Camera realtime capture, video viewing and saving software(repost)(repost)

I need C++ support. I have working C++ project which can capture USB 3.0 cameras. I need to modifiels this code. With USB 2.0 and Visual Basic I did this projects now I want similar project with this C++ code and USB 3.0. For testing I will give permision to remote connect to my computer which have usb 3.0 , video capture card and camera. In addition rar file I send C++ working source codes, Visual Basic 6.0 sample project source codes and VB code setup. VB version is (both setup and VB source codes) protype for this project. I want same view and function program with C++. VB version is working USB 2.0 cameras (component is CapturePRO3, [login to view URL]) C++ will work USB 3.0. For this I plan to use Blackmagic Intensity Shuttle SDK ([login to view URL]). I setup this hardware to my computer, I can capture HD videos with this SDK. Now I need C++ support to modifield this SDK
