mfobjects.h contains the following programming interfaces:

Interfaces

IMF2DBuffer Represents a buffer that contains a two-dimensional surface, such as a video frame. (IMF2DBuffer)
IMF2DBuffer2 Represents a buffer that contains a two-dimensional surface, such as a video frame. (IMF2DBuffer2)
IMFActivate Enables the application to defer the creation of an object.
IMFAsyncCallback Callback interface to notify the application when an asynchronous method completes. (IMFAsyncCallback)
IMFAsyncCallbackLogging Provides logging information about the parent object the async callback is associated with.
IMFAsyncResult Provides information about the result of an asynchronous operation. (IMFAsyncResult)
IMFAttributes Provides a generic way to store key/value pairs on an object.
IMFAudioMediaType IMFAudioMediaType is no longer available for use as of Windows 7.
IMFByteStream Represents a byte stream from some data source, which might be a local file, a network file, or some other source.
IMFByteStreamProxyClassFactory Creates a proxy to a byte stream. (IMFByteStreamProxyClassFactory)
IMFCollection Represents a generic collection of IUnknown pointers.
IMFDXGIBuffer Represents a buffer that contains a Microsoft DirectX Graphics Infrastructure (DXGI)surface.
IMFDXGIDeviceManager Enables two threads to share the same Microsoft Direct3D 11 device.
IMFMediaBuffer Represents a block of memory that contains media data.
IMFMediaEvent Represents an event generated by a Media Foundation object. Use this interface to get information about the event.
IMFMediaEventGenerator Retrieves events from any Media Foundation object that generates events.
IMFMediaEventQueue Provides an event queue for applications that need to implement the IMFMediaEventGenerator interface.
IMFMediaType Represents a description of a media format.
IMFMuxStreamAttributesManager Provides access to the IMFAttributes of the substreams of a multiplexed media source.
IMFMuxStreamMediaTypeManager Enables the management of stream configurations for a multiplexed media source. A stream configuration defines a set of substreams that can be included the multiplexed output.
IMFMuxStreamSampleManager Provides the ability to retrieve IMFSample objects for individual substreams within the output of a multiplexed media source.
IMFPluginControl Controls how media sources and transforms are enumerated in Microsoft Media Foundation. (IMFPluginControl)
IMFPluginControl2 Controls how media sources and transforms are enumerated in Microsoft Media Foundation. (IMFPluginControl2)
IMFRemoteAsyncCallback Used by the Microsoft Media Foundation proxy/stub DLL to marshal certain asynchronous method calls across process boundaries.Applications do not use or implement this interface.
IMFSample Represents a media sample, which is a container object for media data.
IMFSampleOutputStream Writes media samples to a byte stream.
IMFVideoMediaType Represents a description of a video format.

Functions
