| 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 |
| |
| 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. |

| |
| BUILDING FROM TRUNK: |
| |
| Development source is under subversion revision control at |
| https://svn.xiph.org/trunk/vorbis/. 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. |
| |
| [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. |
| |
| Documentation building requires xsltproc and pdfxmltex. |
| |
| BUILDING FROM TARBALL DISTRIBUTIONS: |
| |
| ./configure |
| make |
| |
| and optionally (as root): |
| make install |
| |
| BUILDING RPMS: |
| |
| after normal configuring: |
| |
| make dist |
| rpm -ta libvorbis-<version>.tar.gz |
| |
| BUILDING ON MACOS 9: |
| |
| 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. |
