Hello,
I just hacked a simple video app, using:
http://mdamt.net/node/174
http://www.maemo.org/platform/docs/h..._api_bora.html

It's has only basic functionality, it can record sound and video, pause, restart, and save. The quality is poor, but still nice. The codex for encoding is made for small devices and doesn't work well for high resolution.
I wanted to download the vmware image to recompile some gstreamer plugins, but it's a bittorrent and they bittorrent trackers on my network.

you can download the app here:

You need python to run this program!
