IStreamBuilder Interface

The IStreamBuilder interface enables an output pin to notify the filter graph manager that the pin itself will build the downstream section of the filter graph. Output pins with special connection needs can implement this interface to override the default pin connection process used by the filter graph manager.

In addition to the methods inherited from IUnknown, the IStreamBuilder interface exposes the following methods.

Method Description
Render Completes rendering of the stream originating with this pin. This can involve adding filters to the filter graph and connecting them.
Backout Undoes steps taken in Render. This includes disconnecting and removing any filters that were added inside Render.

Requirements

Header: Declared in Strmif.h; include Dshow.h.

Library: Use Strmiids.lib.
