DirectShow Interfaces
The following table shows the reference entries for all Microsoft® DirectShow® COM interfaces supported in Microsoft Windows® CE .NET.
| Programming element | Description |
|---|---|
| IAMDevMemoryAllocator | Enables the creation of third-party memory allocators by using an on-board memory manager object. |
| IAMDevMemoryControl | Controls and identifies the on-board memory of codecs. |
| IAMMediaContent | Retrieves metadata from a stream. |
| IAMMediaContentEx | Retrieves metadata from a stream. |
| IAMovieSetup | Allow objects in a dynamic-link library (DLL) to be self-registering. |
| IAMPlayList | Provides access to descriptive information about a media playlist. |
| IAMPlayListItem | Provides the detailed property information for an item on a playlist. |
| IAMStreamControl | Allows applications to control individual stream components in a filter graph. |
| IAMStreamSelect | Controls which logical streams are played and retrieves information about them. |
| IAsyncReader | Allows multiple overlapped reads from different positions in the media stream. |
| IBaseFilter | Abstracts an object that has typed input and output connections and can be aggregated dynamically. |
| IBasicAudio | Supports the filter graph's audio component. |
| IBasicVideo | Supports the video properties of a generic video window. |
| IDirectDrawVideo | Allows an application to get details of the surface and any available hardware capabilities. |
| IDistributorNotify | Notifies plug-in distributors of changes in the filter graph state. |
| IDMOWrapperFilter | Enables applications to use DirectX Media Objects in a filter graph. |
| IEnumFilters | Returns the enumerator interface for filters. |
| IEnumMediaTypes | Enumerates the preferred formats for a pin. |
| IEnumPins | Returns the enumerator interface for pins. |
| IEnumRegFilters | Helps the Filter Graph Manager avoid loading filters when attempting to build a filter graph to render a given media type. |
| IFileSourceFilter | Sets the file name and media type of the media file that a source filter is to render. |
| IFilterGraph | Represents a graph of filters. |
| IFilterGraph2 | Adds new functionality to the IGraphBuilder and IFilterGraph interfaces. You should usually use IFilterGraph2 instead of the other two interfaces. |
| IFilterMapper | Allows properties of filters to be looked up during loading. |
| IFilterMapper2 | Registers and locates DirectShow filters with greater flexibility than IFilterMapper allows. Applications and filters should use IFilterMapper2 instead of IFilterMapper. |
| IGraphBuilder | Allows applications to call on the Filter Graph Manager to attempt to build a complete filter graph or parts of a filter graph given only partial information. |
| IGraphVersion | Notifies other objects, especially plug-in distributors, when the graph has changed. Provided by the Filter Graph Manager. |
| IMediaControl | Allows applications to control the streaming of media through the filters in the graph. |
| IMediaEvent | Supports event notification from the filter graph and filters within it to the application. |
| IMediaEventEx | Derives from IMediaEvent and adds a method that allows registration of a window to receive messages when events occur. |
| IMediaEventSink | Notifies events from filters. |
| IMediaFilter | Abstracts an object that processes time-based data streams and represents a multimedia device, possibly implemented in software. |
| IMediaPosition | It is recommended that you use the IMediaSeeking interface instead of IMediaPosition. This depreciated interface is no longer fully supported. |
| IMediaSample | Provides shared memory buffer functionality, holds some properties about the data, and holds a pointer to the data itself. |
| IMediaSample2 | Enables you to set and retrieve sample properties such as start and stop time that are defined in AM_SAMPLE2_PROPERTIES and sample flags defined in the AM_SAMPLE_PROPERTY_FLAGS structure. |
| IMediaSeeking | Improves on the IMediaPosition interface by allowing arbitrary formats for seekable units, such as frames, bytes, and 100-second units of time. |
| IMediaStream | Provides access to the characteristics of a media stream, such as the stream's media type and purpose identifier. It also has methods that create data samples. |
| IMemAllocator | Allocates IMediaSample blocks to be used for data transfer between pins. |
| IMemInputPin | Provides methods on an input pin to facilitate passing data and flush notifications from a connected output pin of an upstream filter. |
| IMultiMediaStream | Provides methods that control a multimedia stream and provide access to its underlying media streams. |
| INonDelegatingUnknown | Enables a class to support both nondelegating and delegating IUnknown interfaces in the same COM object. |
| IOverlay | Provides information so that a filter can write directly to video memory while placing the video in the correct window position. |
| IOverlayNotify | Provides an upstream filter, such as a decoder, with notifications of changes to the rendering window. |
| IPin | Represents a single, unidirectional connection point on a filter. |
| IQualityControl | Defines quality messages and allows a quality manager to install itself as the sink for these messages. |
| IQualProp | Returns information about the performance achieved — for example, the number of frames per second. |
| IReferenceClock | Represents a system reference clock to be implemented by a filter in the filter graph and used by other filters. |
| ISeekingPassThru | Instantiates and initializes a CRendererPosPassThru object to keep track of reference times and stream times. |
| IStreamSample | Provides control over the behavior of stream samples. |
| IVideoWindow | Supports the video window properties of a video renderer. |
| IVPBaseConfig | Enables a video port (VP) or overlay mixer filter to communicate with a VP driver (decoder) to set and retrieve configuration information. |
| IVPBaseNotify | Enables you to control the properties of a filter that uses a video port. |
| IVPConfig | Enables a video port (VP) or overlay mixer filter to communicate with a VP driver (decoder) to set and retrieve configuration information. |
| IVPNotify | Enables you to control the properties of a filter that uses a video port. |
