Freeseer Freeseer

by the Free and Open Source Software Learning Centre (FOSSLC)

Freeseer is a free and open source screencasting application. Its primary purpose is capturing or streaming video at conferences.

It's been successfully used to capture presentations, demos, training material, and other videos. It can easily handle very large conferences with many talks using varied hardware and operating systems.

It is one of a few such tools that can also record VGA output or video from external sources such as FireWire, USB, S-Video, or RCA.

Freeseer is written in Python, uses Qt4 for its GUI, and Gstreamer for video/audio processing.

Freeseer is based on open standards and supports royalty free audio and video codecs.
