added libraries: opus flac libsndfile updated: libvorbis libogg openal - Everything works as expected for now. Bare in mind libsndfile needed the check for whether or not it could find the xiph libraries removed in order for this to work.

# 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 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://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 ##
|
|
|
|
#### Building from master ####
|
|
|
|
Development source is under git revision control at
|
|
https://gitlab.xiph.org/xiph/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](https://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](https://cmake.org/cmake/help/latest/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
|
|
|
