The following table shows the reference entries for all supported Microsoft DirectShow COM interfaces.

Programming element	Description
IAMAudioRendererStats Interface	Retrieves statistical performance information from an audio renderer filter.
IAMBufferNegotiation Interface	Enables an application to request how many buffers a filter creates and the buffer size.
IAMCameraControl Interface	Provides local or remote control over a camera.
IAMDroppedFrames Interface	Retrieves performance information from a video capture filter, such as how many frames were dropped and how many frames were delivered.
IAMExtendedSeeking Interface	Provides methods for seeking to markers in a Windows Media stream and for modifying the playback speed.
IAMFilterMiscFlags Interface	Indicates whether a filter is a source filter or a renderer.
IAMMediaContent Interface	Retrieves metadata from a stream.
IAMovieSetup Interface	Allow objects in a dynamic-link library (DLL) to be self-registering.
IAMStreamConfig Interface	Enables applications to query for the types of formats a filter supports on its output pin and to set the format that the pin will offer to its downstream connecting pin.
IAMStreamControl Interface	Allows applications to control individual stream components in a filter graph.
IAMStreamSelect Interface	Controls which logical streams are played and retrieves information about them.
IAMVideoCompression Interface	Sets and retrieves video compression properties.
IAMVideoControl Interface	Enables you to flip a picture horizontally or vertically, set up a stream so it can capture from an external trigger (such as a camera button that the user pushes), simulate an external trigger in software, and list the available frame rates.
IAMVideoProcAmp Interface	Enables an application to adjust the qualities of an incoming video signal, such as brightness, contrast, hue, saturation, gamma, and sharpness.
IAMVideoRendererMode Interface	Manages the rendering mode used by the DirectShow Video Renderer Filter.
IAMVideoTransformComponent Interface	Implemented by video transform filters that can efficiently perform rotation and scaling so that downstream filters, such as the video renderer, can use its capabilities if they are needed.
IAMVideoTransform Interface	Implemented by applications to control video rotation and scaling parameters.
IAsyncReader Interface	Allows multiple overlapped reads from different positions in the media stream.
IAudioRenderer Interface	Allows adjustments to the audio renderer.
IAudioRendererWaveOut Interface	Controls the Audio Renderer (WaveOut) Filter, which uses the Waveform Audio API to render sound.
IBaseFilter Interface	Abstracts an object that has typed input and output connections and can be dynamically aggregated.
IBasicAudio Interface	Supports the filter graph's audio component.
IBasicVideo Interface	Supports the video properties of a generic video window.
IBuffering Interface	Allows you to control the size of the buffer filter in a capture graph.
ICaptureGraphBuilder2 Interface	Provides methods for building capture graphs, and other custom filter graphs. The Capture Graph Builder object implements this interface.
IDirectDrawVideo Interface	Allows an application to get details of the surface and any available hardware capabilities.
IDistributorNotify Interface	Notifies plug-in distributors of changes in the filter graph state.
IDMOWrapperFilter Interface	Enables applications to use DirectX Media Objects in a filter graph.
IEnumFilters Interface	Enumerates all filters in the graph.
IEnumMediaTypes Interface	Enumerates the preferred formats for a pin.
IEnumPins Interface	Returns the enumerator interface for pins.

IFileSinkFilter Interface	The IFileSinkFilter2 Interface replaces this interface and inherits from it.
IFileSinkFilter2 Interface	Writes media streams to a file.
IFileSourceFilter Interface	Sets the file name and media type of the media file that a source filter is to render.
IFilterGraph Interface	Represents a graph of filters.
IFilterGraph2 Interface	Adds new functionality to the IGraphBuilder and IFilterGraph interfaces. IFilterGraph2 is preferred over the two preceding interfaces.
IFilterMapper Interface	Allows properties of filters to be looked up during loading.
IGraphBuilder Interface	Allows applications to call on the Filter Graph Manager to attempt to build a complete filter graph or parts of a filter graph with only partial information.
IGraphVersion Interface	Notifies other objects, especially plug-in distributors, when the graph has changed. Provided by the Filter Graph Manager.
IImageSinkFilter Interface	Sets the properties of the image sink filter.
IKsPropertySet Interface	Sets and retrieves device properties on drivers, and between software components.
IMediaControl Interface	Allows applications to control media streaming through the filters in the graph.
IMediaEvent Interface	Supports event notification from the filter graph and filters within it to the application.
IMediaEventEx Interface	Derives from IMediaEvent and adds a method that allows registration of a window to receive messages when events occur.
IMediaEventSink Interface	Notifies events from filters.
IMediaFilter Interface	Abstracts an object that processes time-based data streams and represents a multimedia device, possibly implemented in software.
IMediaPosition Interface	It is recommended that you use the IMediaSeeking interface instead of IMediaPosition. This depreciated interface is no longer fully supported.
IMediaSample Interface	Provides shared memory buffer functionality; holds some properties about the data; and holds a pointer to the data itself.
IMediaSample2 Interface	Enables you to set and retrieve sample properties, such as start and stop time, that are defined in an AM_SAMPLE2_PROPERTIES structure and sample flags defined in the AM_SAMPLE_PROPERTY_FLAGS enumeration.
IMediaSeeking Interface	Improves the IMediaPosition interface by allowing arbitrary formats for seekable units, such as frames, bytes, and 100-second units of time.
IMemAllocator Interface	Allocates IMediaSample blocks to be used for data transfer between pins.
IMemInputPin Interface	Provides methods on an input pin to facilitate passing data and flush notifications from a connected output pin of an upstream filter.
INonDelegatingUnknown Interface	Enables a class to support both nondelegating and delegating IUnknown interfaces in the same COM object.
IOverlay Interface	Provides information so that a filter can write directly to video memory while placing the video in the correct window position.
IOverlayNotify Interface	Provides an upstream filter, such as a decoder, with notifications of changes to the rendering window.
IPin Interface	Represents a single, unidirectional connection point on a filter.
IQualityControl Interface	Defines quality messages and allows a quality manager to install itself as the sink for these messages.
IQualProp Interface	Returns information about the performance achieved; for example, the number of frames per second.
IReferenceClock Interface	Represents a system reference clock to be implemented by a filter in the filter graph and used by other filters.
ISeekingPassThru Interface	Instantiates and initializes a CRendererPosPassThru::CRendererPosPassThru object to keep track of reference times and stream times.
ISmartTee Interface	Supports querying for the presence of the Smart Tee Filter in the filter graph.
IVideoWindow Interface	Supports the video window properties of a video renderer.
