A video editor based on a human writeable script language.
A script language describes how multiple media sources should be combined. Stream-compiler takes this textual description and creates a single video output.
All the heavy lifting of actually decoding, encoding, compositing, etc is done using GStreamer (GST) and GStreamer Editing Services (GES).
See also ges-launch-1.0 that expose all the features of GES but in a not so
user friendly format.
