developed by Jerome Alet and a
team of developers at the University of Nice in France:
Boxtream is a mobile and autonomous audio and video streaming and recording studio. Of course, depending on your own hardware choices, the number and extent of capabilities and the quality of the final results may vary, but at least the software part should be versatile enough to accommodate even the most basic hardware.
Boxtream was mostly designed to stream live courses featuring a professor and his slides (or any other computer based output like software training, web browser, video player...), but can also be used to stream congresses, interviews and the like.
Boxtream uses a virtual smorgasbord of open-source components to achieve
its results. Scripting is done with the Python language, metadata is
stored in the XML format.
multimedia framework library is used for handling the audio/video
data and the
Icecast streaming media
server is used for media distribution.
Video and audio are encoded with
Ogg Theora and
Ogg Vorbis. The
Graphviz graph visualization
software is used for presenting a graphical view of the video
