intensity pro 4K and SDK 10.5.1

Hello everyone,

I'm used to program with intensity pro for 3 years ( SDK 9.5, windows seven 32 bits, DELL motherboard)

This code work fine with intensity pro, unfortunately it fails with intensity pro 4K (SDK 10.5.1, windows seven 64 bits, DELL motherboard)

Code: Select all

   HRESULT                result;
   IDeckLinkIterator      *deckLinkIterator = NULL;
   IDeckLink              *deckLink = NULL;
   IDeckLinkConfiguration *deckLinkConfig = NULL;
   IDeckLinkInput         *deckLinkInput = NULL;
   
   result = CoCreateInstance(CLSID_CDeckLinkIterator, NULL, CLSCTX_ALL, IID_IDeckLinkIterator, (void**)&deckLinkIterator);
   //result = S_OK
   
   result = deckLinkIterator->Next(&deckLink);
   //result = S_OK   
   
   result = deckLink->QueryInterface(IID_IDeckLinkConfiguration, (void**)&deckLinkConfig);
   //result = S_OK

   
   result = deckLinkConfig->SetInt(bmdDeckLinkConfigVideoInputConnection, bmdModeHD1080i50);
   //result = S_OK
   
   result = deckLink->QueryInterface(IID_IDeckLinkInput, (void**)&deckLinkInput);
   //result = S_OK

   BMDDisplayModeSupport theresult;
   deckLinkInput->DoesSupportVideoMode(bmdModeHD1080i50, bmdFormat10BitRGB, bmdVideoInputFlagDefault, &theresult, NULL);
   //theresult = 1 (bmdDisplayModeNotSupported)
   
   result = deckLinkInput->EnableVideoInput(bmdModeHD1080i50, bmdFormat10BitRGB, 1);
   //result = E_ACCESSDENIED

Of course I'm admin of this station

Any ideas?
Thank you in advance.
