IWMSServer::get_PlaylistParsers

The get_PlaylistParsers method retrieves an IWMSPlugins interface containing a collection of playlist parser plug-ins. You can use a playlist parser plug-in to support a playlist format.

Syntax

  HRESULT get_PlaylistParsers(
  IWMSPlugins**  pVal
);

Parameters

pVal

[out] Pointer to a pointer to an IWMSPlugins interface containing a collection of playlist parser plug-ins.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Return code Number Description
E_POINTER 0x80004003 Indicates that pVal is a NULL pointer argument.

Remarks

This method calls AddRef internally. To avoid memory leaks, you must call Release when you are finished using the interface.

The following system plug-ins can be accessed using the get_PlaylistParsers method.

Plug-in Description
WMS Directory Playlist Parser Enables you to configure a publishing point to stream Windows Media files from a directory by setting the publishing point path to reference the directory. For a broadcast publishing point, a player will automatically receive all of the files. For an on-demand publishing point, a player can request either a single file or all of the files in the directory.
WMS SMIL Playlist Parser Provides support for playlist files with a .wsx extension that contain Synchronized Multimedia Integration Language (SMIL) 2.0 syntax. By enabling this plug-in, you can deliver a single stream that consists of content from multiple sources; you can also dynamically change the content structure as it streams.

To create custom playlist parser plug-ins, see Creating Playlist Parser Plug-ins.

Example Code

#include <windows.h>
#include "wmsserver.h"

// Declare variables and interfaces.
IWMSServer      *pServer;
IWMSPlugins     *pPlugins;

HRESULT         hr;

// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_WMSServer,
                      NULL,
                      CLSCTX_ALL,
                      IID_IWMSServer,
                      (void **)&pServer);
if (FAILED(hr)) goto EXIT;

// Retrieve a pointer to an IWMSPlugins interface
// containing playlist parser plug-ins.
hr = pServer->get_PlaylistParsers(&pPlugins);
if (FAILED(hr)) goto EXIT;

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