libannodex 0.6.2 Release
-------------------------
libannodex is a C library providing a simple programming interface for reading
and writing Annodex media. Annodex is an open standards based technology that
extends the World Wide Web's hyperlinking, searching, and compositing
infrastructure to time-continuous data, enabling video surfing, searching for
clips of audio and video files using ordinary Web search engines, and
on-the-fly composition of a video on a Web server from previously annodexed
clips. For more information on Annodex, see http://www.annodex.net/
This release is available as a source tarball at:
