Hi, I'm writing a program to take in video input using a frame grabber card, at the same time also reusing a program from another source.

however the problem is that the other program is using another brand of frame grabber. How can i change the coding of the program to fit to my brand of frame grabber?

Is it enough to just change the corresponding functions in the code?

By the way, i'm using Visual c++ and i'm trying to change from a Matrox MIL to a WinTV USB2 card. thanks!
