Multimedia Streaming Interfaces
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
Note
These APIs are deprecated. Applications should use the Sample Grabber filter or implement a custom filter to get data from a DirectShow filter graph.
This section contains reference entries for all the multimedia streaming interfaces and their methods, including those that Microsoft DirectShow supports.
| Interface | Description |
|---|---|
| IAMMediaStream | Handles the internal connections between DirectShow filters and filter graphs in applications that use multimedia streaming. |
| IAMMediaTypeSample | Contains methods for manipulating stream samples with arbitrary media types. |
| IAMMediaTypeStream | Contains methods for creating multimedia streams with arbitrary media types. |
| IAMMultiMediaStream | Exposes DirectShow functionality to multimedia stream developers. |
| IAudioData | Provides methods that enable applications to set and get the underlying audio data that audio streams will reference. |
| IAudioMediaStream | Controls audio media streams by providing methods that set and get the stream's format. |
| IAudioStreamSample | Retrieves information from the underlying IAudioData data objects. |
| IDirectDrawMediaStream | Controls media streams that appear on Microsoft® DirectDraw® surfaces. |
| IDirectDrawStreamSample | Provides methods that set and retrieve pointers to the DirectDraw surface associated with the current stream sample. |
| IMediaStream | Provides access to the characteristics of a media stream, such as the stream's media type and purpose ID. It also has methods that create data samples. |
| IMediaStreamFilter | Supported by the Media Stream filter, which is used internally by the multimedia stream object. . |
| IMemoryData | Contains methods that set and retrieve memory data on audio data objects. |
| IMultiMediaStream | Provides methods that control a multimedia stream and provide access to its underlying media streams. |
| IStreamSample | Provides control over the behavior of stream samples. |
