A simple to use interface to Video For Linux Two
This is a by-product of the undroidwish research allowing to use cheap USB webcams to capture images into Tk photo images. A man page is in http://www.androwish.org/index.html/wiki?name=v4l2+command , the source code is in http://www.ch-werner.de/AndroWish/v4l2-src.tar.gz

I have used your example to whip up a simple **viewing** script, from a selection of cameras attached to my Linux box. But what about: control of exposure/brightness/etc? The functionality of v4l2-ctl utility, effectively, are there provisions for listing and dynamically controlling parameters?
Also, I cannot figure out a way of capturing a stream, in addition to (or instead of, if I must) just showing it on the screen? Sort of a "record/stop recording" button? Could you provide a code sample, please?
