Cheese is a nice lightweight webcam app that can record video and take pictures. It uses the gstreamer backend, and Stskeeps got it working with the tablet camera in Deblet.

The Ubuntu repositories have something called cheese-hildon. That suggests that someone's hildonized cheese for ubuntu-mid. There's even an armel binary, but with a truckload of ubuntu-specific dependencies.

I would love to see if someone could get this compiled for maemo.
