WM/WMRVExpirationDate

  • Article

Specifies the date when the license expires for a DVR-MS file. After this date, the file cannot be played.

Data Type

The data type is a DATE type stored as a QWORD (STREAMBUFFER_TYPE_QWORD)

Remarks

Windows Media Center sets this attribute if the file contains protected content with an expiration date. If the content never expires or is not protected, Windows Media Center either omits the attribute or sets it to the maximum DATE value, which is 23:59:59.9999999, December 31, 9999.

The DATE type is documented in the Microsoft Foundation Class (MFC) Library documentation. You can use the COleDateTime class in MFC to manipulate this type.
