GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
2006 Free Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. Caching is
disabled by default to prevent problems with accidental use of stale
cache files.
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system.
Running `configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug. Until the bug is fixed you can use this workaround:
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

This libburnia.pykix.org toplevel README (C) 2006-2007 Thomas Schmitt
------------------------------------------------------------------------------
Build and Installation
Our build system is based on autotools. For preparing the build of a SVN
snapshot you will need autotools of at least version 1.7.
Check out from SVN by
svn co http://libburnia-svn.pykix.org/libburn/trunk libburn_pykix
go into directory libburn_pykix and apply autotools by
./bootstrap
Alternatively you may unpack a release tarball for which you do not need
autotools installed.
To build a libburnia.pykix.org subproject it should be sufficient to go
into its toplevel directory (here: "libburn_pykix") and execute
./configure
make
To make the libraries accessible for running resp. developing applications
make install
The other half of the project, libisofs, is hosted in the libburnia SVN, too:
svn co http://libburnia-svn.pykix.org/libisofs/trunk libisofs_pykix
See README file there.
------------------------------------------------------------------------------
Overview of libburnia.pykix.org
libburnia.pykix.org is an open-source software project for reading, mastering
and writing optical discs. For now this means only CD-R and CD-RW.
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 do have a workable code base for burning data CDs, though. The burn API is
quite comprehensively documented and can be used to build a presentable
application.
We do have a functional binary which emulates parts of cdrecord in order to
prove that usability, and in order to allow you to explore libburnia's scope
by help of existing cdrecord frontends.
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.
- 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.
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 main API example for libburn
is test/libburner.c .
Explore these examples if you look for inspiration.
We plan to be a responsive upstream. Bear with us. We are still practicing.
------------------------------------------------------------------------------
Project history as far as known to me:
- Founded in 2002 as it seems. See mailing list archives
http://lists.freedesktop.org/archives/libburn/
The site of this founder team is reachable and offers download of a
(somewhat outdated) tarball and from CVS :
http://icculus.org/burn/
Copyright holders and most probably founders:
Derek Foreman and Ben Jansens.
- I came to using libburn in 2005. Founded the cdrskin project and submitted
necessary patches which were accepted or implemented better. Except one
remaining patch which prevented cdrskin from using vanilla libburn from CVS.
The cdrskin project site is reachable and offers download of the heavily
patched (elsewise outdated) tarball under the name cdrskin-0.1.2 :
http://scdbackup.sourceforge.net/cdrskin_eng.html
It has meanwhile moved to use vanilla libburn.pykix.org , though.
Version 0.1.4 constitutes the first release of this kind.
- In Juli 2006 our team mate Mario Danic announced a revival of libburn
which by about nearly everybody else was perceived as unfriendly fork.
Derek Foreman four days later posted a message which expressed his
discontent.
The situation first caused me to publically regret it and then - after i
got the opportunity to move in with cdrskin - gave me true reason to
personally apologize to Derek Foreman, Ben Jansens and the contibutors at
icculus.org/burn. Posted to both projects:
http://lists.freedesktop.org/archives/libburn/2006-August/000446.html
http://mailman-mail1.webfaction.com/pipermail/libburn-hackers/2006-August/000024.html
- Mid August 2006 project cdrskin established a branch office in
libburn.pykix.org so that all maintainers of our tools have one single place
to get the current (at least slightely) usable coordinated versions of
everything.
Project cdrskin will live forth independendly for a while but it is committed
to stay in sync with libburn.pykix.org (or some successor, if ever).
cdrskin is also committed to support icculus.org/burn if the pending fork
is made reality by content changes in that project. It will cease to maintain
a patched version of icculus.org/burn though. Precondition for a new
release of cdrskin on base of icculus.org/burn would be the pending
"whitelist patch" therefore.
I would rather prefer if both projects find consense and merge, or at least
cooperate. I have not given up hope totally, yet.
I, personally, will honor any approach.
- 2nd September 2006 the decision is made to strive for a consolidation of
copyright and a commitment to GPL in a reasonable and open minded way.
This is to avoid long term problems with code of unknown origin and
with finding consense among the not so clearly defined group of copyright
claimers and -holders.
libisofs is already claimed sole copyright Mario Danic.
cdrskin and libburner are already claimed sole copyright Thomas Schmitt.
Rewrites of other components will follow and concluded by claiming full
copyright within the group of libburn.pykix.org-copyright holders.
- 16th September 2006 feature freeze for release of libburn-0.2.2 .
- 20th September 2006 release of libburn-0.2.2 .
- 26th October 2006 feature freeze for cdrskin-0.2.4 based on libburn-0.2.3 .
This version of cdrskin is much more cdrecord compatible in repect
to drive addressing and audio features.
- 30th October 2006 release of cdrskin-0.2.4 .
- 13th November 2006 splitting releases of libburn+cdrskin from libisofs.
- 24th November 2006 release of libburn-0.2.6 and cdrskin-0.2.6 . cdrskin has
become suitable for unaware frontends as long as they perform only the core
of cdrecord use cases (including open-ended input streams, audio, and
multi-session).
- 28th November 2006 the umbrella project which encloses both, libisofs and
libburn, is now called libburnia. For the origin of this name, see
http://en.wikipedia.org/wiki/Liburnians .

Clarification in my name and in the name of Mario Danic, upcoming copyright
holders on toplevel of libburnia. To be fully in effect after the remaining
other copyrighted code has been replaced by ours and by copyright-free
contributions of our friends:
------------------------------------------------------------------------------
We, the copyright holders, agree on the interpretation that
dynamical linking of our libraries constitutes "use of" and
not "derivation from" our work in the sense of GPL, provided
those libraries are compiled from our unaltered code.
Thus you may link our libraries dynamically with applications
which are not under GPL. You may distribute our libraries and
application tools in binary form, if you fulfill the usual
condition of GPL to offer a copy of the source code -altered
or unaltered- under GPL.
We ask you politely to use our work in open source spirit
and with the due reference to the entire open source community.
If there should really arise the case where above clarification
does not suffice to fulfill a clear and neat request in open source
spirit that would otherwise be declined for mere formal reasons,
only in that case we will duely consider to issue a special license
covering only that special case.
It is the open source idea of responsible freedom which will be
decisive and you will have to prove that you exhausted all own
means to qualify for GPL.
For now we are firmly committed to maintain one single license: GPL.

cdrskin. By Thomas Schmitt <scdbackup@gmx.net>
Integrated sub project of libburnia.pykix.org but also published via:
http://scdbackup.sourceforge.net/cdrskin_eng.html
http://scdbackup.sourceforge.net/cdrskin-0.2.7.tar.gz
Copyright (C) 2006-2007 Thomas Schmitt
------------------------------------------------------------------------------
On top of libburn there is implemented cdrskin 0.2.7, a limited cdrecord
compatibility wrapper which allows to use some libburn features from
the command line.
Interested users of cdrecord are invited to participate in the development
of cdrskin. Contact: scdbackup@gmx.net or libburn-hackers@pykix.org .
We will keep copyright narrow but will of course acknowledge valuable
contributions in a due way.
Important :
This software is provided as is. There is no warranty implied and no
protection against possible damages. You use this on your own risk.
Don't blame me or other authors of libburn if anything goes wrong.
I used it on my own risk with :
SuSE 7.2, kernel 2.4.4, ide-scsi emulation, LITE-ON LTR48125S CD burner, 2002
SuSE 9.0, kernel 2.4.21, ide-scsi emulation, LG GSA-4082B CD/DVD burner, 2004
NEC ND-4570A CD/DVD burner, 2006
RIP-14.4, kernel 2.6.14, no ide-scsi, with all above burners
It fails to compile or run on SuSE 6.4 (kernel 2.2.14).
It does not find the IDE CD burner on SuSE 7.2 without ide-scsi.
Other people sucessfully tested cdrskin on several kernel 2.6 based x86 Linux
systems, including 64 bit systems. (Further reports are welcome.)
Compilation, First Glimpse, Installation
Obtain cdrskin-0.2.7.tar.gz, take it to a directory of your choice and do:
tar xzf cdrskin-0.2.7.tar.gz
cd cdrskin-0.2.7
Or obtain a libburnia.pykix.org SVN snapshot,
go into the toplevel directory of the snapshot (e.g. cd libburn_pykix ),
and execute the autotools script ./bootstrap . Use autools version >= 1.7 .
Within that toplevel directory of either cdrskin-0.2.7 or libburn then execute:
./configure
make
(Note: there are next-level directories "libburn" and "cdrskin". Those
would be the wrong ones. Meant is the highest directory of tarball resp.
SVN download. Among others containing files "AUTHORS", "configure",
"Makefile.am", as well as directories "libburn" and "cdrskin".)
This will already produce a cdrskin binary. But it might be necessary to
install libburn in order to use this binary. Installation of libburn is
beyond the scope of cdrskin. For this, see included libburn docs.
In order to surely get a standalone binary, execute
cdrskin/compile_cdrskin.sh
Version identification and help texts available afterwards:
cdrskin/cdrskin -version
cdrskin/cdrskin --help
cdrskin/cdrskin -help
man cdrskin/cdrskin.1
Install (eventually as superuser) cdrskin to a directory where it can be found:
If cdrskin was already installed by a previous version, or by "make install"
in the course of this installation, then find out where:
which cdrskin
Copy your standalone binary to exactly the address which you get as reply
cp cdrskin/cdrskin /usr/bin/cdrskin
Check the version timestamps of the globally installed binary
cdrskin -version
It is not necessary for the standalone cdrskin binary to have libburn
installed, since it incorporates the necessary libburn parts at compile time.
It will not collide with an installed version of libburn either.
But libpthread must be installed on the system and glibc has to match. (See
below for a way to create a statically linked binary.)
To install the man page, you may do: echo $MANPATH and choose one of the
listed directories to copy the man-page under its ./man1 directory. Like:
cp cdrskin/cdrskin.1 /usr/share/man/man1/cdrskin.1
Usage
The user of cdrskin needs rw-permission for the CD burner device.
A list of rw-accessible drives can be obtained by
cdrskin --devices
CD devices which offer no rw-permission are invisible to normal users.
The superuser should be able to see any usable drive and then set the
permissions as needed. If this hangs then there is a drive with
unexpected problems (locked, busy, broken, whatever). You might have to
guess the address of your (non-broken) burner by other means, then.
On Linux 2.4 this would be some /dev/sgN and on 2.6. some /dev/hdX.
The output of cdrskin --devices might look like
0 dev='/dev/sg0' rwrwr- : '_NEC' 'DVD_RW ND-4570A'
1 dev='/dev/sg1' rwrw-- : 'HL-DT-ST' 'DVDRAM GSA-4082B'
So full and insecure enabling of both for everybody would look like
chmod a+rw /dev/sg0 /dev/sg1
I strongly discourage to run cdrskin with setuid root or via sudo !
It is not checked for the necessary degree of hacker safety.
Usage examples
Get an overview of cdrecord style addresses of available devices
cdrskin -scanbus
cdrskin dev=ATA -scanbus
cdrskin --devices
Adresses reported with dev=ATA need prefix "ATA:". Address examples:
dev=0,1,0 dev=ATA:1,0,0 dev=/dev/sg1 dev=/dev/hdc
See also "Drive Addressing" below.
Obtain some info about the drive
cdrskin dev=0,1,0 -checkdrive
Obtain some info about the drive and the inserted media
cdrskin dev=0,1,0 -atip -v
Thoroughly blank a CD-RW
cdrskin -v dev=0,1,0 blank=all -eject
Blank CD-RW sufficiently for making it ready for overwrite
cdrskin -v dev=0,1,0 blank=fast -eject
Burn image file my_image.iso to CD or DVD+-RW
cdrskin -v dev=0,1,0 speed=12 fs=8m driveropts=burnfree padsize=300k \
-eject my_image.iso
Burn a compressed afio archive to CD or DVD+-RW on-the-fly
find . | afio -oZ - | cdrskin -v dev=0,1,0 fs=32m speed=8 -tao \
driveropts=burnfree padsize=300k -
Burn 6 audio tracks from files with different formats to CD.
Anything except .wav or .au files has to be converted into raw format first.
See below "Audio CD" for specifications.
ogg123 -d raw -f track01.cd /path/to/track1.ogg
oggdec -R -o track02.cd /path/to/track2.ogg
lame --decode -t /path/to/track3.mp3 track03.cd
madplay -o raw:track04.cd /path/to/track4.mp3
mppdec --raw-le /path/to/track5.mpc track05.cd
cdrskin -v dev=0,1,0 blank=fast -eject speed=48 -sao \
-audio -swab track0[1-5].cd /path/to/track6.wav
Usage example with http://scdbackup.sourceforge.net
Address may be a cdrecord-style "scsibus,target,lun" as listed with
cdrskin -scanbus (and hopefully as listed with cdrecord -scanbus) :
export SCDBACKUP_SCSI_ADR="0,1,0"
or a device file address as listed by --devices with an accessible drive :
export SCDBACKUP_SCSI_ADR="/dev/sg1"
Set usage of cdrskin with appropriate options rather than cdrecord :
export SCDBACKUP_CDRECORD="cdrskin -v -v"
Run a backup :
scdbackup_home
Restrictions
The major restrictions are lifted now: audio, TAO, multi-session do work.
Many cdrecord options are still unsupported, though.
If you have use cases for them, please report your wishes and expectations.
DVD support is still immature and restricted to DVD+-RW for now.
Inspiration and Standard
For the original meaning of cdrecord options see :
man cdrecord
(http://cdrecord.berlios.de/old/private/man/cdrecord-2.0.html)
Do not bother Joerg Schilling with any cdrskin problems.
(Be cursed if you install cdrskin as "cdrecord" without clearly forwarding
this "don't bother Joerg" demand.)
cdrskin does not contain any bytes copied from cdrecord's sources. Many bytes
have been copied from the message output of cdrecord runs, though. I am
thankful to Joerg Schilling for every single one of them.
Actually i, Thomas Schmitt, am a devoted user of cdrecord via my project
scdbackup which still runs a bit better with cdrecord than with cdrskin. TAO.
I have the hope that Joerg feels more flattered than annoyed by cdrskin.
Drive Addressing
Drives get addressed either via their cdrecord-style addresses as listed
with option -scanbus (see below "Pseudo-SCSI Adresses") or via the paths
of device files.
Not only device files listed by --devices may be used but also device files
which via their major,minor numbers point to the same device driver as
a listed device file.
Helpful with Linux kernel 2.4 is a special SCSI feature:
It is possible to address a scsi(-emulated) drive via associated device files
which are not listed by option --devices but point to the same SCSI addresses
as listed device files. This addressing via e.g. /dev/sr0 or /dev/scd1 is
compatible with generic read programs like dd and with write program growisofs.
Pseudo-SCSI Adresses
cdrecord and cdrskin share the syntax of SCSI addresses but not necessarily
the meaning of the components. A cdrecord-style address for cdrskin
[prefix:]scsibus,target,lun
can be interpreted in two different modes.
Standard mode tries to be compatible to original cdrecord. This should be true
with (emulated) SCSI where the /dev/sgN with is looked up with matching
scsibus,target,lun as given by the operating system.
With dev=ATA: or dev=ATAPI: the translation to /dev/hdX is purely literal
but matches the cdrecord addresses on all systems tested so far:
X = 'a' + 2 * scsibus + target
where target only may have the values 0 or 1.
In this mode, option -scanbus will list only SCSI devices unless option
dev=ATA or dev=ATAPI are given, which will suppress SCSI devices and only
show IDE drives (i.e. /dev/hdX without ide-scsi emulation).
In mode --old_pseudo_scsi_adr there is a scsibus,target,lun representation
which has nothing to do with SCSI and thus is not compatible to cdrecord.
Each number triple corresponds either to a device file address or to a
libburn drive number.
Component "scsibus" indicates the translation method. Defined busses are:
0 target is the libburn drivenumber as listed with --devices
1 associated to device file /dev/sgN , target chooses N
2 associated to device file /dev/hdX , target 0='a', 1='b' ..., 25='z'
So "1,1,0" is /dev/sg1, "2,3,0" is /dev/hdd, "0,2,0" is libburn drive #2 at
some unspecified device file.
This scheme shall help to keep cdrecord-style addresses stable and exchangeable
between users without excluding drives with unexpected device addresses.
The numbering on bus 0 is prone to arbitrary changes caused by changes in
drive accessability.
Further busses may emerge as libburn evolves. "prefix" and "lun" may get
a meaning. To stay upward compatible, use addresses as printed by -scanbus.
User Defined Device Address Translation
Some programs or users have their own ideas about the address of their burner.
K3b 0.10 for example derives cdrecord addresses by own examination of the
devices and not by calling cdrecord -scanbus.
Standard mode will hopefully be fully compatible with their ideas.
Old frontends which do not know dev=ATA or dev=ATAPI and which do ask their
"cdrecord" via -scanbus may be well served with option --old_pseudo_scsi_adr .
To direct any remaining stubborn callers to the appropriate drives, cdrskin
allows to define device address aliases. Like
cdrskin dev_translation=+1,0,0+/dev/sg1 \
dev_translation=+ATA:1,0,0+/dev/sg1 \
dev_translation=-"cd+dvd"-0,1,0 \
...
Any of the addresses dev=1,0,0, dev=ATA:1,0,0, dev=cd+dvd will be mapped to
/dev/sg1 resp. to 0,1,0.
The first character after "dev_translation=" defines the character which
separates the two parts of the translation pair. (Above: "+" and "-".)
In K3b 0.10 it is possible to employ alternative writer programs by setting
their full path (e.g. /usr/bin/cdrskin) in menu
Settings:Configure K3b...:Programs:Search Path
and to make them default in menu
Settings:Configure K3b...:Programs:Programs:
A suitable setting for "cdrecord" in menu
Settings:Configure K3b...:Programs:User Parameters
would then probably be
-v dev_translation=+1,0,0+/dev/sg1
You will learn from button "Show Debugging Output" after a failed burn run
what cdrecord command was used with what address "dev=...". This address "..."
will be the right one to replace "1,0,0" in above example.
Startup Files
If not --no_rc is the first argument then cdrskin attempts on startup to read
arguments from the following three files:
/etc/default/cdrskin
/etc/opt/cdrskin/rc
/etc/cdrskin/cdrskin.conf
$HOME/.cdrskinrc
The files are read in the sequence given above.
Each readable line is treated as one single argument. No extra blanks.
A first character '#' marks a comment, empty lines are ignored.
Example content of a startup file:
# This is the default device
dev=0,1,0
# To accomodate to eventual remnant cdrskin-0.2.2 addresses
dev_translation=+1,0,0+0,1,0
# Some more options
fifo_start_at=0
fs=16m
Audio CD
Lorenzo Taylor enabled option -audio in cdrskin (thanks !) and reports neat
results with audio data files which are :
headerless PCM (i.e. uncompressed)
44100 Hz sampling rate
16 bits per sample
stereo (2 channels)
little-endian byte order with option -swab, or big-endian without -swab
Files with name extension .wav get examined wether they are in Microsoft WAVE
format with above parameters and eventually get extracted by cdrskin itself.
In the same way files with name extension .au get examined wether they are
in SUN's audio format. For both formats, track format -audio and eventual
endianness option -swab are enabled automatically.
Any other formats are to be converted to format .wav with above parameters
or to be extracted as raw CD track data by commands like those given above
under "Usage examples". Those raw files need option -audio and in most cases
option -swab to mark them as little-endian/Intel/LSB-first 16-bit data.
Incorrect endianness setting results in random noise on CD.
I myself am not into audio. So libburn-hackers@pykix.org might be the
best address for suggestions, requests and bug reports.
DVD+RW and DVD-RAM
DVD+RW and DVD-RAM media get treated as blank media regardless wether they
hold data or not. Options -audio and -multi are not allowed. Only one track
is allowed. -toc does not return information about the media content.
Speed is counted in DVD units (i.e. 1x = 1,385,000 bytes/second). Currently
there is no difference between -sao and -tao. If ever, then -tao will be the
mode which preserves the current behavior.
For these media, -msinfo alone would not be enough to perform appending of an
ISO filesystem. The filesystem driver will need a hint to find the start of the
most recent session. For example put an ISO filesystem at address 1 GB:
mkisofs -C 0,524288 ... | \
cdrskin dev=/dev/sr0 -v fs=32m -eject speed=4 write_start_address=524288s -
The superuser may then do:
mount -t iso9660 -o ro,sbsector=524288 /dev/sr0 /mnt
Note: On my linux-2.4.21-215 mount works only with sbsector <= 337920 (660 MB).
To extend a filesystem already existing at address 0
mkisofs -C 0,524288 -M /dev/sr0 ... | cdrskin dev=/dev/sr0 ...
Record the number 524288 for usage as first number with -C at the next
extension:
mkisofs -C 524288,1000000 ... | cdrskin write_start_address=1000000s ...
Program growisofs can append to an ISO filesystem on DVD+RW by additionally
manipulating the first session. cdrskin does not want to get involved so deep
into the format of the burned data. Be advised to use growisofs for the
task of maintaining extendable ISO-Filesystems on DVD+RW.
DVD-RW
DVD-RW are usable if formatted to state "Restricted Overwrite". They then
behave much like DVD+RW. See above.
DVD-RW in state "Sequential" have first to be formatted by
cdrskin dev=... -v blank=format_overwrite
"Sequential" is the state of unused media and of media previously blanked
or written by cdrecord. dvd+rw-format -blank can also achieve this state.
(Command dvd+rw-format -force can achieve "Restricted Overwrite".)
Formatting or first use of freshly formatted DVD-RW can produce unusual noises
from the drive and last several minutes. Depending on mutual compatibility of
drive and media, formatting can yield unusable media. It seems that those die
too on blanking by cdrecord or dvd+rw-format. Perils of DVD-RW, i fear.
There are three formatting variants with cdrskin currently:
blank=format_overwrite uses "DVD-RW Quick" formatting (MMC-type 15h)
and writes a first session of 128 MB. This leads to media which are expandable
and random addressable by cdrskin.
blank=format_overwrite_quickest uses "DVD-RW Quick" formatting (type 15h) too,
but leaves the media in "intermediate" state. In the first session of writing
one may only write sequentially to such a DVD. After that, it gets random
addressable by cdrskin.
blank=format_overwrite_full uses preferrably "Full Format" (type 00h).
This formatting lasts as long as writing a full DVD. It includes writing of
lead-out which is said to be good for DVD ROM compatibility.
Special compilation variations
You may get a (super fat) statically linked binary by :
cdrskin/compile_cdrskin.sh -static
if your system supports static linking, at all. This will not help with kernels
which do not properly support the necessary low-level interfaces chosen by
your compile-time libraries.
A size reduced but fully functional binary may be produced by
cdrskin/compile_cdrskin.sh -do_strip
An extra lean binary with reduced capabilities is created by
cdrskin/compile_cdrskin.sh -do_diet -do_strip
It will not read startup files, will abort on option dev_translation= ,
will not have a fifo buffer, and will not be able to put out help texts or
debugging messages.

cdrskin is currently copyright Thomas Schmitt only.
It adopts the following commitment by the toplevel copyright holders:
------------------------------------------------------------------------------
We, the copyright holders, agree on the interpretation that
dynamical linking of our libraries constitutes "use of" and
not "derivation from" our work in the sense of GPL, provided
those libraries are compiled from our unaltered code.
Thus you may link our libraries dynamically with applications
which are not under GPL. You may distribute our libraries and
application tools in binary form, if you fulfill the usual
condition of GPL to offer a copy of the source code -altered
or unaltered- under GPL.
We ask you politely to use our work in open source spirit
and with the due reference to the entire open source community.
If there should really arise the case where above clarification
does not suffice to fulfill a clear and neat request in open source
spirit that would otherwise be declined for mere formal reasons,
only in that case we will duely consider to issue a special license
covering only that special case.
It is the open source idea of responsible freedom which will be
decisive and you will have to prove that you exhausted all own
means to qualify for GPL.
For now we are firmly committed to maintain one single license: GPL.

.SH NAME
cdrskin \- burns preformatted data to CD-R, CD-RW, DVD+/-RW, DVD-RAM
via libburn.
.SH SYNOPSIS
.B cdrskin
.RI [ options | track_source_addresses ]
.br
.SH DESCRIPTION
.PP
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
.\" respectively.
.PP
\fBcdrskin\fP is a program that provides some of cdrecord's options
in a compatible way for CD media. With DVD it has its own ways for now.
You do not need to be superuser for its daily usage.
.PP
.B Overview of features:
.br
Blanking of CD-RW.
.br
Burning of data or audio tracks to CD,
.br
either in versatile Track at Once mode (TAO)
.br
or in Session at Once mode for seamless tracks.
.br
Multi session on CD (follow-up sessions in TAO only).
.br
Bus scan, burnfree, speed options, retrieving media info, padding, fifo.
.br
Burning of a single data track to DVD+RW, DVD-RW or DVD-RAM.
.br
See section EXAMPLES at the end of this text.
.PP
.B Track recording model:
.br
The input-output entities which get processed are called tracks.
A \fBtrack\fP stores a stream of bytes.
.br
Each track is initiated by one track source address argument, which may either
be "-" for standard input or the address of a readable file. If no write mode
is given explicitely then one will be chosen which matches the peculiarities
of track sources and the state of the output media.
.PP
More than one track can be burned by a single run of cdrskin.
In the terms of the MMC standard all tracks written by the same run constitute
a \fBsession\fP.
.br
CDs can be kept appendable so that further tracks can
be written to them in subsequent runs of cdrskin (see option -multi).
Info about the addresses of burned tracks is kept in a table of
content (TOC) on media and can be retrieved via cdrskin option -toc.
These informations are also used by the operating systems' CD-ROM read drivers.
.PP
In general there are two types of tracks: data and audio. They differ in
sector size, throughput and readability via the systems' CD-ROM drivers
resp. by music CD players.
.br
If not explicitely option -audio is given, then any track is burned as type
data, unless the track source is a file with suffix ".wav" or ".au" and has a
header part which identifies it as MS-WAVE resp. SUN Audio with suitable
parameters. Such files are burned as audio tracks by default.
.PP
While audio tracks just contain a given time span of acoustic vibrations,
data tracks may have an arbitray meaning. Nevertheless, ISO-9660 filesystems
are established as a format which can represent a tree of directories and
files on all major operating systems. Such filesystem images can be
produced by programs mkisofs or genisoimage. They can also be extended by
follow-up tracks if prepared properly. See the man pages of said programs.
cdrskin is able to fulfill the needs about their option -C.
.br
Another type of data track content are archive formats which originally
have been developed for magnetic tapes. Only formats which mark a detectable
end-of-archive in their data are suitable, though. Well tested are
the archivers afio and star. Not suitable seems GNU tar.
.PP
.B Recordable CD Media:
.br
CD-R can be initially written only once and eventually extended until they
get closed (or are spoiled because they are overly full). After that they are
read-only.
.br
CD-RW media can be blanked to make them re-usable for another
round of overwriting. Usually
.B blank=fast
is the appropriate option.
Blanking damages the previous content but does not
make it completely unreadable. It is no effective privacy precaution.
Multiple cycles of blanking and overwriting with random numbers might be.
.PP
.B Recordable DVD Media:
.br
Currently only types DVD+RW, DVD-RW and DVD-RAM can be burned via cdrskin.
.br
DVD+RW and DVD-RAM media get treated as blank media regardless wether they
hold data or not. They need no special initial formatting.
Options -audio and -multi are not allowed. Only one track is allowed.
-toc does not return information about the media content.
Speed is counted in DVD units (i.e. 1x = 1,385,000 bytes/second). Currently
there is no difference between -sao and -tao. If ever, then -tao will be the
mode which preserves the current behavior.
.br
DVD-RW need to be formatted to state "Restricted Overwrite". Then they behave
much like DVD+RW. This formatting can be done by option
.B blank=format_overwrite
It is necessary for unused media, for media written or blanked by cdrecord,
for media which have been written unformatted by growisofs or blanked by
dvd+rw-format -blank. If in doubt, just give it a try.
.PP
.B Drive preparation and addressing:
.br
The drives, either CD burners or DVD burners, are accessed via addresses which
are specific to libburn and the operating system. Those addresses get listed
by a run of \fBcdrskin --devices\fP.
.br
On Linux, they are device files which traditionally do not offer
w-permissions for normal users. Because libburn needs rw-permission,
it might be only the superuser who is able to get this list without further
precautions.
.br
It is consensus that \fBchmod a+rw /dev/sg0\fP or \fBchmod a+rw /dev/hdc\fP
is less security sensitive than chmod u+s /usr/bin/cdrskin. The risk for the
drive is somewhat higher but the overall system is much less at stake.
.br
.PP
If you only got one CD capable drive then you may leave out cdrskin option
\fBdev=\fP. Else you should use this option to address the drive you want.
.br
cdrskin option dev= not only accepts the listed addresses but also
traditional cdrecord SCSI addresses which on Linux consist of three
numbers: Bus,Target,Lun. There is also a related address family "ATA" which
accesses IDE drives not under control of Linux SCSI drivers:
ATA:Bus,Target,Lun.
.br
See option -scanbus for getting a list of cdrecord style addresses.
.br
Further are accepted on Linux: links to libburn-suitable device files,
device files which have the same major and minor device number,
and device files which have the same SCSI address parameters (e.g. /dev/sr0).
.br
.SH OPTIONS
.TP
.BI \-\-help
Show non-cdrecord compatible options.
.TP
.BI \-help
Show cdrecord compatible options.
.TP
.BI \-version
Print cdrskin id line, compatibility lure line, libburn version, cdrskin
version, version timestamp, build timestamp (if available), and then exit.
.PP
Alphabetical list of options which are intended to be compatible with
original cdrecord by Joerg Schilling:
.TP
.BI \-atip
Retrieve some info about media state. With CD-RW print "Is erasable".
With DVD media print "book type:" and a media type text.
.TP
.BI \-audio
Announces that the subsequent tracks are to be burned as audio.
The source is supposed to be uncompressed headerless PCM, 44100 Hz, 16 bit,
stereo. For little-endian byte order (which is usual on PCs) use option
-swab. Unless marked explicitely by option -data, input files with suffix
.wav are examined wether they have a header in MS-WAVE format confirming
those parameters and eventually raw audio data get extracted and burned as
audio track. Same is done for suffix .au and SUN Audio.
.TP
.BI blank= type
Blank a CD-RW or format a DVD+/-RW.
This is combinable with burning in the same run of cdrskin.
The type given with blank= selects the particular behavior:
.RS
.TP
help
Print this list of blanking types.
.TP
all
Blank an entire CD.
.TP
fast
Minimally blank an entire CD.
.TP
format_overwrite
Format a DVD-RW to "Restricted Overwrite". The user should bring some patience.
(Note: format_overwrite* are not original cdrecord options.)
.TP
format_overwrite_quickest
Like format_overwrite without creating a 128 MB trailblazer session.
Leads to "intermediate" state which only allows sequential write
beginning from address 0.
The "intermediate" state ends after the first session of writing data.
.TP
format_overwrite_full
For DVD-RW this is like format_overwrite but claims full media size
rather than just 128 MB.
Most traditional formatting is attempted. No data get written.
Much patience is required.
.br
For DVD+RW this is the only supported explicit formatting type. It provides
complete "de-icing" so no reader slips on unwritten data areas.
.RE
.TP
.BI \-checkdrive
Retrieve some info about the addressed drive.
Exits with non-zero value if the drive cannot be found and opened.
.TP
.BI \-dao
Alias for option -sao. Write disk in Session at Once mode.
.TP
.BI \-data
Subsequent tracks are data tracks. This option is default and only needed
to mark the end of the range of an eventual option -audio.
.TP
.BI dev= target
Set the address of the drive to use. Valid are at least the
addresses listed with option --devices,
X,Y,Z addresses listed with option -scanbus,
ATA:X,Y,Z addresses listed with options dev=ATA -scanbus,
and volatile libburn drive numbers (numbering starts at "0").
Other device file addresses which lead to the same drive might work too.
.br
If no dev= is given, volatile address "dev=0" is assumed. That is the first
drive found being available. Better avoid this ambiguity on systems with more
than one drive.
.br
The special target "help" lists hints about available addressing formats.
Be aware that deprecated option --old_pseudo_scsi_adr may change the meaning
of Bus,Target,Lun addresses.
.TP
.BI driveropts= opt
Set "driveropts=burnfree" to enable the drive's eventual protection mechanism
against temporary lack of source data (i.e. buffer underrun).
It is not an error to do this with a drive that has no such capabilities.
.TP
.BI \-dummy
Try to perform the drive operations without actually affecting the inserted
media. There is no guarantee that this will work with a particular drive
in a particular write mode. Blanking is prevented reliably, though.
.TP
.BI \-eject
Eject the disk after work is done.
.TP
.BI \-force
Assume that the user knows better in situations when cdrskin or libburn are
insecure about drive or media state. This includes the attempt to blank
media which are classified as unknown or unsuitable, and the attempt to use
write modes which libburn believes they are not supported by the drive.
.br
Another application is with blank=format_* to enforce re-formatting of media
which appear to be sufficiently formatted already.
.br
Use this only when in urgent need.
.TP
.BI fs= size
Set the fifo size to the given value. The value may have appended letters which
multiply the preceding number:
.br
"k" or "K" = 1024 , "m" or "M" = 1024k , "g" or "G" = 1024m , "s" or "S" = 2048
.br
Set size to 0 in order to disable the fifo (default is "4m").
.br
The fifo buffers an eventual temporary surplus of track source data in order to
provide the drive with a steady stream during times of temporary lack of track
source supply.
The larger the fifo, the longer periods of poor source supply can be
compensated.
But a large fifo needs substantial time to fill up if not curbed via
option fifo_start_at=size.
.TP
.BI gracetime= seconds
Set the grace time before starting to write. (Default is 0)
.TP
.BI msifile= path
Run option -msinfo and copy the result line into the file given by path.
Unlike -msinfo this option does not redirect all normal output away from
standard output. But it may be combined with -msinfo to achieve this.
.br
Note: msifile=path is actually an option of wodim and not of cdrecord.
.TP
.BI \-msinfo
Retrieve multi-session info for preparing a follow-up session by option -C
of programs mkisofs or genisoimage. Print result to standard output.
This option redirects to stderr all
message output besides its own result string, which consists of two numbers.
The result string shall be used as argument of option -C with said programs.
It gives the start address of the most recent session and the predicted
start address of the next session to be appended. The string is empty if
the most recent session was not written with option -multi.
.TP
.BI \-multi
This option keeps the CD appendable after the current session has been written.
Without it the disk gets closed and may not be written any more - unless it
is a CD-RW and gets blanked which causes loss of its content.
.br
The following sessions can only be written in -tao mode.
.br
In order to have all filesystem content accessible, the eventual ISO-9660
filesystem of a follow-up
session needs to be prepared in a special way by the filesystem formatter
program. mkisofs and genisoimage expect particular info about the situation
which can be retrieved by cdrskin option -msinfo.
.br
To retrieve an archive file which was written as follow-up session,
you may use option -toc to learn about the "lba" of the desired track number.
.TP
.BI \-nopad
Do not add trailing zeros to the data stream. Nevertheless, since there seems
to be no use for audio tracks with incomplete last sector, this option applies
only to data tracks. There it is default.
.TP
.BI \-pad
Add 30 kB of trailing zeros to each data track. (This is not sufficient to
avoid problems with various CD-ROM read drivers.)
.TP
.BI padsize= size
Add the given amount of trailing zeros to the next data track. This option
gets reset to padsize=0 after that next track is written. It may be set
again before the next track argument. About size specifiers, see option fs=.
.TP
.BI \-raw96r
Write disk in RAW/RAW96R mode. This mode allows to put more payload bytes
into a CD sector but obviously at the cost of error correction. It can only
be used for tracks of fixely predicted size. Some drives allow this mode but
then behave strange or even go bad for the next few attempts to burn a CD.
One should use it only if inavoidable.
.TP
.BI \-sao
Write disk in Session At Once mode. This mode is able to put several audio
tracks on CD without producing audible gaps between them. It can only
be used for tracks of fixely predicted size. This implies that track arguments
which depict stdin or named pipes need to be preceeded by option tsize= or
by option tao_to_sao_tsize=.
.TP
.BI \-scanbus
Scan the system for drives. On Linux the drives at /dev/s* and at /dev/hd*
are to be scanned by two separate runs. One without dev= for /dev/s* and
one with dev=ATA for /dev/hd* devices. (Option --drives lists all available
drives in a single run.)
.br
Drives which are busy or which offer no rw-permission to the user of cdrskin
are not listed. Busy drives get reported in form of warning messages.
.br
The useful fields in a result line are:
.br
Bus,Target,Lun Number) 'Vendor' 'Mode' 'Revision'
.TP
.BI speed= number
Set speed of drive. With data CD, 1x speed corresponds to a throughput of
150 kB/s. It is not an error to set a speed higher than is suitable for drive
and media. One should stay within a realistic speed range, though.
.TP
.BI \-swab
Announce that the raw audio data source of subsequent tracks is byte swapped
versus the expectations of cdrecord. This option is suitable for audio where
the least significant byte of a 16 bit word is first (little-endian, Intel).
Most raw audio data on PC systems are available in this byte order.
Less guesswork is needed if track sources are in format MS-WAVE in a file with
suffix ".wav".
.TP
.BI \-tao
Write disk in Track At Once (TAO) mode. This mode can be used with track
sources of unpredictable size, like standard input or named pipes. It is
also the only mode that can be used for writing to appendable CD which
already hold data.
.TP
.BI \-toc
Print the table of content (TOC) which describes the tracks recorded on CD.
The output contains all info from option -atip plus lines which begin with
"track:", the track number, the word "lba:" and a number which gives the
start address of the track. Addresses are counted in CD sectors which with
SAO or TAO data tracks hold 2048 bytes each.
.RS
.TP
Example. Retrieve an afio archive from track number 2:
.br
tracknumber=2
.br
lba=$(cdrskin dev=/dev/cdrom -toc 2>&1 | \\
.br
grep '^track:[ ]*[ 0-9][0-9]' | \\
.br
tail +"$tracknumber" | head -1 | \\
.br
awk '{ print $4}' )
.br
dd if=/dev/cdrom bs=2048 skip="$lba" | \\
.br
afio -t - | less
.RE
.TP
.BI tsize= size
Announces the exact size of the next track source. This is necessary with any
write mode other than -tao if the track source is not a regular disk file, but
e.g. "-" (standard input) or a named pipe.
About size specifiers, see option fs=.
.br
If the track source does not deliver the predicted amount of bytes, the
remainder of the track is padded with zeros. This is not considered an error.
If on the other hand the track source delivers more than the announced bytes
then the track on CD gets truncated to the predicted size and cdrskin exits
with non-zero value.
.TP
.BI \-v
Increment verbose level by one. Startlevel is 0 with only few messages.
Level 1 prints progress report with long running operations and also causes
some extra lines to be put out with info retrieval options.
Level 2 additionally reports about option settings derived from arguments or
startup files. Level 3 is for debugging and useful mainly in conjunction with
somebody who had a look into the program sourcecode.
.PP
Alphabetical list of options which are genuine to cdrskin and intended for
normal use:
.TP
.BI \--allow_setuid
Disable the loud warning about insecure discrepance between login user and
effective user which indicates application of chmod u+s to the program binary.
One should not do this chmod u+s , but it is an old cdrecord tradition.
.TP
.BI \--any_track
Allow source_addresses to begin with "-" (plus further characters) or to
contain a "=" character.
By default such arguments are seen as misspelled options. It is nevertheless
not possible to use one of the options listed with --list_ignored_options.
.TP
.BI \--demand_a_drive
Exit with a nonzero value if no drive can be found during a bus scan.
.TP
.BI \--devices
List the device file addresses of all accessible CD drives. In order to get
listed, a drive has to offer rw-permission for the cdrskin user and it may
not be busy. The superuser should be able to see all idle drives listed and
busy drives reported as "SORRY" messages.
.br
Each available drive gets listed by a line containing the following fields:
.br
Number dev='Devicefile' rw-Permissions : 'Vendor' 'Model'
.br
Number and Devicefile can both be used with option dev=, but number is
volatile (numbering changes if drives become busy).
.TP
.BI fifo_start_at= size
Do not wait for full fifo but start burning as soon as the given number
of bytes is read. This option may be helpful to bring the average throughput
near to the maximum throughput of a drive. A large fs= and a small
fifo_start_at= combine a quick burn start and a large savings buffer to
compensate for temporary lack of source data. At the beginning of burning,
the software protection against buffer underun is as weak as the size of
fifo_start_at= . So it is best if the drive offers hardware protection which
has to be enabled by driveropts=burnfree.
.TP
.BI \--list_ignored_options
List all ignored cdrecord options. The --options cannot be used as addresses
of track sources. No track source address may begin with a text equal to an
option which ends by "=". The list is ended by an empty line.
.TP
.BI \--no_rc
Only if used as first command line argument this option prevents reading and
interpretation of eventual startup files. See section FILES below.
.TP
.BI \--single_track
Accept only the last argument of the command line as track source address.
.TP
.BI write_start_address= byte_offset
Set the address on media where to start writing the track. With DVD+RW or
DVD-RAM byte_offset must be aligned to 2 KB blocks, but better is 32 kB.
With DVD-RW 32 kB alignment is mandatory.
.br
Other media are not suitable for this option yet.
.PP
Alphabetical list of options which are only intended for very special
situations and not for normal use:
.TP
.BI \--abort_handler
Establish default signal handling not to leave a drive in busy state
but rather to shut it down and to wait until it has ended the final operations.
This option is only needed for revoking eventual --ignore_signals or
--no_abort_handler.
.TP
.BI dev_translation= <sep><from><sep><to>
Set drive address alias. This was necessary before cdrskin-0.2.4 to manually
translate cdrecord addresses into cdrskin addresses.
.br
<sep> is a single character which may not occur in the address string
<from>. <from> is an address as expected to be given by the user via option
dev=. <to> is the address to be used instead whenever <from> is given.
More than one translation instruction can be given in one cdrskin run.
.br
E.g.: dev_translation=+ATA:1,0,0+/dev/sg1 dev_translation=+ATA:1,1,0+/dev/sg2
.TP
.BI \--drive_abort_on_busy
Linux specific: Abort process if a busy drive is encountered.
.TP
.BI \--drive_blocking
Linux specific: Try to wait for a busy drive to become free.
This is not guaranteed to work with all drivers. Some need nonblocking i/o.
.TP
.BI \--drive_not_exclusive
Linux specific: Do not ask the operating system to prevent opening busy drives.
Wether this leads to senseful behavior depends on operating system and kernel.
.TP
.BI \--drive_scsi_exclusive
Linux specific:
Try to exclusively reserve device files /dev/srN, /dev/scdM, /dev/stK of drive.
this would be helpful to protect against collisions with program growisofs.
Regrettably on Linux kernel 2.4 with ide-scsi emulation this seems not to
work. Wether it becomes helpful with new Linux systems has to be evaluated.
.TP
.BI \--fifo_disable
Disable fifo despite any fs=.
.TP
.BI \--fifo_per_track
Use a separate fifo for each track.
.TP
.BI grab_drive_and_wait= seconds
Open the addressed drive, wait the given number of seconds, release the drive,
and do normal work as indicated by the other options used. This option helps
to explore the program behavior when faced with busy drives. Just start a
second cdrskin with option --devices while grab_drive_and_wait= is still
active.
.TP
.BI \--ignore_signals
Try to ignore any signals rather than to abort the program. This is not a
very good idea. You might end up waiting a very long time for cdrskin
to finish.
.TP
.BI \--no_abort_handler
On signals exit even if the drive is in busy state. This is not a very good
idea. You might end up with a stuck drive that refuses to hand out the media.
.TP
.BI \--no_blank_appendable
Refuse to blank appendable CD-RW. This is a feature that was once builtin with
libburn. No information available for what use case it was needed.
.TP
.BI \--no_convert_fs_adr
Do only literal translations of dev=. This prevents cdrskin from test-opening
device files in order to find one that matches the given dev= specifier.
.br
Partly Linux specific:
Such opening is needed for Bus,Target,Lun addresses unless option
--old_pseudo_scsi_adr is given. It is also needed to resolve device file
addresses which are not listed with cdrskin --devices but nevertheless point
to a usable drive. (Like /dev/sr0 using the same SCSI address as /dev/sg0.)
.TP
.BI \--old_pseudo_scsi_adr
Linux specific:
Use and report literal Bus,Target,Lun addresses rather than real SCSI and
pseudo ATA addresses. This method is outdated and was never compatible with
original cdrecord.
.TP
.BI tao_to_sao_tsize= size
Set an exact fixed size for the next track to be in effect only if the track
source cannot deliver a size prediction and no tsize= was specified.
This is the fallback from bad old times when cdrskin was unable to burn
in mode -tao.

<DT>The goal is to provide some of cdrecord's options in a compatible way.
This has been achieved quite sufficiently for the needs of backup tool
<A HREF="http://scdbackup.sourceforge.net/main_eng.html">scdbackup</A>
and for data CD projects of <A HREF="http://www.k3b.org">K3b</A>
(see <A HREF="#examples">examples</A>).
Suitability for audio CD frontends has been improved much and is now being
evaluated.<BR>
Further enhancements depend on people who can describe and discuss their
wishes as well as on the development of libburn.</DT>

<LI>
cdrskin -scanbus or --devices hangs for quite a while if there is
a CD drive which does not work properly (e.g. because it has individual
problems with DMA).
So if the superuser gets no result with cdrskin --devices then one should
disable DMA with the problematic CD drives
(like: <KBD>hdparm -d0 /dev/hdd</KBD> )
and try again.<BR>
In severe cases it might be necessary to guess the device name /dev/sgN resp.
/dev/hdX of the non-ill burner if it cannot be found otherwise among its
ill peers. Alternatively one can guess the address of the ill device, remove
rw-permissions and retry the bus scan as non-superuser.

Enhancements towards previous stable version cdrskin-0.2.4:
<UL>
<LI>Option <KBD><B>-tao</B></KBD> is fully enabled.<BR>
SAO is still the preferred default but TAO is default if a track of
unpredicted size is present (stdin, named pipe, ...) or if a follow-up
session is written to an appendable CD.
(This is an intentional deviation from cdrecord defaults which themselves
have changed with the newest cdrecord versions.)
</LI>
<LI>Status report during blank, preparation and finalization improved.</LI>
<LI>Bug fixed: Trailing trash appended to .wav files caused error message
and, if exceeding fifo size, could even stall a burn.
(Workaround: disable fifo by <KBD><B>fs=0</B></KBD>)</LI>
<LI>Bug fixed: False speed with first pacifier cycle. Potential program
abort by floating point exception (NaN).</LI>
<LI>multi-session CDs: <KBD><B>-multi</B></KBD>, <KBD><B>-msinfo</B></KBD>,

<CENTER><H3>About the relationship of cdrecord and cdrskin</H3></CENTER>
First of all: this relationship is single sided, as cdrskin has to be aware of
cdrecord but not vice versa.
<BR>
<BR>
I am a long time user of cdrecord and it works fine for me.
Especially i do appreciate its write mode -tao which allows to pipe arbitrary
data on CD and CD-RW via stdin. cdrecord is reliable, versatile and well
maintained. So for me - there would be not problem with it.
<BR>
But the author of cdrecord and the Linux kernel people foster a very hostile
relationship. Ok, that's their business, not mine (or ours if you are with me).
One has to be aware, though, that this relationship might lead to a situation
where cdrecord is no longer available for certain Linux kernels.
<BR>
To have my own project prepared for such a time, i began to implement its
cdrecord gestures on top of libburn.
From now on i invite other interested users of cdrecord to teach cdrskin
the gestures necessary for their cdrecord applications.
Contact me. Let's see what we can achieve.
<BR>
<BR>
libburn and cdrskin are now mature enough to substitute cdrecord in its
major use cases of CD burning. It is possible to foist cdrskin on various
software packages if it gets falsely named "cdrecord".
I do not encourage this approach, but of course such a replacement
opportunity is the goal of a cdrecord compatibility wrapper.
<BR>
<BR>
It is very important to me that this project is not perceived as hostile
towards Joerg Schilling and his ongoing work.
I owe him much. For cdrecord, for mkisofs, for star. Chapeau.
<BR>

[[Image(source:/libburn/trunk/cdrskin/doener_150x200_tr.gif)]] [http://en.wikipedia.org/wiki/D%C3%B6ner_kebab Doener]
'''cdrskin is the cdrecord compatibility middleware of libburn.'''
Its paragon, 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. Currently it does CD-R and CD-RW.
Its future ability to burn DVD media depends on the development of libburn.
cdrskin does not contain any bytes copied from cdrecord's sources.
Many bytes have been copied from the message output of cdrecord
runs, though. The most comprehensive technical overview of cdrskin
can be found in [http://libburnia.pykix.org/browser/libburn/trunk/cdrskin/README?format=txt cdrskin/README].
About libburn API for burning CD: http://libburnia-api.pykix.org
--------------------------------------------------------------------------
Appending sessions to an unclosed CD is restricted to write mode TAO.
(Users who have a burner which succeeds with a follow-up session via
cdrecord -sao : please contact us.)
The development version of cdrskin is able to burn a single track to DVD+RW
or DVD-RW media.
For other DVD types and for appending sessions to ISO filesystems see the
advise to use dvd+rw-tools at the end of this text.
--------------------------------------------------------------------------
About the command line options of cdrskin:
They are described in detail in [http://scdbackup.sourceforge.net/man_1_cdrskin_devel.html#OPTIONS section OPTIONS] of
[http://scdbackup.sourceforge.net/man_1_cdrskin_devel.html man cdrskin]
There are two families of options: cdrecord-compatible ones and options
which are specific to cdrskin. The latter are mostly used to configure
cdrskin for its task to emulate cdrecord. There are some, nevertheless,
which provide rather exotic unique features of cdrskin.
The cdrecord-compatible options are listed in the output of
{{{
cdrskin -help
}}}
where the option "help" has *one* dash. Online: [http://scdbackup.sourceforge.net/cdrskin_help_devel cdrskin -help]
For these options you may expect program behavior that is roughly the
same as described in original man cdrecord .
Online: http://cdrecord.berlios.de/old/private/man/cdrecord-2.0.html
The cdrskin-specific options are listed by
{{{
cdrskin --help
}}}
where the option "help" has *two* dashes. Online: [http://scdbackup.sourceforge.net/cdrskin__help_devel cdrskin --help]
Some are very experimental and should only be
used in coordination with the libburnia developer team.
Some are of general user interest, though:
--------------------------------------------------------------------------
--devices allows the sysadmin to scan the system for possible drives
and displays their detected properties.
The drives are listed one per line, with fields:
libburn-drive-number, sysadmin-device-file, permissions, vendor, type
{{{
0 dev='/dev/sg0' rwrw-- : 'HL-DT-ST' 'DVDRAM GSA-4082B'
}}}
This feature is valuable since cdrskin -scanbus will not give you
the device file name and its current permissions.
cdrskin will accept of course the proposed dev= option as address
for any usage of the drive.
Different from cdrecord, cdrskin is intended to be run without special
privileges, i.e. no superuser setuid. It is intended that the sysadmin
controls drive accessability by rw-permissions of the drive rather than
by x-permission of the burn binary. To be usable with cdrskin, the drive
has to offer both, r- and w-permission.
--------------------------------------------------------------------------
Non-cdrecord blank mode blank=format_overwrite is needed to bring a DVD-RW
disc from its initial profile "Sequential Recording" into profile state
"Restricted Overwrite". The latter is usable with cdrskin.
{{{
cdrskin dev=/dev/sr0 -v blank=format_overwrite
}}}
DVD-RW "Restricted Overwrite" and DVD+RW appear to cdrskin as blank media
which are capable of taking only a single track. This track may be positioned
on a 32KiB aligned address, though.
{{{
cdrskin ... write_start_address=2412m ...
}}}
--------------------------------------------------------------------------
fifo_start_at=<num> is a throughput enhancer for unsteady data streams
like they are produced by a compressing archiver program when piping to
CD on-the-fly. It makes better use of the general property of a FIFO
buffer to transport surplus bandwidth into the future. Yep. A time machine.
One-way, i fear.
FIFO originally was introduced by cdrecord's author Joerg Schilling in order
to protect mediocre burner hardware from suffering buffer underruns
and thus producing misburns (at 1x speed on CD-R media at the price of a
DVD-RAM nowadays). This purpose would not justify a fifo any more -
given the limited life time of burners and the seamless underrun protection
of contemporary consumer drives.
With an unsteady data stream the task of the buffer is to soak up peak
performance and to release it steadily at the drive's maximum speed.
The larger the buffer the more reserves can be built up and the longer
input drought can be compensated.
Original cdrecord has the historical property, though, to first wait until
the buffer is completely filled. Best practice for fighting drive
underruns, of course.
With a very fat fs=# buffer (128 MB for 12x CD is not unrealistic) this
can cause a big delay until burning finally starts and takes its due time.
fifo_start_at=<num> makes cdrskin start burning after the given number of bytes
is read rather than waiting for the FIFO to be completely full resp. the data
stream to end. It risks a few drive buffer underruns at the beginning of burn
- but modern drives stand this.
Usage examples:
{{{
cdrskin ... fs=128m fifo_start_at=20m ...
cdrskin ... fifo_start_at=0 ...
}}}
Note: no FIFO can give you better average throughput than the average
throughput of the data source and the throughput of the burner.
It can be used, though, to bring the effective throughput very close
to the theoretical limit. Especially with high speed media.
--------------------------------------------------------------------------
--no_rc allows you to surely ban influence from systemwide or user specific
default settings of cdrskin. Possible locations for such settings:
/etc/default/cdrskin
/etc/opt/cdrskin/rc
/etc/cdrskin/cdrskin.conf
$HOME/.cdrskinrc
--------------------------------------------------------------------------
tao_to_sao_tsize=<num> allows the - actually unsupported - cdrecord option
-tao and defines a default track size to be used if - as custom with -tao -
no option tsize=# is given.
Since -tao is supported in cdrskin-0.2.6 the TAO-to-SAO workaround has become
quite obsolete. Nevertheless, tao_to_sao_tsize= allows to preset a default
size for SAO mode which is in effect only if no track size is available.
As in general with cdrskin tsize=# the data source does not have to provide
the full annouced amount of data. Missing data will be padded up by 0-bytes.
Surplus data is supposed to cause an error, though. The burn will then
be a failure in any way.
--------------------------------------------------------------------------
dev_translation=<sep><from><sep><to> may be needed to foist cdrskin to
frontend programs of cdrecord which do *not* ask cdrecord -scanbus but
which make own assumptions and guesses about cdrecord's device addresses.
Normally, cdrskin understands all addresses which are suitable for cdrecord
under Linux. See cdrskin/README, "Pseudo-SCSI Adresses".
This option is mainly for (yet unknown) exotic configurations or very
stubborn frontend programs.
If a frontend refuses to work with cdrskin, look into the error protocol
of that frontend, look at the output of a run of cdrskin --devices and give
cdrskin the necessary hint.
Example: Your frontend insists in using "0,0,0" and --devices reported
dev='/dev/hdc' resp. cdrskin dev=ATA -scanbus reported "1,0,0" then this
would be the appropriate translation:
{{{
dev_translation=+0,0,0+/dev/hdc
}}}
The "+" character is a separator to be choosen by you.
Currently i am not aware of the need to choose any other than "+"
unless you get playful with custom translations like
{{{
dev_translation=-"cd+dvd"-1,0,0
}}}
See http://scdbackup.sourceforge.net/k3b_on_cdrskin.html
for an illustrated example with K3b 0.10 .
--------------------------------------------------------------------------
DVD advise:
For burning of DVD media the cdrskin project currently advises to use
Andy Polyakov's dvd+rw-tools which despite their historic name burn
for me on above burner: DVD+RW, DVD+R, DVD-RW, DVD-R .
http://fy.chalmers.se/~appro/linux/DVD+RW/tools
They are not compatible or related to cdrecord resp. cdrecord-ProDVD
(now obsoleted by original source cdrtools cdrecord with identical
capabilities besides the license key).
libburn and thus the cdrskin project are currently aquiring own capabilities
to burn to DVD media. For now restricted to DVD+RW and DVD-RW and to single
tracks.
To my knowledge, Linux kernels 2.6 do write to DVD+RW via block devices as
they would write to a traditional tape device. Try old tape archiver
commands with addresses like /dev/sr0 or /dev/hdc rather than /dev/mt0 .
I have heard rumors that DVD-RW in mode "restricted overwrite" would be
block device ready, too. My burner is not a real friend of DVD-RW and
in an experiment the burn worked fine - but the result was not identical
to the stream sent to the device. I had similar failure with DVD-RAM, too.
Beware of the impact of a slow block device on overall system i/o buffering.
It is wise to curb its input to a speed which it is able to deliver to media.
Else your i/o dedicated RAM might buffer a big amount of stream data.

/**
@author Mario Danic, Thomas Schmitt
@mainpage Libburnia Documentation Index
@section intro Introduction
Libburnia is an open-source project for reading, mastering and writing
optical discs. For now this means only CD-R and CD-RW.
Support for DVD+RW and DVD-RW is emerging.
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. 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.
- 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.
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 main API example of libburn
is named test/libburner.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 http://libburn.pykix.org .
It can list the available devices, can blank a CD-RW and
can burn to CD-R or CD-RW.
New: burning to DVD+/-RW (single data track, single session only).
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
<pre>
Usage: test/libburner
[--drive <address>|<driveno>|"-"] [--audio]
[--blank_fast|--blank_full] [--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
Burn two audio tracks
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* CD via: afio -tvZ /dev/hdc
Program tar would need a clean EOF which our padded CD cannot deliver.
</pre>
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 CD media, and also is able to provide the necessary
multi-session information for program mkisofs option -C.
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.

/*
This is the main operating system dependent SCSI part of libburn. It implements
the transport level aspects of SCSI control and command i/o.
Present implementation: FreeBSD CAM (untested)
PORTING:
Porting libburn typically will consist of adding a new operating system case
to the following switcher files:
os.h Operating system specific libburn definitions and declarations.
sg.c Operating system dependent transport level modules.
and of deriving the following system specific files from existing examples:
os-*.h Included by os.h. You will need some general system knowledge
about signals and knowledge about the storage object needs of your
transport level module sg-*.c.
sg-*.c This source module. You will need special system knowledge about
how to detect all potentially available drives, how to open them,
eventually how to exclusively reserve them, how to perform
SCSI transactions, how to inquire the (pseudo-)SCSI driver.
You will not need to care about CD burning, MMC or other high-level
SCSI aspects.
Said sg-*.c operations are defined by a public function interface, which has
to be implemented in a way that provides libburn with the desired services:
sg_give_next_adr() iterates over the set of potentially useful drive
address strings.
scsi_enumerate_drives() brings all available, not-whitelist-banned, and
accessible drives into libburn's list of drives.
sg_drive_is_open() tells wether libburn has the given drive in use.
sg_grab() opens the drive for SCSI commands and ensures
undisturbed access.
sg_release() closes a drive opened by sg_grab()
sg_issue_command() sends a SCSI command to the drive, receives reply,
and evaluates wether the command succeeded or shall
be retried or finally failed.
sg_obtain_scsi_adr() tries to obtain SCSI address parameters.
Porting hints are marked by the text "PORTING:".

/** Overview
libburner is a minimal demo application for the library libburn as provided
on http://libburnia.pykix.org . It can list the available devices, can
blank a CD-RW, can format a DVD-RW, and can burn to CD-R, CD-RW, DVD+RW,
DVD-RAM or DVD-RW.
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()

to prefer because it only touches one drive. On modern Linux kernels,
there should be no fatal disturbance of ongoing burns of other libburn
instances with any of our approaches. We use open(O_EXCL) by default.

above by burn_drive_get_adr(). By such an address one may use
burn_drive_scan_and_grab() to finally aquire exactly one drive.

In both cases you have to be aware that the desired drive might get

/* License and copyright aspects:
This all is provided under GPL.
Read. Try. Think. Play. Write yourself some code. Be free of my copyright.
Be also invited to study the code of cdrskin/cdrskin.c et al.
Clarification in my name and in the name of Mario Danic, copyright holder
on toplevel of libburnia. To be fully in effect after the remaining other
copyrighted code has been replaced by ours and by copyright-free contributions
of our friends:
We, the copyright holders, agree on the interpretation that
dynamical linking of our libraries constitutes "use of" and
not "derivation from" our work in the sense of GPL, provided
those libraries are compiled from our unaltered code.
Thus you may link our libraries dynamically with applications
which are not under GPL. You may distribute our libraries and
application tools in binary form, if you fulfill the usual
condition of GPL to offer a copy of the source code -altered
or unaltered- under GPL.
We ask you politely to use our work in open source spirit
and with the due reference to the entire open source community.
If there should really arise the case where above clarification
does not suffice to fulfill a clear and neat request in open source
spirit that would otherwise be declined for mere formal reasons,
only in that case we will duely consider to issue a special license
covering only that special case.
It is the open source idea of responsible freedom which will be
decisive and you will have to prove that you exhausted all own
means to qualify for GPL.
For now we are firmly committed to maintain one single license: GPL.
History:
libburner is a compilation of my own contributions to test/burniso.c and
fresh code which replaced the remaining parts under copyright of
Derek Foreman.
My respect and my thanks to Derek for providing me a start back in 2005.
