Capture stills from avi on Windows

Question

I need to capture stills from avi files. I also need to know avi file duration. The Platform is Windows, the language is C++ (with Qt library). I don't know much about DirectShow or Qt Phonon and I have no time to learn any of them. So I'm looking for ready made solutions. Maybe there is some open source project where I can find some sources for inspiration? Or maybe there is some free dll which can do the job?

Answer 1

There is http://ffmpeg.org/. There are windows C++ sources.
