DirectShow and Windows Media
As an alternative to using the Windows Media Format SDK exclusively, applications can also read and write Windows Media-based content by using the Microsoft® DirectShow® streaming architecture, as described in the following sections.
| Section | Description |
|---|---|
| About DirectShow | Describes DirectShow in general terms and tells where to get more information about it. |
| Why Use DirectShow? | Describes how DirectShow simplifies certain tasks in the creation and playback of Windows Media–based content. |
| Reading ASF Files in DirectShow | Describes how to play ASF files using DirectShow. |
| Creating ASF Files in DirectShow | Describes how to create ASF files using DirectShow. |
| WMT_STATUS Event Notification in DirectShow | Describes which WMT_STATUS events are handled by the ASF Reader and ASF Writer filters, and how applications can receive those events. |
| DRM Support in DirectShow | Describes how to read and write DRM-protected files through DirectShow. |
| DirectShow QASF Reference | Contains the reference documentation for the DirectShow components that support Windows Media. |
Three sample applications in the SDK illustrate the use of DirectShow: DSCopy, DSPlay, and DSSeekFM. For more information, see Sample Applications.
Note
Applications that use the QASF components included in this SDK require the Microsoft DirectX® 8.1 or later SDK runtime to be installed on Windows® 2000, Windows 98, and Windows 95 systems. Specifically, this runtime is required by the DMO Wrapper filter which hosts the Windows Media codecs in a DirectShow filter graph.
