DirectShow Classes (Windows Embedded CE 6.0)

CAggDrawSurface Class

Aggregates an IDirectDrawSurface interface.

CAMMsgEvent Class

A wrapper for event objects that do message processing.

CAMThread Class

An abstract class, which is a worker thread class that provides creation, synchronization, and communication with a worker thread.

CBaseAllocator Class

An abstract base class that implements the basic mechanisms for an allocator with a fixed number of fixed-size buffers.

CBaseControlVideo Class

Implements the IBasicVideo Interface dual interface and controls the video properties of a generic video window.

CBaseDispatch Class

A base class that implements the IDispatch interface for use in a dual interface.

CBaseInputPin Class

An abstract base class derived from CBasePin Class that adds support for IMemInputPin Interface in addition to the IPin Interface interface support provided by CBasePin.

CBaseMediaFilter Class

An abstract base class that provides support for the IMediaFilter Interface interface.

The CBaseMediaFilter class handles State_Stopped, State_Paused, and State_Running state transitions.

CBaseOutputPin Class

An abstract base class derived from the CBasePin Class class that provides support for the common memory transport.

CBasePropertyPage Class

An abstract class for implementing a property page.

CBaseRenderer Class

The base renderer class for writing renderers. This class handles a single input pin, all state changes, and synchronization.

CBaseVideoWindow Class

Handles the IDispatch component of the IVideoWindow interface and leaves the IVideoWindow properties and methods as a pure virtual function.

CCritSec Class

Provides intra-process synchronization.

CDispBasic Class

An internal class used to implement the CDisp Class class.

CEnumPins Class

Supports the IEnumPins Interface enumeration interface by calling CBaseFilter Class methods.

CGenericList Class

A template class that allows for a type-specific implementation of a list.

CLoadDirectDraw Class

Manages loading and unloading the Microsoft DirectDraw® library and creating the initial IDirectDraw interface.

CMediaEvent Class

The CMediaEvent class provides base class implementation of the IDispatch methods of the dual-interface IMediaEvent Interface.

It leaves the properties and methods of the IMediaEvent interface as a pure virtual function.

CMediaSample Class

Represents a buffer object that supports the IMediaSample Interface interface.

CMemAllocator Class

Provides support for IMemAllocator Interface by using the new operator to allocate memory.

CMsgThread Class

A worker thread class that queues requests to the queuing thread for completion asynchronously.

COutputQueue Class

Output pins use COutputQueue to send samples to another filter by using the local memory-based transport (that is, to input pins that support the IMemInputPin Interface interface).

CPosPassThru Class

A utility class that handles the IMediaPosition Interface and IMediaSeeking Interface interfaces for single-input pin renderers and transform filters.

CQueue Class

Implements a simple queue abstract data type.

The queue contains a finite number of objects, and a semaphore controls access to these objects.

CRendererInputPin Class

Channels calls to the rendering filter.

CSource Class

This class and its corresponding class, CSourceStream Class, simplify the construction of source filters that produce continuous streams of data comparable to the way the CTransformFilter Class class assists in the creation of transform filters.

CSourceSeeking Class

An abstract class that assists source filters with the implementation of IMediaSeeking Interface interface methods.

This class enables a source filter to handle calls that change the start and stop positions in the media stream and the playback rate.

CSystemClock Class

Implements a system clock that provides time information and timing signals to an application.

CTransformInputPin Class

Implements the input pin of a simple transform filter.

CUnknown Class

All DirectShow Component Object Model (COM) objects derive from the CUnknown abstract base class.

This class facilitates the creation of simple COM objects that you can combine with other COM objects to support multiple interfaces.

CBaseWindow Class

Creates a window and a worker thread.

The worker thread pulls messages from the window's input queue and dispatches them as appropriate.

CTransInPlaceInputPin Class

Implements the input pin to transform data in place rather than making a copy of it.

CVideoTransformFilter Class

Primarily a base class for AVI decompressor filters.

It is based on a copying transform class and assumes that the output buffer will likely be a video buffer or DirectDraw buffer, although this could be used as a base class for other types of transform filters.
