7 Vorbis is a general purpose audio and music encoding format
8 contemporary to MPEG-4's AAC and TwinVQ, the next generation beyond
9 MPEG audio layer 3. Unlike the MPEG sponsored formats (and other
10 proprietary formats such as RealAudio G2 and Windows' flavor of the
11 month), the Vorbis CODEC specification belongs to the public domain.
12 All the technical details are published and documented, and any
13 software entity may make full use of the format without license
14 fee, royalty or patent concerns.
16 This package contains:
18 - libvorbis, a BSD-style license software implementation of
19 the Vorbis specification by the Xiph.Org Foundation
20 (https://www.xiph.org/)
22 - libvorbisfile, a BSD-style license convenience library
23 built on Vorbis designed to simplify common uses
25 - libvorbisenc, a BSD-style license library that provides a simple,
26 programmatic encoding setup interface
28 - example code making use of libogg, libvorbis, libvorbisfile and
33 This source distribution includes libvorbis and an example
34 encoder/player to demonstrate use of libvorbis as well as
35 documentation on the Ogg Vorbis audio coding format.
37 You'll need libogg (distributed separately) to compile this library.
38 A more comprehensive set of utilities is available in the vorbis-tools
43 - `lib` The source for the libraries, a BSD-license implementation of the public domain Ogg Vorbis audio encoding format.
45 - `include` Library API headers
47 - `debian` Rules/spec files for building Debian .deb packages
49 - `doc` Vorbis documentation
51 - `examples` Example code illustrating programmatic use of libvorbis, libvorbisfile and libvorbisenc
53 - `macosx` Project files for MacOS X.
55 - `win32` Win32 projects files and build automation
57 - `vq` Internal utilities for training/building new LSP/residue and auxiliary codebooks.

70 #### Building from master ####
72 Development source is under git revision control at
73 https://git.xiph.org/vorbis.git. You will also need the
74 newest versions of autoconf, automake, libtool and pkg-config in
75 order to compile Vorbis from development source. A configure script
76 is provided for you in the source tarball distributions.
82 and as root if desired:
86 This will install the Vorbis libraries (static and shared) into
87 /usr/local/lib, includes into /usr/local/include and API manpages
88 (once we write some) into /usr/local/man.
90 Documentation building requires xsltproc and pdfxmltex.
92 #### Building from tarball distributions ####
97 and optionally (as root):
101 #### Building RPM packages ####
103 after normal configuring:
106 rpm -ta libvorbis-<version>.tar.gz
108 ## Building with CMake ##
110 Ogg supports building using [CMake](http://www.cmake.org/). CMake is a meta build system that generates native projects for each platform.
111 To generate projects just run cmake replacing `YOUR-PROJECT-GENERATOR` with a proper generator from a list [here](http://www.cmake.org/cmake/help/v3.2/manual/cmake-generators.7.html):
113 cmake -G YOUR-PROJECT-GENERATOR .
115 Note that by default cmake generates projects that will build static libraries.
116 To generate projects that will build dynamic library use `BUILD_SHARED_LIBS` option like this:
118 cmake -G YOUR-PROJECT-GENERATOR -DBUILD_SHARED_LIBS=1 .
120 After projects are generated use them as usual
122 #### Building on Windows ####
124 Use proper generator for your Visual Studio version like:
126 cmake -G "Visual Studio 12 2013" .
128 #### Building on Mac OS X ####
130 Use Xcode generator. To build framework run:
132 cmake -G Xcode -DBUILD_FRAMEWORK=1 .
134 #### Building on Linux ####
136 Use Makefile generator which is default one.
