[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Provides common properties for AudioCaptureDevice and VideoCaptureDevice.
System.Windows::DependencyObject
System.Windows.Media::CaptureDevice
System.Windows.Media::AudioCaptureDevice
System.Windows.Media::VideoCaptureDevice
Assembly: System.Windows (in System.Windows.dll)
The CaptureDevice type exposes the following members.
| Name | Description | |
|---|---|---|
 | Dispatcher | Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.) |
| FriendlyName | Gets the UI display name for the capture device. |
| IsDefaultDevice | Gets a value that declares whether the capture device is the default device for its type (audio or video). |
| Name | Description | |
|---|---|---|
 | CheckAccess | Determines whether the calling thread has access to this object. (Inherited from DependencyObject.) |
| ClearValue | Clears the local value of a dependency property. (Inherited from DependencyObject.) |
| Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetAnimationBaseValue | Returns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetValue | Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReadLocalValue | Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.) |
| SetValue | Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
  | FriendlyNameProperty | Identifies the FriendlyName dependency property. |
| IsDefaultDeviceProperty | Identifies the IsDefaultDevice dependency property. |
The properties of CaptureDevice are mainly used to determine how that device is represented in the Windows Phone configuration dialog box on the Webcam / Mic tab. Other properties that are more specific to working with captured data as part of a sink implementation are instead declared on either AudioCaptureDevice or VideoCaptureDevice.
Example scenarios for using CaptureDevice properties include prompting users to change either audio or video devices in their configuration UI. You might prompt the user to change settings if there are alternatives reported by GetAvailableAudioCaptureDevices or GetAvailableVideoCaptureDevices that would work, for cases where the current default device (GetDefaultAudioCaptureDevice, GetDefaultVideoCaptureDevice) is not supported. You can also display strings in the UI, for example, a button with localizable text "Capture video from * device" where * is the FriendlyName.
