Windows Media Player 11 SDK IWMPTranscodePolicy Interface
The IWMPTranscodePolicy interface provides a method implemented by DirectShow source filters to manage changing the format of digital media files.
In addition to the methods inherited from IUnknown, the IWMPTranscodePolicy interface exposes the following method.
|allowTranscode||Retrieves a value specifying whether Windows Media Player is permitted to change the format of the digital media content to Windows Media Format.|
To retrieve a pointer to the IWMPTranscodePolicy interface, Windows Media Player calls the QueryInterface method of the DirectShow source filter.
