NEW AND IMPORTANT:
If you're used to the source distribution from the first two beta
releases, things are now rearranged a bit. Specifically, the
'vorbis' CVS module contains only the libvorbis, libvorbisfile, and
libvorbisenc libraries. Because Ogg bitstreams are to be used by other
Ogg codecs, Ogg framing and streaming functionality is now in libogg
(the 'ogg' CVS module). Vorbis utilities are in 'vorbis-tools' and various
player plugins are in 'vorbis-plugins'. For now, you'll need to check
out these other modules seperately. (Note: the xmms plugin is in the xmms
CVS tree in xmms/Input/vorbis.)
Secondly, the Ogg/Vorbis build systems now use automake. Instead of
'./configure; make', the proper build sequence (in each module) is
'./autogen.sh; make'.
You will also need the newest versions of autoconf, automake, and libtool
in order to compile vorbis from CVS. configure scripts are provided for you
in tarball distributions.
WHAT'S HERE:
This source distribution includes libvorbis and an example
encoder/player to demonstrate use of libvorbis and documentation on
the Ogg Vorbis audio coding format.
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
./mac Codewarrior project files and build tweaks for MacOS.
./win32 Win32 projects files and build automation
./vq Internal utilities for training/building new LSP/residue
and auxiliary codebooks.
WHAT IS VORBIS:
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 royalty or
patent concerns.
This package contains:
.) libvorbis, a BSD-license software implementation of
the Vorbis specification by the Xiphophorus company
(http://www.xiph.org/)
.) libvorbisfile, a BSD-license convenience library
built on Vorbis designed to simplify common uses and a number of GPL
example programs
.) libvorbisenc, a BSD-license library that provides a simple, programmatic
encoding setup interface
.) example code making use of libogg, libvorbis, libvorbisfile and
libvorbisenc
CONTACT:
The Ogg homepage is located at 'http://www.xiph.org/ogg/'.
Vorbis's homepage is located at 'http://www.xiph.org/ogg/vorbis/'.
Up to date technical documents, contact information, source code and
pre-built utilities may be found there.
BUILDING FROM CVS:
./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 CodeWarrior 5.3. 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.
