What’s the simplest way in Ubuntu 11.10 to programmatically guide (either from Bash or Python) the user to capture a webcam photo of themselves?

I can launch a simple app like Cheese, but I don’t see an easy way to immediately detect or retrieve the photo it captures. I can also access and record the webcam stream directly via OpenCV, but I’d have to reinvent the GUI to communicate with the user.

Is there any kind of script that’s a happy medium, where I can launch it, and it prints on stdout the filename of the image the user took?

    If you want to do this via Python, it looks like you have a few options. The Pygame library has the ability to access cameras.

    If that’s unsatisfactory, you can go much lower level and access the Video 4 Linux 2 API directly using ioctl calls using Python’s fcntl library.
