cdrtools (formerly known as cdrecord) is a collection of independent projects of free software/open source computer programs, created by Jörg Schilling and others.

The most important parts of the package are cdrecord, a console-based burning program; cdda2wav, a CD audio ripper that uses libparanoia; and mkisofs, a CD/DVD/BD/UDF/HFS filesystem image creator. Because these tools do not include any GUI, many graphical front-ends have been created.

Features

The collection includes many features, such as:

  • creation of audio, data, and mixed (audio and data) CDs.
  • burning CD-R, CD-RW and DVD-R, DVD-RW, DVD+R and DVD+RW, both single and dual layer DVDs.
  • several burning modes, such as Track-At-Once and Disc-At-Once
  • cue sheet based writing using the control file format from cdrwin including enhancements for ExactAudioCopy
  • ability to process Blu-ray Discs
  • understanding and exploitation of many vendor specific drive features.

History and name change

The first releases of cdrtools were called cdrecord because they only included the cdrecord tool and a few companion tools, but not mkisofs nor cdda2wav. In 1997, a copy of mkisofs[4] (developed at that time by Eric Youngdale) was included in the cdrecord package. In 1998, a copy of an experimental version of cdda2wav[5] (developed at that time by Heiko Eißfeldt) was included in the cdrecord package.

In 2000, Jörg Schilling changed the name of his package from "cdrecord" to "cdrtools"[6] to better reflect the fact that it had become a collection of tools.

Until 2006, cdrtools was the standard and most used software suite in its category on GNU/Linux systems as well as on several other operating systems (mainly BSD-based). It is still the most used[citation needed] software suite (in its category) on many open source operating systems, except for several major GNU/Linux distributions.

Licensing issues

The project was originally licensed under the GNU General Public License (GPL).

With version 1.11a17 (released in 2002), a section of cdrtools' source code was modified to include an invariant section, with the intent to prevent people from distributing variants with intentional bugs under the original name.[7] The purpose of this invariant section was to make sure any modification to cdrecord would be properly reported as such to the user.

In May 2006, most parts of cdrtools were switched to the CDDL with permission from their authors.[8] After this license change some parts of cdrtools (e.g. mkisofs, which is still GPL-licensed) use code that was switched to CDDL, (e.g. libscg, the SCSI Transport Layer developed by Jörg Schilling).

According to the Free Software Foundation, the CDDL is incompatible with the GNU General Public License (GPL).[9] Jonathan Corbet, founder of the LWN.net news source argued this makes it impossible to legally distribute cdrtools binaries.[10] Other observers claim that this license issue could be solved by using dynamic-link libraries (also called shared objects), that is, code under the GPL license may use code under the CDDL license (and vice-versa) as long as the codes are stored in distinct files (one runtime and one or more shared objects).[citation needed]

Because of this license change, several GNU/Linux distributions stopped distributing cdrtools in 2006.

The author's position is that any open source operating system can distribute cdrtools as long as the terms of the licenses are respected.[11][12]

In September 2006, four months after the license change, Jörg Schilling added support for dynamic-linking cdrtools,[13] hoping this would be enough for the GNU/Linux distributions to restart distributing cdrtools.

Debian,[14] Red Hat,[15][16] and Mandriva[17] have all either dropped cdrtools or reverted to the last non-CDDL release of cdrtools, and have not reverted that decision until now. Just before dropping cdrtools in 2006, the Debian project created cdrkit, a fork of cdrtools.[18] cdrkit is distributed by most of the GNU/Linux distributions which have dropped cdrtools. In August 2008, Mark Shuttleworth offered to ask the Software Freedom Law Center for a legal opinion on whether cdrtools could be included in Ubuntu, provided Schilling agreed to accept the opinion.[19]

cdrtools versus cdrkit versus libburnia

GNU/Linux distributions which still ship cdrkit consider it as legacy software and plan to move to libburnia,[20][21] which is not based on cdrtools.

Many operating system vendors, but not all, do distribute cdrtools. Because some major GNU/Linux distributions do not, several dedicated individuals have decided to help the community by providing unofficial 3rd-party builds of cdrtools. This table lists some popular operating systems, as well as some GNU/Linux distributions that ship cdrtools.

  37. ↑ Snippet from the genisoimage(1) man page: «UDF support is currently in alpha status and for this reason, it is not possible to create UDF-only images. UDF data structures are currently coupled to the Joliet structures, so there are many pitfalls with the current implementation. There is no UID/GID support, there is no POSIX permission support, there is no support for symlinks.»
  38. ↑ «xorriso does not produce UDF filesystems which are specified for official video DVD or BD.» Source: xorriso overview and xorriso(1) man page.
  39. ↑ genisoimage is compliant with Rock Ridge version 1.10 (producing the "RRIP_1991A" signature) but not with version 1.12, which has a "IEEE_1282" signature and embeds file serial numbers in the "PX" SUSP tags.
  40. ↑ The time stamp granularity with Rock Ridge extensions in mkisofs is 1 centi-second with the "-long-rr-time" option (enabled by default), and 1 second with the "-short-rr-time" option. The "-long-rr-time" option appeared with cdrtools 3.01a01 on 24 November 2010 (see AN-3.01a01). Warning: Linux systems can not handle sub-second time stamp granularity in Rock Ridge extensions and show 1 January 1970. This is why Linux users creating iso images with Rock Ridge extensions but without an UDF filesystem are advised to use the "-short-rr-time" option.
  41. ↑ The time stamp granularity in UDF filesystems created with mkisofs is 1 microsecond.
  42. ↑ Support for all three Unix times for Rock Ridge extensions was already available in mkisofs 1.11 which was shipped with cdrecord 1.5a1 on 22 June 1997. (Source: lines 376 to 380 of file cdrecord-1.5/mkisofs-1.11/rock.c of archive cdrecord-1.5a1.tar.gz)
  43. ↑ Support for all three Unix times for UDF was added to cdrtools 3.01a13 on 26 February 2013. (Source: AN-3.01a13)
  44. ↑ Support for all three Unix times in genisoimage is only available for Rock Ridge.
  45. ↑ Support for all three Unix times in xorriso is only available for Rock Ridge because xorriso does not create UDF filesystems.
  46. ↑ EFI boot support in mkisofs is available with the "-eltorito-platform efi" option.
  47. ↑ EFI boot support in genisoimage is available for Fedora/RHEL/CentOS (with an -E option). But it is missing in the non modified genisoimage.
  48. ↑ Although jigdo is a very usefull tool, the lack of built-in support for it in mkisofs is not a big issue since most users who create jigdo files already know how to use the stand-alone jigdo-file(1) command.
  49. ↑ An external POSIX-compliant find command can of course be used with genisoimage, but if the length of its output exceeds the maximum command line lengh, then genisoimage will not get the complete list of files.
  50. ↑ The -find option of xorriso is not POSIX-compliant and its syntax is very different from that of the find Unix command.
  51. ↑ Error control in mkisofs may be specified with the "errctl=" option.
  52. ↑ icedax is not installed with setuid access rights and as a result can only use functions that are available to unpriviledged users. This prevents vendor specific commands that deliver better DAE quality in edge cases.
