13Vorbis is a general purpose audio and music encoding format
14contemporary to MPEG-4's AAC and TwinVQ, the next generation beyond
15MPEG audio layer 3. Unlike the MPEG sponsored formats (and other
16proprietary formats such as RealAudio G2 and Windows' flavor of the
17month), the Vorbis CODEC specification belongs to the public domain.
18All the technical details are published and documented, and any
19software entity may make full use of the format without license
20fee, royalty or patent concerns.
21
22This package contains:
23
24* libvorbis, a BSD-style license software implementation of
25 the Vorbis specification by the Xiph.Org Foundation
26 (http://www.xiph.org/)
27
28* libvorbisfile, a BSD-style license convenience library
29 built on Vorbis designed to simplify common uses
30
31* libvorbisenc, a BSD-style license library that provides a simple,
32 programmatic encoding setup interface
33
34* example code making use of libogg, libvorbis, libvorbisfile and
35 libvorbisenc

37WHAT'S HERE:
38
39This source distribution includes libvorbis and an example
40encoder/player to demonstrate use of libvorbis as well as
41documentation on the Ogg Vorbis audio coding format.
42
43You'll need libogg (distributed separately) to compile this library.
44A more comprehensive set of utilities is available in the vorbis-tools
45package.

79BUILDING FROM TRUNK:
80
81Development source is under subversion revision control at
82https://svn.xiph.org/trunk/vorbis/. You will also need the
83newest versions of autoconf, automake, libtool and pkg-config in
84order to compile Vorbis from development source. A configure script
85is provided for you in the source tarball distributions.
86
87 [update or checkout latest source]
88 ./autogen.sh
89 make
90
91and as root if desired:
92
93 make install
94
95This 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.
98
99Documentation building requires xsltproc and pdfxmltex.
100
101BUILDING FROM TARBALL DISTRIBUTIONS:
102
103 ./configure
104 make
105
106and optionally (as root):
107 make install
108
109BUILDING RPMS:
110
111after normal configuring:
112
113 make dist
114 rpm -ta libvorbis-<version>.tar.gz
115
116BUILDING ON MACOS 9:
117
118Vorbis on MacOS 9 is built using Metroworks CodeWarrior. To build it,
119first verify that the Ogg libraries are already built following the
120instructions in the Ogg module README. Open vorbis/mac/libvorbis.mcp,
121switch to the "Targets" pane, select everything, and make the project.
122Do the same thing to build libvorbisenc.mcp, and libvorbisfile.mcp (in
123that order). In vorbis/mac/Output you will now have both debug and final
124versions of Vorbis shared libraries to link your projects against.
125
126To build a project using Ogg Vorbis, add access paths to your
127CodeWarrior project for the ogg/include, ogg/mac/Output,
128vorbis/include, and vorbis/mac/Output folders. Be sure that
129"interpret DOS and Unix paths" is turned on in your project; it can
130be found in the "access paths" pane in your project settings. Now
131simply add the shared libraries you need to your project (OggLib and
132VorbisLib at least) and #include "ogg/ogg.h" and "vorbis/codec.h"
133wherever you need to access Ogg and Vorbis functionality.
