IWMSPublishingPoint.WrapperPath (C#)

The WrapperPath property specifies and retrieves the path to a wrapper playlist file.

IWMSPublishingPoint.WrapperPath = string;
string = IWMSPublishingPoint.WrapperPath;

Property Value

A string containing the playlist.

If this property fails, it throws an exception.

Remarks

This method is not supported for cache proxy publishing points.

A wrapper playlist can contain references to media files that are streamed before and after the content requested by the client. Hence, the media files wrap the requested content. You can use a wrapper playlist to guarantee that every client 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

using Microsoft.WindowsMediaServices.Interop;
using System.Runtime.InteropServices;

// Declare variables.
WMSServer              Server;
IWMSPublishingPoints   PubPoints;
IWMSPublishingPoint    PubPoint;

string                 strText;

try {
    // Create a new WMSServer object.
    Server = new WMSServerClass();

    // Retrieve the IWMSPublishingPoints object.
    PubPoints = Server.PublishingPoints;

    // Retrieve information about each publishing point.
    for (int i = 0; i < PubPoints.Count; i++)
    {
        PubPoint = PubPoints[i];

        // Retrieve the path to the wrapper playlist.
        strText = PubPoint.WrapperPath;

        // Set the path to the wrapper playlist.
        strText = "c:\\wmpub\\wmroot\\wrapper.wsx";
        PubPoint.WrapperPath = strText;
    }
}
catch (COMException comExc) {
    // TODO: Handle COM exceptions.
}
catch (Exception e) {
    // TODO: Handle exceptions.
