Freeseer
Freeseer is a cross-platform screencasting application suite released as free and open source software. Freeseer is a project of the Free and Open Source Software Learning Centre (FOSSLC), a not-for-profit organization.
Its primary purpose is conference recording and has been used at conferences like OSGeo's FOSS4G, FSOSS, and more.
The software renders videos in an Ogg format. Its video source options are USB (e.g. internal/external webcam) or desktop. Freeseer consists of three different dependent programs: a recording tool (which is the main tool), a configuration tool, and a talk-list editor.
