LTMM DirectShow Filter List Utility

The "LTMM DirectShow Filter List Utility" is an application that allows the user to enumerate all of the registered DirectShow filters and copy filter information to the clipboard. This is especially useful for copying the filter "Display Name" to your application and changing the filter's Merit field. This allows the user to directly assign a compressor, device, or processor to an object. For instance, to assign the "LEAD Video Emboss Filter" to the convert object proceed as follows:

1. Run the "LTMM DirectShow Filter List Utility"

2. Select the "LEAD Video Emboss Filter"

   

3. Click the Copy button to the right of the "Display Name" field.

4. Paste the "Display Name" into your code:
   LPCWSTR pszEmboss = L"@device:sw:{E526D606-22E7-494C-B81E-AC0A94BFE603}{E2B7DB17-38C5-11D5-91F6-00104BDB8FF9}";

5. Add the emboss processor to the convert object:

   C API

   IltmmConvert* pConvert; // initialized elsewhere   
   IltmmProcessors* pProcessors; // registered processor collection   
   IltmmProcessors* pSelProcessors; // selected processor collection   
   long index;   
   BSTR bstr;   
   // get the registered processors collection   
   IltmmConvert_get_VideoProcessors get_VideoProcessors(pConvert, &pProcessors);   
   // find the processor index by name   
   bstr = SysAllocString(pszEmboss);   
   IltmmProcessors_Find Find(pProcessors, bstr, &index);   
   SysFreeString(bstr);   
   // get the processor interface   
   IltmmProcessors_Item Item(pProcessors, index, &pProcessor);   
   // get the selected processors collection   
   IltmmConvert_get_SelectedVideoProcessors get_SelectedVideoProcessors (pConvert, &pSelProcessors);   
   // add the processor to the selected processors collection   
   IltmmProcessors_Add Add(pSelProcessors, pProcessor, -1);   
   // release interfaces   
   IUnknown_Release(pProcessor);   
   IUnknown_Release(pSelProcessors);   
   IUnknown_Release(pProcessors); 

   C++

   IltmmConvert* pConvert; // initialized elsewhere   
   IltmmProcessors* pProcessors; // registered processor collection   
   IltmmProcessors* pSelProcessors; // selected processor collection   
   long index;   
   BSTR bstr;   
   // get the registered processors collection   
   pConvert->get_VideoProcessors (&pProcessors);   
   // find the processor index by name   
   bstr = SysAllocString(pszEmboss);   
   pProcessors->Find (bstr, &index);   
   SysFreeString(bstr);   
   // get the processor interface   
   pProcessors->Item (index, &pProcessor);   
   // get the selected processors collection   
   pConvert->get_SelectedVideoProcessors (&pSelProcessors);   
   // add the processor to the selected processors collection   
   pSelProcessors->Add(pProcessor, -1);   
   // release interfaces   
   pProcessor->Release();   
   pSelProcessors->Release();   
   pProcessors->Release();
