Playlist Interfaces

A server-side playlist is an ordered list that identifies the media elements that a server must send to a client. You can use the XML Document Object Model (DOM) and the server object model to manage a playlist dynamically. For example, you can programmatically insert media elements into or delete media elements from an active playlist, randomize playlist elements, create a playlist, load and save existing playlists, and so on. The following table identifies the relevant interfaces. Links to reference pages for these interfaces, listed by programming language, are provided in the See Also lists that follow the table.

Interface	Description
IWMSActiveMedia	Contains information about the active media element in a playlist.
IWMSActiveStream	Contains information about specific audio and video streams in the active media element of a playlist.
IWMSActiveStreams	Contains a collection of IWMSActiveStream interfaces.
IWMSFileDescription	Contains information about a directory, media file, or playlist file in a publishing point path.
IWMSFileDescriptions	Contains a collection of IWMSFileDescription interfaces.
IWMSPlaylist	Contains methods to manage a playlist.
IXMLDOMAttribute	Represents an attribute associated with a media element identified by the IXMLDOMElement interface.
IXMLDOMDocument	Represents a playlist.
IXMLDOMElement	Represents a media element in a playlist.
IXMLDOMImplementation	Contains a method used to determine whether a playlist supports a specified feature.
IXMLDOMNamedNodeMap	Enables you to iterate through a collection of playlist attributes.
IXMLDOMNode	Contains methods that represent the core functionality of all nodes in a playlist.
IXMLDOMNodeList	Contains methods that enable you to iterate through a collection of nodes in the playlist.
