It automatically handles time offsets for files containing + Theora, Speex, Vorbis, FLAC and CMML. + + r1092: fix a bug in raw seeking, where doing a raw seek by bytes + and back again by time (to the original time point) hadn't + invalidated the cached time offset, hence the second seek was + considered unnecessary and skipped. This change correctly + invalidates the cached time offset when doing a raw byte seek. + + + * unnecessary optimisations in oggzrip tool + ------------------------------------------- + + Optimised packet filtering: filtering decisions are now made at the + start of each logical bitstream, not at every packet. Additionally, + the hardcoded limit of extracting no more than 64 logical bitstreams + from the input file was removed. + + The man page for oggzrip(1) can be read online at: + + http://www.annodex.net/cgi-bin/man/man2html?query=oggzrip + + +About Oggz +---------- + +Oggz comprises liboggz and the command-line tools oggzinfo, oggzdump, +oggzdiff, oggzmerge, oggzrip and oggz-validate. + +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. + The entire test suite can be run under valgrind if available. + + * 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, FLAC, + CMML and Ogg Skeleton 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: + + * oggzinfo: Display information about one or more Ogg files and + their 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. + + * oggzrip: Extract one or more logical bitstreams from an Ogg file. + + * oggz-validate: Validate the Ogg framing of one or more files. + +License +------- + +Oggz is Free Software, available under a BSD style license. + +More information is available online at the Oggz homepage: + + http://www.annodex.net/software/liboggz/ + +enjoy :) + +-- +Conrad Parker +Senior Software Engineer, Continuous Media Web, CSIRO Australia +http://www.annodex.net/ http://www.ict.csiro.au/cmweb/ -- GitLab
