Simple image capture with camera

edit

I am trying to develop a small C application with below specs:

1. Capture image (JPEG / BMP) from a specific camera based on VID / PID
2. Cross platform

Although the implementation looks to be simple. For noob who started to work with CAMERA . This implementation looks little hard.

I tried OPENCV to capture image was successful.But, I see that I was not able to access a specific camera based on its (VID / PID ).

Thought LIBUVC should help. If somebody could helpme with sequential pointers & examples it could be a real starter for my simple APP devlopment
