DSP Plug-in Wizard

  • Article

[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The Windows Media Player SDK provides a plug-in wizard that you can add to Visual Studio. The wizard can generate sample code for a variety of plug-ins, including the following types of DSP plug-ins:

  • Audio DSP plug-in
  • Audio DSP plug-in (dual mode)
  • Video DSP plug-in
  • Video DSP plug-in (dual mode)

Each of the two basic sample plug-ins, Audio DSP and Video DSP, functions as a DirectX Media Object (DMO). That is, each sample plug-in implements the IMediaObject interface. Each of the two dual-mode sample plug-ins can function either as a DMO or as a Media Foundation Transform (MFT). That is, each dual-mode sample plug-in implements both the IMediaObject interface and the IMFTransform interface.

You can compile, link, register, and test the sample plug-in code. Then you can modify the generated sample code to create your own DSP plug-in.
