The RenderOutputPins method creates the previewing portion of the filter graph.
This method takes no parameters.
If the method fails, an error is raised, and Err.Number can be set to one of the following values:
|E_RENDER_ENGINE_IS_BROKEN||Operation failed because project was not rendered successfully.|
Before calling this method, call ConnectFrontEnd to build the front end of the graph. To perform an operation other than preview, do not call this method. Instead, call GetGroupOutputPin to obtain pointers to the output pins.
