ASF Script Streams in DirectShow
When the WM ASF Reader filter is given a file that includes a stream of type WMMEDIATYPE_Script, it creates an output pin for it that can be connected to the Internal Script Command Renderer filter. When you call IGraphBuilder::RenderFile, that filter is automatically added to the graph and connected. When the Internal Script Command Renderer receives a sample containing a script command, it fires an EC_OLE_EVENT event whose lParam contains the script. The application is entirely responsible for handling this event.
