cdrskin

Limited cdrecord compatibility wrapper for libburn

Purpose:

Burns preformatted data to CD and DVD media:
CD-R, DVD-R, DVD+R, DVD+R/DL, CD-RW, DVD-RW, DVD-RAM, DVD+RW

Hardware requirements:

A CD/DVD recorder suitable for http://libburnia-project.org
(SCSI , ATA , USB , or SATA writers compliant to standard MMC-3 for CD and to MMC-5 for DVD).

Software requirements :

Linux with kernel 2.4 or higher (and libc, of course) :: With kernel 2.4 an ATA drive has to be under ide-scsi emulation.; With kernel 2.6 the drive should not be under ide-scsi.
libpthread: is supposed to be a standard system component.

GPL software included:

libburn-0.4.4: (founded by Derek Foreman and Ben Jansens, furthered by team of libburnia-project.org); transfers data to CD and DVD

This program system has been tested on Intel/AMD Linux systems only.
Ports to other usable systems are appreciated. Reports are welcome.

Special features:

Source code is independent of cdrecord

Commands:

The most common options of cdrecord for data and audio on CD media are provided in a compatible way. On single layer DVD media cdrskin is able to perform any recording job which is possible with cdrecord. Other than with cdrecord, options -multi and -tao are supported with certain DVD types.
Get an overview of drives and their addresses: # cdrskin -scanbus; # cdrskin dev=ATA -scanbus; # cdrskin --devices
Being superuser avoids permission problems with /dev/srN resp. /dev/hdX .
Ordinary users should then get granted rw access to the /dev files as listed by option --devices.

Get info about a particular drive or loaded media:: $ cdrskin dev=0,1,0 -checkdrive; $ cdrskin dev=ATA:1,0,0 -v -atip; $ cdrskin dev=/dev/hdc -toc
Make used CD-RW or used unformatted DVD-RW writable again:: $ cdrskin -v dev=/dev/sg1 blank=fast -eject; $ cdrskin -v dev=/dev/dvd blank=all -eject
Format DVD-RW to avoid need for blanking before re-use:: $ cdrskin -v dev=/dev/sr0 blank=format_overwrite
De-format DVD-RW to make it capable of multi-session again:: $ cdrskin -v dev=/dev/sr0 blank=deformat_sequential
Write ISO-9660 filesystem image as only one to blank or formatted media:: $ cdrskin -v dev=/dev/hdc speed=12 fs=8m \; -sao -eject padsize=300k my_image.iso
Write compressed afio archive on-the-fly:: $ find . | afio -oZ - | \; cdrskin -v dev=0,1,0 fs=32m speed=8 \; -tao padsize=300k -
Write several sessions to the same CD, DVD-R[W] or DVD+R[/DL]:: $ cdrskin dev=/dev/hdc -v padsize=300k -multi -tao 1.iso; $ cdrskin dev=/dev/hdc -v padsize=300k -multi -tao 2.iso; $ cdrskin dev=/dev/hdc -v padsize=300k -multi -tao 3.iso; $ cdrskin dev=/dev/hdc -v padsize=300k -tao 4.iso
Get multi-session info for option -C of program mkisofs:: $ c_values=$(cdrskin dev=/dev/sr0 -msinfo 2>/dev/null); $ mkisofs ... -C "$c_values" ...
Inquire free space on media for a -tao -multi run:: $ x=$(cdrskin dev=/dev/sr0 -tao -multi \; --tell_media_space 2>/dev/null); $ echo "Available: $x blocks of 2048 data bytes"
Write audio tracks to CD:: $ cdrskin -v dev=ATA:1,0,0 speed=48 -sao \; track1.wav track2.au -audio -swab track3.raw
Get overview of the cdrecord compatible options:: $ cdrskin -help
Get overview of the non-cdrecord options:: $ cdrskin --help
Read the detailed manual page:: $ man cdrskin

Read about the standard for which cdrskin is striving:: $ man cdrecord; 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.)

Download as source code (see README):: cdrskin-0.4.4.pl00.tar.gz (715 KB).; The cdrskin tarballs are source code identical with libburn releases of the same version number. They get produced via a different procedure, though.
cdrskin is part of libburn - full libburn is provided with cdrskin releases.

Maintainers of cdrskin unstable packages please use SVN of libburnia-project.org

Download: svn co http://svn.libburnia-project.org/libburn/trunk libburn

Build: cd libburn ; ./bootstrap ; ./configure --prefix /usr ; make ; cdrskin/compile_cdrskin.sh

Build of SVN versions needs autotools of at least version 1.7 installed. But after the run of ./bootstrap, only vanilla tools like make and gcc are needed.

The following download is intended for adventurous end users or admins with full system souvereignty.

Source (./bootstrap is already applied, build tested, for more see upcoming README ):

Many thanks to Joerg Schilling for cdrecord,
and to Derek Foreman and Ben Jansens for creating libburn.
Historic versions based on Derek's and Ben's icculus.org/burn :
cdrskin-0.1.2.0.2.ts.tar.gz
cdrskin-0.1.3.0.2.ts.tar.gz
Very special thanks to Andy Polyakov whose dvd+rw-tools provide libburn with invaluable examples on how to deal with DVD media.

Example for a setup of device permissions. To be done by the superuser:
(CD devices which offer no rw-permission are invisible to normal users.): # cdrskin --devices; ...; 0 dev='/dev/sr0' rwrwr- : 'TEAC' 'CD-ROM CD-532S'; 1 dev='/dev/hdc' rwrw-- : 'LITE-ON' 'LTR-48125S'; # chmod a+rw /dev/sr0 /dev/hdc
