MediaElement.LicenseAcquirer Property

Silverlight

Gets or sets the LicenseAcquirer associated with the MediaElement. The LicenseAcquirer handles acquiring licenses for DRM encrypted content.

Namespace: System.Windows.Controls
Assembly: System.Windows (in System.Windows.dll)

Syntax

public LicenseAcquirer LicenseAcquirer { get; set; }

Property Value

Type: System.Windows.Media.LicenseAcquirer
The LicenseAcquirer associated with the MediaElement. The default is null.

Exceptions

Exception	Condition
ArgumentNullException	The LicenseAcquirer is null.

Remarks

The main scenario for using this property is if you are serving DRM-protected content and wish to override the LicenseAcquirer to provide custom license acquiring behaviors such as adding business data or authentication tokens to the license request. See Digital Rights Management (DRM) for more information.

A LicenseAcquirer can only be associated with one MediaElement at any given time. Attempting to set a LicenseAcquirer already associated with one MediaElement on another MediaElement will throw an error.
