Specifically, the 'vorbis' CVS module contains only the libvorbis, libvorbisfile, and libvorbisenc libraries. Because Ogg bitstreams are to be used by other Ogg codecs, Ogg framing and streaming functionality is now in libogg (the 'ogg' CVS module). Vorbis utilities are in 'vorbis-tools' and various player plugins are in 'vorbis-plugins'. For now, you'll need to check out these other modules seperately. (Note: the xmms plugin is in the xmms CVS tree in xmms/Input/vorbis.) Secondly, the Ogg/Vorbis build systems now use automake. Instead of './configure; make', the proper build sequence (in each module) is './autogen.sh; make'. You will also need the newest versions of autoconf, automake, and libtool in order to compile vorbis from CVS. configure scripts are provided for you in tarball distributions. WHAT'S HERE: This source distribution includes libvorbis and an example encoder/player to demonstrate use of libvorbis and documentation on the Ogg Vorbis audio coding format. Directory: ./lib The source for the libraries, a BSD-license implementation of the public domain Ogg Vorbis audio encoding format. ./include Library API headers ./debian Rules/spec files for building Debian .deb packages ./doc Vorbis documentation ./examples Example code illustrating programmatic use of libvorbis, libvorbisfile and libvorbisenc ./mac Codewarrior project files and build tweaks for MacOS. ./macosx Project files for MacOS X. ./win32 Win32 projects files and build automation ./vq Internal utilities for training/building new LSP/residue and auxiliary codebooks. WHAT IS VORBIS: Vorbis is a general purpose audio and music encoding format contemporary to MPEG-4's AAC and TwinVQ, the next generation beyond MPEG audio layer 3. Unlike the MPEG sponsored formats (and other proprietary formats such as RealAudio G2 and Windows' flavor of the month), the Vorbis CODEC specification belongs to the public domain. All the technical details are published and documented, and any software entity may make full use of the format without royalty or patent concerns. This package contains: .) libvorbis, a BSD-style license software implementation of the Vorbis specification by the Xiph.Org Foundation (http://www.xiph.org/) .) libvorbisfile, a BSD-style license convenience library built on Vorbis designed to simplify common uses and a number of GPL example programs .) libvorbisenc, a BSD-style license library that provides a simple, programmatic encoding setup interface .) example code making use of libogg, libvorbis, libvorbisfile and libvorbisenc CONTACT: The Ogg homepage is located at 'http://www.xiph.org/ogg/'. Vorbis's homepage is located at 'http://www.xiph.org/ogg/vorbis/'. Up to date technical documents, contact information, source code and pre-built utilities may be found there. BUILDING FROM CVS: ./autogen.sh make and as root if desired: make install This will install the vorbis libraries (static and shared) into /usr/local/lib, includes into /usr/local/include and API manpages (once we write some) into /usr/local/man. BUILDING FROM TARBALL DISTRIBUTIONS: ./configure make and optionally (as root): make install BUILDING RPMS: after normal configuring: make dist rpm -ta libvorbis-.tar.gz BUILDING ON MACOS 9: Vorbis on MacOS 9 is built using CodeWarrior 5.3. To build it, first verify that the Ogg libraries are already built following the instructions in the Ogg module README. Open vorbis/mac/libvorbis.mcp, switch to the "Targets" pane, select everything, and make the project. Do the same thing to build libvorbisenc.mcp, and libvorbisfile.mcp (in that order). In vorbis/mac/Output you will now have both debug and final versions of Vorbis shared libraries to link your projects against. To build a project using Ogg Vorbis, add access paths to your CodeWarrior project for the ogg/include, ogg/mac/Output, vorbis/include, and vorbis/mac/Output folders. Be sure that "interpret DOS and Unix paths" is turned on in your project; it can be found in the "access paths" pane in your project settings. Now simply add the shared libraries you need to your project (OggLib and VorbisLib at least) and #include "ogg/ogg.h" and "vorbis/codec.h" wherever you need to access Ogg and Vorbis functionality.
