Remarks
You can use data source plug-ins to receive content from an encoder, file system, or a network.
The following system plug-ins can be accessed by using the get_DataSources method.
| Plug-in | Description |
| WMS File Data Source | Enables the Windows Media server to access playlist and media files that are stored on a FAT, FAT32, NTFS, or CIFS file system. |
| WMS HTTP Download Data Source | Enables a Windows Media server to access playlist files from a Web server. |
| WMS Network Data Source | Enables a Windows Media server to pull a distribution stream from an upstream server or encoder. |
| WMS Push Data Source | Enables push distribution of a stream from an encoder to a Windows Media server. |
To create custom data source plug-ins, see Creating Data Source Plug-ins.
This method calls AddRef internally. To avoid memory leaks, you must call Release when you are finished using the interface.

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