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.

------------------------------------------------------------------------------
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://libburn-svn.pykix.org/trunk libburn_pykix
and apply autotools by
./bootstrap
Alternatively you may unpack a release tarball for which you do not need
autotools installed.
To build libburn.pykix.org and its subprojects 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
------------------------------------------------------------------------------
Overview of libburn.pykix.org
libburn.pykix.org is an open-source library 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 and we will have a hard time to widen
this for now, because of our history. The project could need advise from or
membership of skilled kernel people and people who know how to talk CD/DVD
drives into doing things.
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 libburn'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

Clarification in my name and in the name of Mario Danic, upcoming copyright
holders on toplevel of libburn. 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 libburn.pykix.org but also published via:
http://scdbackup.sourceforge.net/cdrskin_eng.html
http://scdbackup.sourceforge.net/cdrskin-0.2.4.tar.gz
Copyright (C) 2006 Thomas Schmitt
------------------------------------------------------------------------------
On top of libburn there is implemented cdrskin 0.2.4, 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-0.2.4.tar.gz , take it to a directory of your choice and do:
tar xzf cdrskin-0.2.4.tar.gz
cd cdrskin-0.2.4
Or obtain a libburn.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-0.2.4 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 an help texts available afterwards:
cdrskin/cdrskin -version
cdrskin/cdrskin --help
cdrskin/cdrskin -help
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.)
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
Note: Adresses reported with dev=ATA are to be used with prefix "ATA:". You may
well use device file addresses as reported with --devices. Examples:
dev=0,1,0 dev=/dev/sg1 dev=ATA:1,0,0 dev=/dev/hdc
See also "Drive Addressing".
Note: Address numbers have changed since cdrskin-0.2.2 in order to become
compatible with cdrecord numbers. To get the old number scheme, use
option --old_pseudo_scsi_adr . See also "Pseudo-SCSI Adresses".
Sorry for any inconvenience.
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
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
cdrskin -v dev=0,1,0 speed=12 fs=8m -sao driveropts=burnfree padsize=300k \
-eject my_image.iso
Burn a compressed afio archive to CD on-the-fly
find . | afio -oZ - | cdrskin -v dev=0,1,0 fs=32m speed=8 -sao \
driveropts=burnfree padsize=300k tsize=650m -
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 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 tao_to_sao_tsize=650m"
Run a backup :
scdbackup_home
Restrictions
The convenient burn mode TAO is not available with libburn yet.
Therefore it has to be defaulted to mode SAO which needs to know the track
size in advance. non-cdrecord option tao_to_sao_tsize=650m causes each CD
to get burned up to 650 MB regardless of the payload size.
No multi session yet ... Please report your wishes.
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/defaults/cdrskin
/etc/opt/cdrskin/rc
$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_empty
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.
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.
