@section intro Introduction
Libburnia is an open-source project for reading, mastering and writing
optical discs.
optical discs. This page is about its capability to handle optical media.
For now this means CD-R, CD-RW, DVD-RAM, DVD+RW, DVD+R, DVD+R/DL, DVD-RW,
DVD-R, BD-RE.
Not supported yet are DVD-R/DL, HD-DVD, BD-R (blue ray). Testers for
DVD-R/DL are wanted, though. BD-R programming efforts would be made
if an interested tester contacts us.
The project comprises of several more or less interdependent parts which
together strive to be a usable foundation for application development.
These are libraries, language bindings, and middleware binaries which emulate
classical (and valuable) Linux tools.
Our scope is currently Linux 2.4 and 2.6 only. For ports to other systems
we would need : login on a development machine resp. a live OS on CD or DVD,
advise from a system person about the equivalent of Linux sg or FreeBSD CAM,
volunteers for testing of realistic use cases.
We have a well tested code base for burning data and audio CDs and many DVD
types. The burn API is quite comprehensively documented and can be used to
build a presentable application.
We have a functional binary which emulates the core use cases of cdrecord in
order to prove that usability, and in order to allow you to explore libburn's
scope by help of existing cdrecord frontends.
ISO 9660 filesystems with Rock Ridge and Joliet extensions can be created
and manipulated quite freely. This capability together with our burn capability
makes possible a single binary application which covers all steps of image
composition, updating and writing. Quite unique in the Linux world.
@subsection components The project components (list subject to growth, hopefully):
- libburn is the library by which preformatted data get onto optical media.
It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
/dev/srM or /dev/hdX (e.g. on kernel 2.6).
libburn is the foundation of our cdrecord emulation. Its code is
independent of cdrecord. Its DVD capabilities are learned from
studying the code of dvd+rw-tools and MMC-5 specs. No code but only
the pure SCSI knowledge has been taken from dvd+rw-tools, though.
- libisofs is the library to pack up hard disk files and directories into a
ISO 9660 disk image. This may then be brought to CD via libburn.
libisofs is to be the foundation of our upcoming mkisofs emulation.
- libisoburn is an add-on to libburn and libisofs which coordinates both and
also allows to grow ISO-9660 filesystem images on multi-session
media as well as on overwriteable media via the same API.
All media peculiarities are handled automatically.
- cdrskin is a limited cdrecord compatibility wrapper for libburn.
cdrecord is a powerful GPL'ed burn program included in Joerg
Schilling's cdrtools. cdrskin strives to be a second source for
the services traditionally provided by cdrecord. Additionally it
provides libburn's DVD/BD capabilities, where only -sao is
compatible with cdrecord.
cdrskin does not contain any bytes copied from cdrecord's sources.
Many bytes have been copied from the message output of cdrecord
runs, though.
See cdrskin/README for more.
- xorriso is an application of all three libraries which creates, loads,
manipulates and writes ISO 9660 filesystem images with
Rock Ridge extensions. Manipulation is not only adding or
overwriting of files but also deletion, renaming, and attribute
changing. An incremental backup feature is provided.
See xorriso/README for more
- "test" is a collection of application gestures and examples given by the
authors of the library features. The burn API example of libburn
is named test/libburner.c . The API for media information inquiry is
demonstrated in test/telltoc.c .
Explore these examples if you look for inspiration.
We strive to be a responsive upstream.
Our libraries are committed to maintain older feature sets in newer versions.
This applies to source code headers (API) as well as to linkable objects (ABI).
The only exception from this rule is about non-release versions x.y.*[13579]
which are allowed to introduce new features, change those new features in
any way and even may revoke such new features before the next release of
x.y.*[02468]. As soon as it is released, a feature is promised to persist.

DVD-R, BD-R, BD-RE.

Our build system is based on autotools.
User experience tells us that you will need at least autotools version 1.7.

Both libraries are written in C language and get built by autotools.
Thus we expect them to be useable by a wide range of Linux-implemented
languages and development tools.
@section libburner Libburner
libburner is a minimal demo application for the library libburn
(see: libburn/libburn.h) as provided on http://libburnia-project.org .
It can list the available devices, can blank a CD-RW or DVD-RW and
can burn to recordable CD and recordable single layer DVD.
It can list the available devices, can burn to recordable CD, DVD, or BD,
can blank a CD-RW or DVD-RW, and can format unformatted DVD-RW, BD-R, or BD-RE.
It's main purpose, nevertheless, is to show you how to use libburn and also
to serve the libburnia team as reference application. libburner does indeed
define the standard way how above three gestures can be implemented and
stay upward compatible for a good while.
