cdrskin

Limited cdrecord compatibility wrapper for libburn

Purpose:

Hardware requirements:

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.

or FreeBSD (with libc, of course) :

ATAPI/CAM support has to be enabled in the kernel, see atapicam(4).

libpthread

is supposed to be a standard system component.

GPL software included:

libburn-0.6.4

(founded by Derek Foreman and Ben Jansens, developed and maintained since August 2006 by Thomas Schmitt from team of libburnia-project.org)

transfers data to CD, DVD, BD

This program system has been tested on Intel/AMD Linux and FreeBSD 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 all DVD media except DVD-R DL, cdrskin is able to perform any recording job which is possible with cdrecord. Other than with cdrecord, option -multi is supported with many DVD types and BD-R. Write mode -tao works with anything but quickly blanked DVD-RW.

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

Prepare CD-RW or DVD-RW for re-use, DVD-RAM or BD-RE for first use:

$ cdrskin -v dev=/dev/sg1 blank=as_needed -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 \

  blank=as_needed -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 \

  blank=as_needed padsize=300k -

Write several sessions to the same CD, DVD-R[W] or DVD+R[/DL]:

$ cdrskin dev=/dev/hdc -v padsize=300k -multi 1.iso

$ cdrskin dev=/dev/hdc -v padsize=300k -multi 2.iso

$ cdrskin dev=/dev/hdc -v padsize=300k -multi 3.iso

$ cdrskin dev=/dev/hdc -v padsize=300k 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 -multi run:

$ x=$(cdrskin dev=/dev/sr0 -multi \

  --tell_media_space 2>/dev/null)

$ echo "Available: $x blocks of 2048 data bytes"

Accelerate BD-RE writing to full nominal speed after the first 250 MB

$ cdrskin ... stream_recording=250m ...

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.)

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 how to setup K3b to use cdrskin for burning data CD projects.
(K3b is a GUI frontend which uses cdrecord for CD burning.)
