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.
