Ralph Giles 33810669d9 Simplify autogen.sh Copy the autogen.sh script from the newer daala project. This just calls autoreconf instead of doing its own tool and version detection. Note that this now means one must explicitly invoke ./configure like in the opus and daala projects. ./autogen.sh will no longer do so.		2015-05-20 10:47:10 -07:00

README.md

Ogg

What's here

This source distribution includes libogg and nothing else. Other modules (eg, the modules libvorbis, vorbis-tools for the Vorbis music codec, libtheora for the Theora video codec) contain the codec libraries for use with Ogg bitstreams.

Directory:

src The source for libogg, a BSD-license inplementation of the public domain Ogg bitstream format
include Library API headers
doc Ogg specification and libogg API documents
win32 Win32 projects and build automation
macosx Mac OS X project and build files

What is Ogg?

Ogg project codecs use the Ogg bitstream format to arrange the raw, compressed bitstream into a more robust, useful form. For example, the Ogg bitstream makes seeking, time stamping and error recovery possible, as well as mixing several sepearate, concurrent media streams into a single physical bitstream.

Contact

The Ogg homepage is located at https://www.xiph.org/ogg/ . Up to date technical documents, contact information, source code and pre-built utilities may be found there.

Building

Building from tarball distributions

./configure
make

and optionally (as root):

make install

This will install the Ogg libraries (static and shared) into /usr/local/lib, includes into /usr/local/include and API documentation into /usr/local/share/doc.

Building from repository source

A standard svn build should consist of nothing more than:

./autogen.sh
make

and as root if desired :

make install

Building on Windows

Use the project file in the win32 directory. It should compile out of the box.

Cross-compiling from Linux to Windows

It is also possible to cross compile from Linux to windows using the MinGW cross tools and even to run the test suite under Wine, the Linux/*nix windows emulator.

On Debian and Ubuntu systems, these cross compiler tools can be installed by doing:

sudo apt-get mingw32 mingw32-binutils mingw32-runtime wine

Once these tools are installed its possible to compile and test by executing the following commands, or something similar depending on your system:

./configure --host=i586-mingw32msvc --target=i586-mingw32msvc --build=i586-linux
make
make check

(Build instructions for Ogg codecs such as vorbis are similar and may be found in those source modules' README files)
