Not supported yet are dual layer media, HD-DVD, BD (blue ray). Testers for dual layer DVD+/-R are wanted, though.
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.
We plan to be a responsive upstream. Bear with us.
To build libburn and its subprojects it should be sufficient to go into its toplevel directory and execute
To make the libraries accessible for running resp. developing applications
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.
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.
Usage: test/libburner
[--drive <address>|<driveno>|"-"] [--audio]
[--blank_fast|--blank_full|--format_overwrite]
[--try_to_simulate]
[--multi] [<one or="" more="" imagefiles>="">|"-"]
Examples
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 track1.cd
test/dewav /path/to/track2.wav -o track2.cd
test/libburner --drive /dev/hdc --audio track1.cd track2.cd
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.

It can list the available devices, can blank a CD-RW or DVD-RW, can format a DVD-RW, can burn to CD-R, CD-RW, DVD-R, DVD+R, DVD+RW, DVD-RAM or DVD-RW. Not supported yet: double layer media. It's main purpose, nevertheless, is to show you how to use libburn and also to serve the libburnia team as reference application. libburner.c does indeed define the standard way how above three gestures can be implemented and stay upward compatible for a good while. Before you can do anything, you have to initialize libburn by burn_initialize() and provide some signal and abort handling, e.g. by the builtin handler, by burn_set_signal_handling() as it is done in main() at the end of this file. Then you aquire a drive in an appropriate way conforming to the API. The two main approaches are shown here in application functions: libburner_aquire_by_adr() demonstrates usage as of cdrecord traditions libburner_aquire_by_driveno() demonstrates a scan-and-choose approach With that aquired drive you can blank a CD-RW libburner_blank_disc() or you can format a DVD-RW to profile "Restricted Overwrite" (needed once) libburner_format_row() With the aquired drive you can burn to CD-R, CD-RW, DVD+RW, DVD-RAM, DVD-RW libburner_payload() When everything is done, main() releases the drive and shuts down libburn: burn_drive_release(); burn_finish() */ /** See this for the decisive API specs . libburn.h is The Original */ /* For using the installed header file : #include <libburn/libburn.h> */ /* This program insists in the own headerfile. */ #include "../libburn/libburn.h" /* libburn is intended for Linux systems with kernel 2.4 or 2.6 for now */ #include <stdio.h> #include <ctype.h> #include <sys/types.h> #include <unistd.h> #include <string.h> #include <stdlib.h> #include <time.h> #include <errno.h> #include <sys/stat.h> #include <fcntl.h> /** For simplicity i use global variables to represent the drives.
