A wrapper playlist can contain references to media files that are streamed before and after the content that is requested by the client. Hence, the media files wrap the requested content. You can use a wrapper playlist to guarantee that every client that is connected to a publishing point renders specific content. In the following wrapper playlist example, media content is inserted before and after the requested content indicated by the "%url%" placeholder:

<seq>
     <media src = "c:\wmpub\wmroot\content1.wmv"
     <media src = "%url%"
     <media src = "c:\wmpub\wmroot\content2.wmv"
</seq>

Example Code

  EXIT:
    // TODO: Release temporary COM objects and uninitialize COM.

Requirements

Header: wmsserver.h.

Library: WMSServerTypeLib.dll.

Platform: Windows Server 2003 family, Windows Server 2008 family.
