How to read input from a webcam in C++?

Question

is it possible to read data from a generic webcam in C++ as you would from a stream object? Is there a common API or standard that works with all webcams?

I'm talking about C++ in *nix environment.

Thanks in advance.

Solution 1

For linux, V4L. AFAIR, BSD uses the same codebase. I do not know about the others...

Solution 2

In Linux, webcams are supported using Video4Linux. Take a look at the userspace API and an Video4Linux introduction.

Solution 3

You might wanna check if webcams are TWAIN compatible and use their apis to do that.
