THIS FILE IS PART OF THE OggVorbis SOFTWARE CODEC SOURCE CODE. USE, DISTRIBUTION AND REPRODUCTION OF THIS LIBRARY SOURCE IS GOVERNED BY A BSD-STYLE SOURCE LICENSE INCLUDED WITH THIS SOURCE IN 'COPYING'. PLEASE READ THESE TERMS BEFORE DISTRIBUTING.

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 license fee, 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
• libvorbisenc, a BSD-style license library that provides a simple, programmatic encoding setup interface
• example code making use of libogg, libvorbis, libvorbisfile and libvorbisenc

This source distribution includes libvorbis and an example encoder/player to demonstrate use of libvorbis as well as documentation on the Ogg Vorbis audio coding format. 

You'll need libogg (distributed separately) to compile this library. A more comprehensive set of utilities is available in the vorbis-tools package.

Vorbis's homepage is located at http://www.xiph.org/vorbis/ . 

Up to date technical documents, contact information, source code and pre-built utilities may be found there. 

The user website for Ogg Vorbis software and audio is http://vorbis.com/ . 

Development source is under subversion revision control at http://svn.xiph.org/trunk/vorbis/ . 

You will also need the newest versions of autoconf, automake, and libtool in order to compile vorbis from development source. A configure script is provided for you in the source tarball distributions. 

[update or checkout latest source] ./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. 

./configure make 

and optionally (as root): make install 

after normal configuring: 

make dist

rpm -ta libvorbis-<version>.tar.gz

Vorbis on MacOS 9 is built using Metroworks CodeWarrior. 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.
