I've generated C++ from a graph that includes LEADTOOLS H.264 filters, and the generated source includes a reference to 'GUID1' which appears to be a placeholder of some kind since upon compilation it's not resolved. Any hints or suggestions for what GUID1 should be? The Graph image and generated source are below.
Here is the generated source. The object of concern is Sample Grabber 0002:
//Don't forget to change project settings:
//1. C++: add include path to DirectShow include folder (such as c:\dxsdk\include)
//2. Link: add link path to DirectShow lib folder (such as c:\dxsdk\lib).
//3. Link: add strmiids.lib and quartz.lib
#include "stdafx.h"
#include <DShow.h>
#include <atlbase.h>
#include <initguid.h>
#include <dvdmedia.h>
