-
- 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
- http://svn.xiph.org/trunk/vorbis/. You will also need the
- newest versions of autoconf, automake, and libtool 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.
-
- 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.
