The IRenderEngine interface renders a DirectShow Editing Services (DES) project by constructing a filter graph from a
DES provides two components that implement this interface:
The smart render engine also supports the ISmartRenderEngine interface.
Although an application can create a filter graph and pass it to a render engine, the typical scenario is for the render engine to create the filter graph. Building the graph is a two-stage process. First, build the front end by calling the IRenderEngine::ConnectFrontEnd method. Then connect the output pins on the front end to the desired rendering filters:
In addition to the methods inherited from IUnknown, the IRenderEngine interface exposes the following methods.
|ConnectFrontEnd||Builds the front end of the filter graph from the current timeline.|
|GetFilterGraph||Retrieves the filter graph that the render engine has constructed, if any.|
|GetGroupOutputPin||Retrieves the output pin for the specified group.|
|GetTimelineObject||Retrieves the timeline that the render engine is currently using.|
|GetVendorString||Retrieves the vendor string.|
|RenderOutputPins||Creates the previewing portion of the filter graph.|
|ScrapIt||Discards the render engine's filter graph and all associated objects.|
|SetDynamicReconnectLevel||Sets the level of dynamic reconnection during rendering.|
|SetFilterGraph||Specifies a filter graph for the render engine to use.|
|SetRenderRange||Sets the range of time to be rendered.|
|SetRenderRange2||Sets the range of time to be rendered, as a double.|
|SetSourceNameValidation||Specifies how the render engine validates file names.|
|SetTimelineObject||Sets the timeline for the render engine to use.|
