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 + (https://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 + +## What's here ## + +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. + +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 + +- `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. + +## Contact ## + +The Ogg homepage is located at 'https://www.xiph.org/ogg/'. +Vorbis's homepage is located at 'https://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/ + +## Building ## + +#### Building from master #### + +Development source is under git revision control at +https://git.xiph.org/vorbis.git. You will also need the +newest versions of autoconf, automake, libtool and pkg-config in +order to compile Vorbis from development source. A configure script +is provided for you in the source tarball distributions. + + ./autogen.sh + ./configure + 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. + +Documentation building requires xsltproc and pdfxmltex. + +#### Building from tarball distributions #### + + ./configure + make + +and optionally (as root): + + make install + +#### Building RPM packages #### + +after normal configuring: + + make dist + rpm -ta libvorbis-<version>.tar.gz + +## Building with CMake ## + +Ogg supports building using [CMake](http://www.cmake.org/). CMake is a meta build system that generates native projects for each platform. +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): + + cmake -G YOUR-PROJECT-GENERATOR . + +Note that by default cmake generates projects that will build static libraries. +To generate projects that will build dynamic library use `BUILD_SHARED_LIBS` option like this: + + cmake -G YOUR-PROJECT-GENERATOR -DBUILD_SHARED_LIBS=1 . + +After projects are generated use them as usual + +#### Building on Windows #### + +Use proper generator for your Visual Studio version like: + + cmake -G "Visual Studio 12 2013" . + +#### Building on Mac OS X #### + +Use Xcode generator. To build framework run: + + cmake -G Xcode -DBUILD_FRAMEWORK=1 . + +#### Building on Linux #### + +Use Makefile generator which is default one. + + cmake . + make + +## License ## + +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'.
