposurePointOfInterestSupported as boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 13.2 ✅ Yes ❌ No ❌ No ✅ Yes All
Indicates whether the device supports a point of interest for exposure. (read-only)
Example 
Var device as AVCaptureDeviceMBS
device = AVCaptureDeviceMBS.defaultDeviceWithMediaType(AVFoundationMBS.AVMediaTypeVideo)
MsgBox str(device.isExposurePointOfInterestSupported)

You can observe changes to the value of this property using key-value observing.
(Read only property)

Some examples using this property:

AVCaptureDeviceMBS.isFocusPointOfInterestSupported as boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 13.2 ✅ Yes ❌ No ❌ No ✅ Yes All
Indicates whether the device supports a point of interest for focus. (read-only)
Example 
Var device as AVCaptureDeviceMBS
device = AVCaptureDeviceMBS.defaultDeviceWithMediaType(AVFoundationMBS.AVMediaTypeVideo)
MsgBox str(device.isFocusPointOfInterestSupported)

You can observe changes to the value of this property using key-value observing.

Some examples using this property:

AVCaptureDeviceMBS.isInUseByAnotherApplication as boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 13.2 ✅ Yes ❌ No ❌ No ❌ No Desktop, Console & Web
Indicates whether the device is in use by another application. (read-only)
Example 
Var device as AVCaptureDeviceMBS
device = AVCaptureDeviceMBS.defaultDeviceWithMediaType(AVFoundationMBS.AVMediaTypeVideo)
MsgBox str(device.isInUseByAnotherApplication)

You can observe changes to the value of this property using key-value observing.
(Read only property)

Some examples using this property:

AVCaptureDeviceMBS.isRampingVideoZoom as Boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 22.2 ❌ No ❌ No ❌ No ✅ Yes iOS only
A Boolean value that indicates whether a zoom transition is in progress.

(Read only property)

AVCaptureDeviceMBS.isSuspended as boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 13.2 ✅ Yes ❌ No ❌ No ✅ Yes All
Indicates whether the device is suspended. (read-only)
Example 
Var device as AVCaptureDeviceMBS
device = AVCaptureDeviceMBS.defaultDeviceWithMediaType(AVFoundationMBS.AVMediaTypeVideo)
MsgBox str(device.isSuspended)

Some devices disallow data capture due to a feature on the device.

For example, isSuspended returns true for an external iSight camera when its privacy iris is closed, or for the internal iSight camera on a notebook when the notebook's display is closed.

You can observe changes to the value of this property using key-value observing.

AVCaptureDeviceMBS.isVirtualDevice as Boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
property AVFoundation MBS AVFoundation Plugin 25.1 ❌ No ❌ No ❌ No ✅ Yes All
A property indicating whether the receiver is a virtual device consisting of constituent physical devices.

Two examples of virtual devices are:

The Dual Camera, which supports seamlessly switching between a wide and telephoto camera while zooming and generating depth data from the disparities between the different points of view of the physical cameras.

The TrueDepth Camera, which generates depth data from disparities between a YUV camera and an Infrared camera pointed in the same direction.
