Linux Stopmotion is a program for creating stop-motion animation movies.

I had to apply a small patch to make grabbing images from webcam work
(using uvccapture). I find it odd that it didn't work without the patch,
seeing that Arch Linux also have the v0.8.0 version, but with no patch.
Latest Ubuntu (14.04) has v0.7.2, which is unaffected.
