libannodex 0.6.0 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:
http://www.annodex.net/software/libannodex/download/libannodex-0.6.0.tar.gz
New in this release:
Support for Annodex version 3:
* Support for reading and writing Ogg Skeleton and CMML binary
headers
* Support for recomposition from keyframe offsets, using
granuleshift clues from Theora and CMML headers. This provides
efficient playback of video and the current CMML clip.
* Read-only support for reading and importing Annodex v2 content
to allow existing content to be recomposed in v3 format without
modification.
General improvements and bugfixes:
* Updates to xtag to gracefully ignore XML comments and processing
directives, and new internal API documentation in xtag.h
* use liboggz's default STRICT mode when writing to ensure adherence
to Ogg mapping constraints
* added accessor functions anx_get_presentation_time() and
anx_get_basetime()
* updates to anxenc, anxrip and anxinfo as required
* updated libtool shared version info to 1:0:1
