[linux-audio-announce] liboggz 0.8.5 Released

Oggz 0.8.5 Release ------------------ liboggz is a C library providing a simple programming interface for reading and writing Ogg files and streams. Ogg is an interleaving data container developed by Monty at Xiph.Org, originally to support the Ogg Vorbis audio format. This release is available as a source tarball at: http://www.annodex.net/software/liboggz/download/liboggz-0.8.5.tar.gz New in this release: * new oggzmerge tool, for time-wise interleaving of bitstreams. Via OggzAuto, merges files containing any number of Vorbis, Speex, Theora and Annodex bitstreams automatically. * updated support for Win32 * added OggzReadPage API * many improvements to seeking behaviour * added seek-stress example program * fixed theora keyframe shift interpretation in oggz_auto About Oggz ---------- Oggz comprises liboggz and the command-line tools oggzdump, oggzdiff and oggzmerge. liboggz supports the flexibility afforded by the Ogg file format while presenting the following API niceties: * Full API documentation. * Comprehensive test suite of read, write and seeking behavior. * Developed and tested on GNU/Linux, Darwin/MacOSX, Win32 and Symbian OS. May work on other Unix-like systems via GNU autoconf. For Win32: nmake Makefiles, Visual Studio .NET 2003 solution files and Visual C++ 6.0 workspace files are provided in the source distribution. * Strict adherence to the formatting requirements of Ogg bitstreams, to ensure that only valid bitstreams are generated; writes can fail if you try to write illegally structured packets. * A simple, callback based open/read/close or open/write/close interface to raw Ogg files. * Writing automatically interleaves with packet queuing, and provides callback based notification when this queue is empty * A customisable seeking abstraction for seeking on multitrack Ogg data. Seeking works easily and reliably on multitrack and multi-codec streams, and can transparently parse Theora, Speex, Vorbis and Annodex headers without requiring linking to those libraries. This allows efficient use on servers and other devices that need to parse and seek within Ogg files, but do not need to do a full media decode. Full documentation of the liboggz API, customization and installation, and mux and demux examples can be read online at: http://www.annodex.net/software/liboggz/html/ Tools ----- The Oggz source tarball also contains the following command-line tools, which are useful for debugging and testing Ogg bitstreams: * oggzdump: Hexdump packets of an Ogg file, or revert an Ogg file from such a hexdump. * oggzdiff: Hexdump the packets of two Ogg files and output differences Oggz is Free Software, available under a BSD-style license. * oggzmerge: Merge Ogg files together, interleaving pages in order of presentation time.
