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.
