Description

OpenCV should have an API to enumerate cameras. Without it, writing programs that support non-fixed hardware is not possible.

The point of this API is to retrieve information about the cameras attached to the system:
- NumberOf
- Name of each camera (can be used for user-selection in a GUI)
- Resolution of each camera
- other properties.

It will then be possible to write programs (f.i. surveillance software) that support 1 to any number of cameras instead of requiring a given number of cameras.
