@section intro Introduction
Libburnia is an open-source project for reading, mastering and writing
optical discs. For now this means CD-R, CD-RW, DVD-RAM, DVD+RW, DVD-RW, DVD-R.
Not supported yet are DVD+R, any dual layer media, HD-DVD, BD (blue ray).
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 workable 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.
@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/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.
- 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 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.
- "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 plan to be a responsive upstream. Bear with us.
@section using Using the libraries
Our build system is based on autotools.
User experience tells us that you will need at least autotools version 1.7.
To build libburn and its subprojects it should be sufficient to go into
its toplevel directory and execute
- ./bootstrap (needed if you downloaded from SVN)
- ./configure
- make
To make the libraries accessible for running resp. developing applications
- make install
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 .
It can list the available devices, can blank a CD-RW or DVD-RW and
can burn to CD-R, CD-RW, DVD-RAM, DVD+RW, DVD-RW, DVD-R.
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.
@subsection libburner-help Libburner --help
Usage: test/libburner
[--drive <address>|<driveno>|"-"] [--audio]
[--multi] [<one or more imagefiles>|"-"]
A bus scan (needs rw-permissions to see a drive):
test/libburner --drive -
Burn a file to drive chosen by number, leave appendable:
test/libburner --drive 0 --multi my_image_file
Burn a file to drive chosen by persistent address, close:
test/libburner --drive /dev/hdc my_image_file
Blank a used CD-RW (is combinable with burning in one run):
test/libburner --drive /dev/hdc --blank_fast
Blank a used DVD-RW (is combinable with burning in one run):
test/libburner --drive /dev/hdc --blank_full
Format a DVD-RW to avoid need for blanking before re-use:
test/libburner --drive /dev/hdc --format_overwrite
Burn two audio tracks (to CD only):
lame --decode -t /path/to/track1.mp3
test/dewav /path/to/track2.wav -o
test/libburner --drive /dev/hdc --audio
Burn a compressed afio archive on-the-fly:
( cd my_directory ; find . -print | afio -oZ - ) | \
test/libburner --drive /dev/hdc -
To be read from *not mounted* media via: afio -tvZ /dev/hdc
libburner has two companions, telltoc and dewav, which help to perform some
peripheral tasks of burning.
telltoc prints a table of content (sessions, tracks and leadouts), it tells
about type and state of media, and also is able to provide the necessary
multi-session information for program mkisofs option -C. Especially helpful
are its predictions with "Write multi" and "Write modes" where availability
of "TAO" indicates that tracks of unpredicted length can be written.
See: test/telltoc --help.
dewav extracts raw byte-swapped audio data from files of format .wav (MS WAVE)
or .au (SUN Audio). See example in libburner --help.
