13 Vorbis is a general purpose audio and music encoding format
14 contemporary to MPEG-4's AAC and TwinVQ, the next generation beyond
15 MPEG audio layer 3. Unlike the MPEG sponsored formats (and other
16 proprietary formats such as RealAudio G2 and Windows' flavor of the
17 month), the Vorbis CODEC specification belongs to the public domain.
18 All the technical details are published and documented, and any
19 software entity may make full use of the format without license
20 fee, royalty or patent concerns.
22 This package contains:
24 * libvorbis, a BSD-style license software implementation of
25 the Vorbis specification by the Xiph.Org Foundation
26 (http://www.xiph.org/)
28 * libvorbisfile, a BSD-style license convenience library
29 built on Vorbis designed to simplify common uses
31 * libvorbisenc, a BSD-style license library that provides a simple,
32 programmatic encoding setup interface
34 * example code making use of libogg, libvorbis, libvorbisfile and
39 This source distribution includes libvorbis and an example
40 encoder/player to demonstrate use of libvorbis as well as
41 documentation on the Ogg Vorbis audio coding format.
43 You'll need libogg (distributed separately) to compile this library.

77 The user website for Ogg Vorbis software and audio is http://vorbis.com/
81 Development source is under subversion revision control at
82 http://svn.xiph.org/trunk/vorbis/. You will also need the
83 newest versions of autoconf, automake, and libtool in order
84 to compile vorbis from development source. A configure script
85 is provided for you in the source tarball distributions.
87 [update or checkout latest source]
91 and as root if desired:
95 This will install the vorbis libraries (static and shared) into
96 /usr/local/lib, includes into /usr/local/include and API manpages
97 (once we write some) into /usr/local/man.
99 BUILDING FROM TARBALL DISTRIBUTIONS:
104 and optionally (as root):
109 after normal configuring:
112 rpm -ta libvorbis-<version>.tar.gz
116 Vorbis on MacOS 9 is built using Metroworks CodeWarrior. To build it,
117 first verify that the Ogg libraries are already built following the
118 instructions in the Ogg module README. Open vorbis/mac/libvorbis.mcp,
119 switch to the "Targets" pane, select everything, and make the project.
120 Do the same thing to build libvorbisenc.mcp, and libvorbisfile.mcp (in
121 that order). In vorbis/mac/Output you will now have both debug and final
122 versions of Vorbis shared libraries to link your projects against.
124 To build a project using Ogg Vorbis, add access paths to your
125 CodeWarrior project for the ogg/include, ogg/mac/Output,
126 vorbis/include, and vorbis/mac/Output folders. Be sure that
127 "interpret DOS and Unix paths" is turned on in your project; it can
128 be found in the "access paths" pane in your project settings. Now
129 simply add the shared libraries you need to your project (OggLib and
130 VorbisLib at least) and #include "ogg/ogg.h" and "vorbis/codec.h"
131 wherever you need to access Ogg and Vorbis functionality.
