DirectShow sample apps

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

You can find the DirectShow sample apps in the Windows-classic-samples repository on GitHub.

The table below lists all of the DirectShow samples provided in that repo. For instructions on how to build the samples, refer to the documentation provided in the Windows SDK. If a topic exists describing a sample, then the first column of this table links to it.

Additional dependencies

Some of the samples link to the DirectShow base class library. To build those samples, first build the base class library. For more information, see DirectShow base classes. The base class library is required for all of the sample filters.

A few of the samples also require the DirectX SDK, in addition to the Windows SDK. To build those samples, you must install the DirectX SDK, and set the %DXSDK\_DIR% environment variable equal to your DirectX SDK installation path.

Many of the DirectShow samples use a set of common headers and source files located in the directrory \[SDK Root\]Samples\Multimedia\DirectShow\Common. If you copy a sample folder to another directory, then make sure to copy the Common folder as well.
