Build and Installation
From tarball
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://svn.libburnia-project.org/libburn/trunk libburn
go into directory libburn and apply autotools by
./bootstrap
Obtain libburn-1.5.6.tar.gz, take it to a directory of your choice and do:
Alternatively you may unpack a release tarball for which you do not need
autotools installed.
tar xzf libburn-1.5.6.tar.gz
cd libburn-1.5.6
To build a libburnia-project.org subproject it should be sufficient to go
into its toplevel directory (here: "libburn") and execute
./configure --prefix=/usr
make
To make libburn accessible for running and application development,
and to install the cdrecord compatibility binary cdrskin, do
(as Superuser):
To make libburn accessible for running resp. application development,
and to install the cdrecord compatibility binary cdrskin, do:
make install
This procedure installs libburn.so.4 and cdrskin depending on it.
Above procedure installs cdrskin depending on libburn.so.4 .
For a standalone cdrskin binary, see cdrskin/README.
A behavioral conflict is known between any burn software and demons like hald
which probe CD drives. This can spoil burn runs for CD-R or CD-RW.
You may have to keep your hald away from the drive. See for example
http://www.freebsd.org/gnome/docs/halfaq.html
An important part of the project, libisofs, is hosted in a bzr repository at
launchpad.net :
bzr branch lp:libisofs
From git
Our build system is based on autotools. For preparing the build of a git
snapshot you will need autotools of at least version 1.7.
Do in a directory of your choice:
git clone https://dev.lovelyhq.com/libburnia/libburn.git libburn-git
cd libburn-git
./bootstrap
./configure --prefix=/usr
make
make install
Warning: The master branch might contain experimental features which might
not persist until next release.
Special ./configure options
make install on GNU/Linux will try to run program ldconfig with the library
installation directory as only argument. Failure to do so will not abort
installation. One may disable ldconfig by ./configure option:
--disable-ldconfig-at-install
In some situations Linux may deliver a better write performance to drives if
the track input is read with O_DIRECT (see man 2 open). The API call
burn_os_open_track_src() and the input readers of cdrskin and libburn fifo
can be told to use this peculiar read mode by:
--enable-track-src-odirect
But often libburn call burn_write_opts_set_dvd_obs(opts, 64*1024) will yield
even better performance in such a situation. 64k can be made default at
configure time by:
--enable-dvd-obs-64k
This may be combined with above --enable-track-src-odirect .
If it is desired that DVD DAO writing and stdio: writing get padded up to
a full write chunk of 32k or 64k, then use ./configure option:
--enable-dvd-obs-pad
Alternatively the transport of SCSI commands can be done via libcdio-0.83.
You may install it and re-run libburn's ./configure with option
--enable-libcdio
By use of a version script, the libburn.so library exposes no other function
names but those of the API definition in libburn/libburn.h.
If -Wl,--version-script=... makes problems with the local compiler, then
disable this encapsulation feature by
--disable-versioned-libs
Make sure to re-compile all source files after running ./configure
make clean ; make
make install
Linux only:
libburn tries to avoid a collision with udev's drive examination by waiting
0.1 seconds before opening the device file for a longer time, after udev
might have been alarmed by drive scanning activities.
The waiting time can be set at ./configure time with microsecond granularity.
E.g. 2 seconds:
CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=2000000"
./configure ...options...
Waiting can be disabled by zero waiting time:
CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=0"
Alternatively, libburn can try to be nice by opening the device file,
closing it immediately, waiting, and only then opening it for real:
CFLAGS="$CFLAGS -DLibburn_udev_extra_open_cyclE -DLibburn_udev_wait_useC=500000"

libburnia-project.org is an open-source software project for reading, mastering
and writing optical discs.
For now this means CD media, all DVD media, all BD media.
For now this means only CD media and all single layer DVD media except DVD+R.
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.
Currently it is supported on GNU/Linux with kernels >= 2.4,
on FreeBSD with ATAPI/CAM enabled in the kernel (see man atapicam),
on OpenSolaris (tested with kernel 5.11),
on NetBSD (tested with 6.1.3).
On other X/Open compliant systems there will only be pseudo drives, but no
direct MMC operation on real CD/DVD/BD drives.
For full ports to other systems we would need : login on a development machine
or 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.

data loss in older sessions if xorriso was used underneath growisofs.
Affected are releases since libisoburn-0.3.2 in january 2009.
- 25 Aug 2009 libisofs-0.6.22 can record MD5 checksums for the whole session
and for each single data file. Checksum tags can be used to verify superblock

supported profiles. It works around some pitfalls with U3 enhanced memory
sticks which emulate a CD-ROM.
- 27 Aug 2009 libisoburn-0.4.0.pl00 can record MD5 checksums by which one may
verify the session or single data files in the image. When comparing image
files with files in the local filesystem, the MD5 sums avoid the need for

technological overhaul but shall emphasize the maturity of the software.
libisofs-1.0.0 fixes a bug about the length of ECMA-119 directory names and
is ready to store untranslated ECMA-119 names (violating the specs).
libburn-1.0.0.pl00 is now willing to create stdio-drive files with
rw-permissions for all, if umask really asks for it. cdrskin now refuses
to burn if the foreseeable size exceeds media capacity
libisoburn-1.0.0.pl00 can now create an ISO 9660:1999 directory tree,
improved the emulation fidelity of command -as mkisofs, lowered the default

inside the ISO filesystem.
libburn removed a compilation obstacle on Solaris 9 and improved recognition
of stdio pseudo-drives.
libisoburn and xorriso fix bugs and make use of the new libisofs capability.
xorriso improves its mkisofs emulation.
- Thu Mar 10 2011 release 1.0.4:
Several bugs were fixed in the libraries and in the mkisofs emulation of
xorriso. This emulation xorrisofs has now an own man page and info document.
- Sat Apr 09 2011 release 1.0.6:
libburn refined its representation of emulated drives. The size alignment
of DVD DAO is now 2 kB rather than 32 kB. libisofs produces Joliet names of
up to 103 characters. xorriso fixes two bugs and makes use of the library
improvements.
- Thu Apr 14 2011 release libisoburn-1.0.8:
A bug in the mkisofs emulation of xorriso could cause options to be ignored.
The problem was freshly introduced with libisoburn-1.0.6.

- Mon Jun 20 2011 patch release libburn-1.1.0.pl01:
libburn-1.1.0 compiled only on Linux, FreeBSD, and Solaris, but not on
other X/Open compliant systems.
- Fri Jul 08 2011 release libisofs-1.1.2 and libisoburn-1.1.2:
A severe regression was fixed in libisoburn and xorriso, which was introduced
with version 1.0.6. It caused ISO 9660 images to be unreadable if they were
written to a write-only random-access file. E.g. by: xorrisofs ... >image.iso
- Mon Aug 08 2011 release 1.1.4:
Several bugs were fixed in libburn. The most severe of them prevented xorriso
on some drives from burning mountable ISO 9660 images to CD media.
New means to list drives by their udev symbolic links help to deal with
the non-persistent drive addresses on modern GNU/Linux.
- Tue Sep 27 2011 release 1.1.6:
libisoburn now comes with a test suite. See releng/README. Bugs were fixed
in several rarely used features. Processing of ACL and extattr was enabled
on FreeBSD. Workarounds try to cope with vanishing udev links on GNU/Linux.
- Mon Nov 21 2011 release libburn-1.1.8 and libisoburn-1.1.8:
libburn avoids to close and open drive device files while operating on them.

improvements. Some rarely occurring bugs have been fixed.
- Fri Jul 20 2012 release 1.2.4:
libburn and libisofs got some rarely occurring bugs fixed. libisofs learned
to produce HFS+ metadata and Apple Partition Map. The capabilities of
isohybrid options --efi and --mac have been implemented (GPT and APM).
- Tue Jan 08 2013 release 1.2.6:
Small improvements were made in libburn. Minor bugs were fixed in the
libraries. xorriso improved its capabilities to serve the needs of frontend
programs. A proof of concept for a GUI frontend has been implemented:
xorriso-tcltk
- Mon Mar 18 2013 release 1.2.8:
Some rarely occurring bugs were fixed in libisofs and libburn. libburn's
handling of incomplete sessions has been improved. xorriso's mkisofs
emulation learned to set El Torito section id strings.
- Fri May 17 2013 release 1.3.0:
Several bugs were fixed in the libraries and in xorriso. The recently
introduced new boot preparation capabilities have been tested. New
boot preparation options for GRUB2 were added.

- Fri Aug 07 2013 release 1.3.2:
cdrskin has acquired the capability to copy audio tracks to .wav files.
It can extract CD-TEXT in a form that is readable for humans and for
cdrskin itself. Several small bugs were fixed in xorriso. Its capabilities
to serve frontend programs in dialog mode have been improved.
- Thu Dec 12 2013 release 1.3.4:
A long standing hidden bug was fixed, which affected inspection of
unformatted DVD+RW.
xorriso now by default puts EL Torito boot images to low block addresses.
It can report and set read speeds. Several rarely occurring bugs were fixed.
- Tue Mar 04 2014 release 1.3.6:
libburn learned to operate optical drives and media on NetBSD. libisofs got
a bug fix about HFS+ and enhancements about character set conversion.
Minor bugs were fixed in libisoburn. xorriso can now find files with names
which cannot be represented unchanged in ECMA-119, Joliet, or HFS+.
- Sat Jun 28 2014 release 1.3.8:
libburn got several bugs fixed. libisofs offers new API calls for inspection
of boot sectors in ISO 9660 filesystems. xorriso improved its support for
NetBSD, offers new features with command -find, and a command to extract
ISO 9660 file content onto standard output or into filter processes.
- Sun May 17 2015 release 1.4.0:
This release is mainly about bug fixes and a new feature of xorriso to
propose commands or as_mkisofs options which can reproduce the boot
equipment of the loaded ISO filesystem.
- Sat Nov 28 2015 release 1.4.2:
libburn got some bugs fixed and learned to inquire the drive serial number.
libisofs now sorts data file content by ECMA-119 file names for better
reproducability of ISO content. Rock Ridge filenames may be restricted to
lengths between 64 and 255 bytes. If needed, a qualified truncation happens.
xorriso now can replay boot settings when modifying ISO filesystems.
In order to avoid clogging of concurrent Linux SG_IO, xorriso got command
-modesty_on_drive to enable an old workaround from IDE master/slave days.
The source code underwent a scan by Coverity. About 150 code changes
resulted, but no easy-to-trigger bugs were found.
- Fri Jan 29 2016 patch release libburn-1.4.2.pl01:
cdrskin did not work with "-" (stdin) as input.
Regression introduced by version 1.4.2.
- Fri Jul 01 2016 release 1.4.4:
The capability to use Linux /dev/sg was revived in order to circumvent the
sr_mutex lock which hampers concurrent use of optical drives via SG_IO.
libisofs now can use appended partitions by El Torito, avoiding the need
for duplicate EFI System Partition images.
Several bugs have been fixed.
- Fri Sep 16 2016 release 1.4.6:
libburn now operates optical drives on OpenBSD. libisofs makes pseudo-random
id generation reproducible by relating it to the volume date.
xorriso interprets environment variable SOURCE_DATE_EPOCH of
reproducible-builds.org to prepare a default setting which leads to identical
ISO images on identical input and identical constant options.
Several moderately embarrassing bugs have been fixed.
- Tue Sep 12 2017 release 1.4.8:
libburn now refuses to write to SRM+POW formatted BD-R, because it would
spoil them. libisofs got several bugs fixed and offers new API calls to
support new xorriso features. libisoburn and xorriso offer more detail
control with particular boot sector types. New bugs and a regression from
version 1.4.4 were fixed.
- Sat Sep 15 2018 release 1.5.0
libisofs now can record all xattr namespaces, user defined padding was moved
after appended partitions. libisoburn and xorriso make use of the new xattr
capability of libisofs.
All three libraries got some rarely triggered bugs fixed.
- Sat Oct 26 2019 release 1.5.2
The libraries are now ready for building out-of-source. libisofs got minor
API extensions. libburn got a bug fixed which spoiled burn runs on
some MATSHITA laptop drives. It is now able to list all features which
the drive announces. xorriso can now set GPT type GUIDs with appended
partitions and the ISO partition.
All three libraries got some rarely triggered bugs fixed.
- Mon Nov 25 2019 patch release 1.5.2.pl01
cdrskin did not properly burn multiple tracks. Track 1 was slow and burning
stalled before track 2. Regression introduced by 1.5.0.
- Sat Jan 30 2021 , 07 Feb 2021 release 1.5.4
libburn offers new opportunities to influence drive speed.
libisofs got a bug fixed which under medium rare circumstances spoiled
zisofs production. libisofs switched to usage of libjte-2.0.0. Further it
can now write and read zisofs2 format, which enables compression of files
>= 4 GiB. When reading Joliet file trees, the names get stripped of their
version numbers by default. After loading metadata, libisofs can now tell
which directory tree was loaded and whether Rock Ridge is used.
libisoburn and xorriso make use of these new features.
xorriso can put out the data stream of -check_media to standard output. It
can restore files with many zero bytes as sparse files and it is able to
extract recognized boot images into data files on hard disk.
A new script xorriso-dd-target helps to put an ISO image onto an USB stick
without endangering valuable hard disk content.
Several rarely triggered bugs were fixed.
- Wed Jun 07 2023 release 1.5.6
libburn can overburn CD media, i.e. write more data than the drive announced
as medium capacity.
libisofs can assess many of the features which were in effect when a
given ISO 9660 filesystem was created. A safety limit was introduced not
to exceed the limit of Linux which is imposed on the number of SUSP CE
entries which is good for about 60 KiB of AAIP data. Some rarely occuring
bugs were fixed in libisofs.
libisoburn and xorriso expose the new library features to the user and
got some minor improvements. Many minor bugs were fixed.

cdrskin is a limited cdrecord compatibility wrapper which allows to use
most of the libburn features from the command line.
Currently it is fully supported on GNU/Linux with kernels >= 2.4, on FreeBSD,
on OpenSolaris, and on NetBSD.
IDE drives under Linux 2.4 need kernel module ide-scsi.
ATA and SATA drives under FreeBSD need kernel module atapicam.
On other X/Open compliant systems there will only be emulated drives, but no
direct MMC operation on real CD/DVD/BD drives.
Currently it is only supported on Linux with kernels >= 2.4.

During write operations DVD-RAM and BD-RE automatically apply defect

and media produce flawless results anyway, then one can try to reach full
nominal speed by option "stream_recording=on".
In this case bad blocks are not detected during write and not even previously
known bad blocks are avoided. So you have to make your own readability tests
and go back to half speed as soon as the first read errors show up.
Instead of "on" one may also set a start address for stream recording.

the media and accelerate when writing to higher addresses.

In some situations Linux may deliver a better write performance to drives if
the track input is read with O_DIRECT (see man 2 open). The API call
burn_os_open_track_src() and the input readers of cdrskin and libburn fifo
can be told to use this peculiar read mode by:
--enable-track-src-odirect
But often cdrskin option dvd_obs=64k will yield even better performance in
such a situation. 64k can be made default at compile time by
cdrskin/compile_cdrskin.sh -dvd_obs_64k
It can also be enabled at configure time by
./configure ... --enable-dvd-obs-64k ...

libburn tries to avoid a collision with udev's drive examination by waiting
0.1 seconds before opening the device file for a longer time, after udev
might have been alarmed by drive scanning activities.
The waiting time can be set at ./configure time with microsecond granularity.
E.g. 2 seconds:

./configure ...options...
Waiting can be disabled by zero waiting time:

closing it immediately, waiting, and only then opening it for real:

System Dependend Drive Permission Examples
Accessing the optical drives requires privileges which usually are granted
only to the superuser. Linux, FreeBSD, Solaris, NetBSD, offer quite different
approaches for avoiding the need for unrestricted privileges.
First check whether some friendly system setting already allows you to
access the drives as normal user:
cdrskin --devices
Those drives of which you see address and type strings are already usable.
If there remain drives invisible which the superuser can see by the same
command, then the following examples might help:
---------------
On all systems:
---------------
Add the authorized users of CD drives to group "floppy" in /etc/group.
If missing: create this group.
Changes to /etc/group often only affect new login sessions. So log out and in
before making the first tests.
---------
On Linux:
---------
Allow rw-access to the drives
chgrp floppy /dev/sr0 /dev/sr1
chmod g+rw /dev/sr0 /dev/sr1
It might be necessary to perform chgrp and chmod after each reboot or to
edit distro dependent device configuration files for permanent settings.
-----------
On FreeBSD:
-----------
Edit /etc/devfs.rules and make sure to have these lines
[localrules=10]
add path 'acd*' mode 0664 group floppy
add path 'cd*' mode 0664 group floppy
add path 'pass*' mode 0664 group floppy
add path 'xpt*' mode 0664 group floppy
[localrules=5]
add path 'pass*' mode 0664 group floppy
add path 'cd*' mode 0664 group floppy
add path 'xpt*' mode 0664 group floppy
add path 'acd*' mode 0664 group floppy
Edit /etc/rc.conf and add the following line if missing
devfs_system_ruleset="localrules"
This gets into effect by reboot or by command
/etc/rc.d/devfs start
-----------
On Solaris:
-----------
Run cdrskin by
pfexec cdrskin ...arguments...
The following settings will make pfexec keep original UID and EUID and prevent
most superuser powers. Be aware that you still can manipulate all device files
if you have the file permissions for that.
Full root privileges for cdrskin can then be acquired only by command su.
Edit /etc/security/exec_attr and add this line to the other "Media Backup"
lines:
Media Backup:solaris:cmd:::/usr/local/bin/cdrskin:privs=basic,sys_devices
Edit /etc/user_attr and add profile "Media Backup" to the user's line:
thomas::::profiles=Media Backup,Primary Administrator;roles=root
See also man privileges, man exec_attr, man user_attr.
Then allow the group r-access to the drives
pfexec chgrp floppy /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
pfexec chmod g+r /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
The last two commands have to be executed after each boot. I do not know
the relevant device configuration files yet.
----------
On NetBSD:
----------
Allow rw-access to the drives
chgrp floppy /dev/rcd[01]d
chmod g+rw /dev/rcd[01]d

CD-TEXT from the view of the user:
CD-TEXT records attributes of disc and tracks on audio CD.
The attributes are grouped into blocks which represent particular languages.
Up to 8 blocks are possible.
There are 13 defined attribute categories, which are called Pack Types and are
identified by a single-byte code:
0x80 = Title
0x81 = Names of Performers
0x82 = Names of Songwriters
0x83 = Names of Composers
0x84 = Names of Arrangers
0x85 = Messages
0x86 = text-and-binary: Disc Identification
0x87 = text-and-binary: Genre Identification
0x88 = binary: Table of Content information
0x89 = binary: Second Table of Content information
(0x8a to 0x8c are reserved.)
0x8d = Closed Information
0x8e = UPC/EAN code of the album and ISRC code of each track
0x8f = binary: Size Information of the Block
Some of these categories apply to the whole disc only:
0x86, 0x87, 0x88, 0x89, 0x8d
Some have to be additionally attributed to each track, if they are present for
the whole disc:
0x80, 0x81, 0x82, 0x83, 0x84, 0x85, 0x8e
One describes the overall content of a block and in part of all other blocks:
0x8f
The total size of a block's attribute set is restricted by the fact that it
has to be stored in at most 253 records with 12 bytes of payload. These records
are called Text Packs.
A shortcut for repeated identical track texts is provided, so that a text
that is identical to the one of the previous track occupies only 2 or 4 bytes.
-------------------------------------------------------------------------------
Content specification of particular pack types:
Pack types 0x80 to 0x85 and 0x8e contain 0-terminated cleartext. If double byte
characters are used, then two 0-bytes terminate the cleartext.
The meaning of 0x80 to 0x85 should be clear by above list. They are encoded
according to the Character Code of their block. Either as ISO-8859-1 single
byte characters, or as 7-bit ASCII single byte characters, or as MS-JIS double
byte characters.
More info to 0x8e is given below.
Pack type 0x86 (Disc Identification) is documented by Sony as "Catalog Number:
(use ASCII Code) Catalog Number of the album". So it is not really binary
but might be non-printable, and should contain only bytes with bit7 = 0.
Pack type 0x87 contains 2 binary bytes, followed by 0-terminated cleartext.
The two binary bytes form a big-endian index to the following list.
0x0000 = "Not Used" (Sony prescribes to use this if no genre applies)
0x0001 = "Not Defined"
0x0002 = "Adult Contemporary"
0x0003 = "Alternative Rock"
0x0004 = "Childrens Music"
0x0005 = "Classical"
0x0006 = "Contemporary Christian"
0x0007 = "Country"
0x0008 = "Dance"
0x0009 = "Easy Listening"
0x000a = "Erotic"
0x000b = "Folk"
0x000c = "Gospel"
0x000d = "Hip Hop"
0x000e = "Jazz"
0x000f = "Latin"
0x0010 = "Musical"
0x0011 = "New Age"
0x0012 = "Opera"
0x0013 = "Operetta"
0x0014 = "Pop Music"
0x0015 = "Rap"
0x0016 = "Reggae"
0x0017 = "Rock Music"
0x0018 = "Rhythm & Blues"
0x0019 = "Sound Effects"
0x001a = "Spoken Word"
0x001b = "World Music"
Sony documents the cleartext part as "Genre information that would supplement
the Genre Code, such as 'USA Rock music in the 60s'". Always ASCII encoded.
Pack type 0x88 records information from the CD's Table of Content, as of
READ PMA/TOC/ATIP Format 0010b (mmc3r10g.pdf, table 237 TOC Track Descriptor
Format, Q Sub-channel).
See below, Format of a CD-TEXT packs array, for more details about the content
of pack type 0x88.
Pack type 0x89 is yet quite unclear. It might be a representation of Playback
Skip Interval, Mode-5 Q sub-channel, POINT 01 to 40 (mmc3r10g.pdf 4.2.3.6.3).
If so, then this seems not to apply to write type SAO, because the CUE SHEET
format offers no way to express Mode-5 Q.
See below, Format of a CD-TEXT packs array, for an example of this pack type.
Pack type 0x8d is documented by Sony as "Closed Information: (use 8859-1 Code)
Any information can be recorded on disc as memorandum. Information in this
field will not be read by CD TEXT players available to the public."
Always ISO-8859-1 encoded.
Pack type 0x8e is documented by Sony as "UPC/EAN Code (POS Code) of the album.
This field typically consists of 13 characters." Always ASCII encoded.
It applies to tracks as "ISRC code [which] typically consists of 12 characters"
and is always ISO-8859-1 encoded.
MMC calls these information entities Media Catalog Number and ISRC.
The catalog number consists of 13 decimal digits.
ISRC consists of 12 characters: 2 country code [0-9A-Z], 3 owner code [0-9A-Z],
2 year digits (00 to 99), 5 serial number digits (00000 to 99999).
Pack type 0x8f summarizes the whole list of text packs of a block.
See below, Format of a CD-TEXT packs array, for details.
-------------------------------------------------------------------------------
Format of a CD-TEXT packs array:
The attributes are represented on CD as Text Packs in the sub-channel of
the Lead-in of the disc. See doc/cookbook.txt for a description how to write
the readily formatted CD-TEXT pack array to CD, and how to read CD-TEXT packs
from CD.
The format is explained in part in MMC-3 (mmc3r10g.pdf, Annex J) and in part by
the documentation in Sony's cdtext.zip :
Each pack consists of a 4-byte header, 12 bytes of payload, and 2 bytes of CRC.
The first byte of each pack tells the pack type. See above for a list of types.
The second byte tells the track number to which the first text piece in
a pack is associated. Number 0 means the whole album. Higher numbers are
valid for types 0x80 to 0x85, and 0x8e. With these types, there should be
one text for the disc and one for each track.
With types 0x88 and 0x89, the second byte bears a track number, too.
With type 0x8f, the second byte counts the record parts from 0 to 2.
The third byte is a sequential counter.
The fourth byte is the Block Number and Character Position Indicator.
It consists of three bit fields:
bit7 = Double Bytes Character Code (0= single byte characters)
bit4-6 = Block Number (groups text packs in language blocks)
bit0-3 = Character position. Either the number of characters which
the current text inherited from the previous pack, or
15 if the current text started before the previous pack.
The 12 payload bytes contain pieces of 0-terminated texts or binary data.
A text may span over several packs. Unused characters in a pack are used for
the next text of the same pack type. If no text of the same type follows,
then the remaining text bytes are set to 0.
The CRC algorithm uses divisor 0x11021. The resulting 16-bit residue of the
polynomial division gets inverted and written as big-endian number to bytes
16 and 17 of the pack.
The text packs are grouped in up to 8 blocks of at most 256 packs. Each block
is in charge for one language. Sequence numbers of each block are counted
separately. All packs of block 0 come before the packs of block 1.
The limitation of block number and sequence numbers imply that there are at
most 2048 text packs possible. (READ TOC/PMA/ATIP could retrieve 3640 packs,
as it is limited to 64 kB - 2.)
If a text of a track (pack types 0x80 to 0x85 and 0x8e) repeats identically
for the next track, then it may be represented by a TAB character (ASCII 9)
for single byte texts, and two TAB characters for double byte texts.
(This should be used because 256 * 12 bytes is few space for 99 tracks.)
The two binary bytes of pack type 0x87 are written to the first 0x87 pack of
a block. They may or may not be repeated at the start of the follow-up packs
of type 0x87.
The first pack of type 0x88 in a block records in its payload bytes:
0 : PMIN of POINT A1 = First Track Number
1 : PMIN of POINT A2 = Last Track Number
2 : unknown, 0 in Sony example
3 : PMIN of POINT A2 = Start position of Lead-Out
4 : PSEC of POINT A2 = Start position of Lead-Out
5 : PFRAME of POINT A2 = Start position of Lead-Out
6 to 11 : unknown, 0 in Sony example
The following packs record PMIN, PSEC, PFRAME of the POINTs between the
lowest track number (min 01h) and the highest track number (max 63h).
The payload of the last pack is padded by 0s.
The Sony .TOC example:
A0 01
A1 14
A2 63:02:18
01 00:02:00
02 04:11:25
03 08:02:50
04 11:47:62
...
13 53:24:25
14 57:03:25
yields
88 00 23 00 01 0e 00 3f 02 12 00 00 00 00 00 00 12 00
88 01 24 00 00 02 00 04 0b 19 08 02 32 0b 2f 3e 67 2d
...
88 0d 27 00 35 18 19 39 03 19 00 00 00 00 00 00 ea af
Pack type 0x89 is yet quite unclear. Especially what the information shall
mean to the user of the CD. The time points in the Sony example are in the
time range of the tracks numbers that are given before the time points:
01 02:41:48 01 02:52:58
06 23:14:25 06 23:29:60
07 28:30:39 07 28:42:30
13 55:13:26 13 55:31:50
yields
89 01 28 00 01 04 00 00 00 00 02 29 30 02 34 3a f3 0c
89 06 29 00 02 04 00 00 00 00 17 0e 19 17 1d 3c 73 92
89 07 2a 00 03 04 00 00 00 00 1c 1e 27 1c 2a 1e 72 20
89 0d 2b 00 04 04 00 00 00 00 37 0d 1a 37 1f 32 0b 62
The track numbers are stored in the track number byte of the packs. The two
time points are stored in byte 6 to 11 of the payload. Byte 0 of the payload
seems to be a sequential counter. Byte 1 always 4 ? Byte 2 to 5 always 0 ?
Pack type 0x8f summarizes the whole list of text packs of a block.
So there is one group of three 0x8f packs per block.
Nevertheless each 0x8f group tells the highest sequence number and the
language code of all blocks.
The payload bytes of three 0x8f packs form a 36 byte record. The track number
bytes of the three packs have the values 0, 1, 2.
Byte :
0 : Character code for pack types 0x80 to 0x85:
0x00 = ISO-8859-1
0x01 = 7 bit ASCII
0x80 = MS-JIS (japanese Kanji, double byte characters)
1 : Number of first track
2 : Number of last track
3 : libcdio source states: "cd-text information copyright byte"
Probably 3 means "copyrighted", 0 means "not copyrighted".
4 - 19 : Pack count of the various types 0x80 to 0x8f.
Byte number N tells the count of packs of type 0x80 + (N - 4).
I.e. the first byte in this field of 16 counts packs of type 0x80.
20 - 27 : Highest sequence byte number of blocks 0 to 7.
28 - 36 : Language code for blocks 0 to 7 (tech3264.pdf appendix 3)
Not all of these Codes have ever been seen with CD-TEXT, though.

-------------------------------------------------------------------------------
Overview of libburn API calls for CD-TEXT (see libburn/libburn.h for details):
libburn can retrieve the array of text packs from a CD:
int burn_disc_get_leadin_text(struct burn_drive *d,
unsigned char **text_packs, int *num_packs,
int flag);
It can write a text pack set with a CD SAO session.
This set may be attached as array of readily formatted text packs by:
int burn_write_opts_set_leadin_text(struct burn_write_opts *opts,
unsigned char *text_packs,
int num_packs, int flag);
The array of text packs may be read from a file by
int burn_cdtext_from_packfile(char *path, unsigned char **text_packs,
int *num_packs, int flag);
Alternatively the pack set may be defined by attaching CD-TEXT attributes
to burn_session and burn_track:
int burn_session_set_cdtext_par(struct burn_session *s,
int char_codes[8], int copyrights[8],
int languages[8], int flag);
int burn_session_set_cdtext(struct burn_session *s, int block,
int pack_type, char *pack_type_name,
unsigned char *payload, int length, int flag);
int burn_track_set_cdtext(struct burn_track *t, int block,
int pack_type, char *pack_type_name,
unsigned char *payload, int length, int flag);
Macros list the texts for genre and language codes:
BURN_CDTEXT_LANGUAGES_0X00
BURN_CDTEXT_FILLER
BURN_CDTEXT_LANGUAGES_0X45
BURN_CDTEXT_GENRE_LIST
BURN_CDTEXT_NUM_GENRES
There is a reader for Sony Input Sheet Version 0.7T:
int burn_session_input_sheet_v07t(struct burn_session *session,
char *path, int block, int flag);
and a writer which converts an array of text packs to such a Sony Input Sheet:
int burn_make_input_sheet_v07t(unsigned char *text_packs, int num_packs,
int start_tno, int track_count,
char **result, int *char_code, int flag);
CD-TEXT can be read from a CDRWIN cue sheet file which defines the tracks
of a session
int burn_session_by_cue_file(struct burn_session *session,
char *path, int fifo_size, struct burn_source **fifo,
unsigned char **text_packs, int *num_packs, int flag);
The session and track attributes can then be converted into an array of
text packs by:
int burn_cdtext_from_session(struct burn_session *s,
unsigned char **text_packs, int *num_packs,
int flag);
or they can be written as array of text packs to CD when burning begins and
no array of pre-formatted packs was attached to the write options by
burn_write_opts_set_leadin_text().
There are calls for inspecting the attached attributes:
int burn_session_get_cdtext_par(struct burn_session *s,
int char_codes[8], int copyrights[8],
int block_languages[8], int flag);
int burn_session_get_cdtext(struct burn_session *s, int block,
int pack_type, char *pack_type_name,
unsigned char **payload, int *length, int flag);
int burn_track_get_cdtext(struct burn_track *t, int block,
int pack_type, char *pack_type_name,
unsigned char **payload, int *length, int flag);
and for removing attached attributes:
int burn_session_dispose_cdtext(struct burn_session *s, int block);
int burn_track_dispose_cdtext(struct burn_track *t, int block);
UPC/EAN and ISRC not only affect CD-TEXT but also information that is written
along with the tracks in Q sub-channel. These can be influenced by
burn_session_input_sheet_v07t(), burn_session_by_cue_file() and by
void burn_write_opts_set_mediacatalog(struct burn_write_opts *opts,
unsigned char mediacatalog[13]);
void burn_write_opts_set_has_mediacatalog(struct burn_write_opts *opts,
int has_mediacatalog);
void burn_track_set_isrc(struct burn_track *t, char *country, char *owner,
unsigned char year, unsigned int serial);
int burn_track_set_isrc_string(struct burn_track *t, char isrc[13],
int flag);
-------------------------------------------------------------------------------
Sony Text File Format (Input Sheet Version 0.7T):
This text file format provides comprehensive means to define the text
attributes of session and tracks for a single block. More than one
such file has to be read to form an attribute set with multiple blocks.
The information is given by text lines of the following form:
purpose specifier [whitespace] = [whitespace] content text
[whitespace] is zero or more ASCII 32 (space) or ASCII 9 (tab) characters.
The purpose specifier tells the meaning of the content text.
Empty content text does not cause a CD-TEXT attribute to be attached.
The following purpose specifiers apply to the session as a whole:
Specifier = Meaning
-------------------------------------------------------------------------
Text Code = Character code for pack type 0x8f
"ASCII", "8859"
Language Code = One of the language names for pack type 0x8f
Album Title = Content of pack type 0x80
Artist Name = Content of pack type 0x81
Songwriter = Content of pack type 0x82
Composer = Content of pack type 0x83
Arranger = Content of pack type 0x84
Album Message = Content of pack type 0x85
Catalog Number = Content of pack type 0x86
Genre Code = One of the genre names for pack type 0x87
Genre Information = Cleartext part of pack type 0x87
Closed Information = Content of pack type 0x8d
UPC / EAN = Content of pack type 0x8e
Text Data Copy Protection = Copyright value for pack type 0x8f
"ON" = 0x03, "OFF" = 0x00
First Track Number = The lowest track number used in the file
Last Track Number = The highest track number used in the file
The following purpose specifiers apply to particular tracks:
Track NN Title = Content of pack type 0x80
Track NN Artist = Content of pack type 0x81
Track NN Songwriter = Content of pack type 0x82
Track NN Composer = Content of pack type 0x83
Track NN Arranger = Content of pack type 0x84
Track NN Message = Content of pack type 0x85
ISRC NN = Content of pack type 0x8e
The following purpose specifiers have no effect on CD-TEXT:
Remarks = Comments with no influence on CD-TEXT
Disc Information NN = Supplementary information for use by record companies.
ISO-8859-1 encoded. NN ranges from 01 to 04.
Input Sheet Version = "0.7T"
libburn peculiarties:
libburn may read files of the described format by
burn_session_input_sheet_v07t()
after the burn_session has been establiched and all burn_track objects have
been added. It can convert an array of CD-TEXT packs into this format by
burn_make_input_sheet_v07t()
The following purpose specifiers accept byte values of the form 0xXY.
Text Code , Language Code , Genre Code , Text Data Copy Protection
E.g. to indicate MS-JIS character code (of which the exact name is unknown):
Text Code = 0x80
Genre Code is settable by 0xXY or 0xXYZT or 0xXY 0xZT.
Genre Code = 0x001b
Purpose specifiers which have the meaning "Content of pack type 0xXY"
may be replaced by the pack type codes. E.g.:
0x80 = Session content of pack type 0x80
Track 02 0x80 = Track content of pack type 0x80 for track 2.
Applicable are pack types 0x80 to 0x86, 0x8d, 0x8e.
Text Code may be specified only once. It gets speficied to "ISO-8850-1"
automatically as soon as content is defined which depends on the text
encoding of the block. I.e with pack types 0x80 to 0x85.
If a track attribute is set, but the corresponding session attribute is not
defined or defined with empty text, then the session attribute gets attached
as empty test. (Normally empty content is ignored.)

CDRWIN cue sheet files:
A CDRWIN cue sheet file defines the track data source (FILE), various text
attributes (CATALOG, TITLE, PERFORMER, SONGWRITER, ISRC), track block types
(TRACK), track start addresses (INDEX).
The rules for CDRWIN cue sheet files are described at
http://digitalx.org/cue-sheet/syntax/
There are three more text attributes mentioned in man cdrecord for defining
the corresponding CD-TEXT attributes: ARRANGER, COMPOSER, MESSAGE.

@section intro Introduction
Libburnia is an open-source project for reading, mastering and writing
optical discs. This page is about its capability to handle optical media.
optical discs.
For now this means CD-R, CD-RW, DVD-RAM, DVD+RW, DVD+R, DVD+R/DL, DVD-RW,
DVD-R, DVD-R/DL, BD-R, BD-RE.
DVD-R, BD-RE.
Our scope is currently Linux 2.4 and 2.6, FreeBSD, OpenSolaris, or NetBSD.
For ports to other systems we would need : login on a development machine or
an OS that is installable on an AMD 64-bit PC, advise from a system person
about the equivalent of Linux sg or FreeBSD CAM, volunteers for testing of
realistic use cases.
Not supported yet are DVD-R/DL, HD-DVD, BD-R (blue ray). Testers for
DVD-R/DL are wanted, though. BD-R programming efforts would be made
if an interested tester contacts us.
libburn is the library by which preformatted data get onto optical media.
Its code is independent of cdrecord. Its DVD capabilities are learned from
studying the code of dvd+rw-tools and MMC-5 specs. No code but only the pure
SCSI knowledge has been taken from dvd+rw-tools, though.
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.
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. Additionally it provides libburn's DVD/BD capabilities,
where only -sao is compatible with 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.
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.
The burn API example of libburn is named test/libburner.c . The API for media
information inquiry is demonstrated in test/telltoc.c .
Explore these examples if you look for inspiration.
We have a well tested code base for burning data and audio CDs and many DVD
types. 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.
SONAME:
ISO 9660 filesystems with Rock Ridge and Joliet extensions can be created
and manipulated quite freely. This capability together with our burn capability
makes possible a single binary application which covers all steps of image
composition, updating and writing. Quite unique in the Linux world.
@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/srM or /dev/hdX (e.g. on kernel 2.6).
libburn is the foundation of our cdrecord emulation. Its code is
independent of cdrecord. Its DVD capabilities are learned from
studying the code of dvd+rw-tools and MMC-5 specs. No code but only
the pure SCSI knowledge has been taken from dvd+rw-tools, though.
- 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.
- libisoburn is an add-on to libburn and libisofs which coordinates both and
also allows to grow ISO-9660 filesystem images on multi-session
media as well as on overwriteable media via the same API.
All media peculiarities are handled automatically.
- 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. Additionally it
provides libburn's DVD/BD capabilities, where only -sao is
compatible with 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.
- xorriso is an application of all three libraries which creates, loads,
manipulates and writes ISO 9660 filesystem images with
Rock Ridge extensions. Manipulation is not only adding or
overwriting of files but also deletion, renaming, and attribute
changing. An incremental backup feature is provided.
See xorriso/README for more
- "test" is a collection of application gestures and examples given by the
authors of the library features. The burn API example of libburn
is named test/libburner.c . The API for media information inquiry is
demonstrated in test/telltoc.c .
Explore these examples if you look for inspiration.
We strive to be a responsive upstream.
Our libraries are committed to maintain older feature sets in newer versions.
This applies to source code headers (API) as well as to linkable objects (ABI).
The only exception from this rule is about non-release versions x.y.*[13579]
which are allowed to introduce new features, change those new features in
any way and even may revoke such new features before the next release of
x.y.*[02468]. As soon as it is released, a feature is promised to persist.
SONAMES:
libburn.so.4 (since 0.3.4, March 2007),
libisofs.so.6 (since 0.6.2, February 2008),
libisoburn.so.1 (since 0.1.0, February 2008).
@section using Using libburn

@section libburner Libburner
libburner is a minimal demo application for the library libburn
(see: libburn/libburn.h) as provided on http://libburnia-project.org .
It can list the available devices, can burn to recordable CD, DVD, or BD,
can blank a CD-RW or DVD-RW, and can format unformatted DVD-RW, BD-R, or BD-RE.

TNO is the track number. The TNO of the first track may be chosen in the range
of 1 to 99. The TNO of following tracks must be the TNO of their predecessor
plus 1. The last track must not have a TNO larger than 99.
INDEX is a subaddress within tracks. INDEX 1 is mandatory and marks the start
of the payload area of a track. The range between INDEX 0 and 1 is called
pre-gap. It should contain zeros if it exists. Further cue sheet entries with
consecutive INDEX numbers mark ranges within the track. The range of the last
index may contain a post-gap with zeros.
ADR is always 01h.

of the track (to be used with next track or with lead-out).
There may be more entries with INDEX 2 to 99. Their MSF address tells the
sector where their range starts. This range ends at the MSF of the next entry
in the cue sheet. INDEX information is stored in the sub-channel of the sectors
but not in the Table-of-Content of the disc.

ISO 9660 multi-session emulation on overwriteable media :
Overwriteable media provide a single overwriteable track which may grow up to
the full media capacity. There is no builtin table-of-content which records
the history of write sessions.
mount -t iso9660 will use sbsector=0 as default.
The term "superblock" shall depict the first 64 KiB after the sbsector address.
ISO 9660 multi-session depends on typical TOC information in two ways:
It needs the superblock address MSC1 of the most recently recorded session and
it needs the Next Writeable Address NWA for which to prepare the address
offset.
The following is learned from growisofs and from ECMA-119:
http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-119.pdf
ISO 9660 filesystems provide information about the number of sectors which
is also the lowest unused block address and thus a suitable NWA.
This block address is stored in the Primary Volume Descriptor which is supposed
to be stored in block 16 (eventually relative to MSC1).
The bytes 0 to 5 of a PVD block are
0x01 'C' 'D' '0' '0' '1'
The sector count can then be read from byte 80 to 83
sectors= pvd[80] | (pvd[81] << 8) | (pvd[82] << 16) | (pvd[83] << 24);
(Ecma-119.pdf 8.4)
To support CD, DVD and BD media alike, it is advisable to round the NWA
to the next multiple of 32 (= 64 KiB).
So one can use 0 as MSC1 and prepare a new ISO session for the computed NWA.
After writing the session it is necessary to copy the PVD from session start
plus 16 to LBA 16 and to adjust it to its new location.
The minimal change would be to update the number of image sectors.
It is stored in both notations LSB and MSB:
for(i= 0; i < 4; i++)
pvd[87 - i]= pvd[80 + i]= (sectors >> (8 * i)) & 0xff;
cdrskin --grow_overwriteable_iso not only patches the sector fields of the
PVD block but also the blocks up to LBA 31 which begin with
0xff 'C' 'D' '0' '0' '1'
libisoburn submits 64 KiB data buffer to libisofs before image generation and
afterwards writes these 64 KiB as new superblock to LBA 0.
-------------------------------------------------------------------------------
ISO 9660 based TOC emulation on overwriteable media :
Above method of multi-session emulation yields a single session image after
each add-on session. No reliable session history can be read because the
sector size of the existing session gets overwritten by the new one.
A TOC with session history is nevertheless desirable with incremental backups
in order to access older backup states by mounting older superblocks at the
start addresses of older sessions.
All usual ISO 9660 formatter programs write a complete superblock to the
start of each session.
With a uniform NWA rounding rule it is possible to compute the address of
superblock N+1 as the NWA after session N. The only problem is N=1
because it gets overwritten by later sessions.
libisoburn preserves the information of session 1 by writing the first session
to LBA 32 rather than LBA 0. Afterwards it writes the overall superblock to
LBA 0 (up to 31).
So with all further add-on sessions the superblock at LBA 0 will enclose the
overall image, while the superblocks of the sessions form a chain beginning
at LBA 32. Each session superblock points to the next one by its sector count
rounded up to 32. The chain end is marked by the overall image size.
This chain gives the start addresses of sessions. The sector count minus start
address gives the size of a particular session. ECMA-119 explains how to
retrieve more info from the PVD (e.g. the volume id).

(mmc5r03c.pdf 4.5.3.5.2.2)
This structure is formatted onto blank media automatically as soon as the
first serious write attempt occurs.
(mmc5r03c.pdf 4.5.3.5)
Before such a write attempt, blank media may be explicitely formatted with
spares, which provide defect management.
(mmc5r03c.pdf 4.5.3.5.3)
Tracks get created from other tracks via RESERVE TRACK splitting.
(mmc5r03c.pdf 4.5.3.5.2.5)
On top of defect management there may be Pseudo-OverWrite SRM+POW, a costly
way to write several times to the same LBA. See below.
Fully sequential states are called SRM-POW.
(mmc5r03c.pdf 4.5.3.5.4)
Explicite formatting is done by 04h FORMAT UNIT. Its data payload consists
of a Format List Header and a Format Descriptor. It is advisable to set
the Immed bit and the FOV bit in header byte number 1. The descriptor should
be a copy of a descriptor from 23h READ FORMAT CAPACITIES but the size may be
adjusted within a certain range.
(mmc5r03c.pdf 6.5, 6.5.3.2, 6.5.3.3)
Format type 00h creates SRM layouts with a default number of spares (or
eventually RRM) chosen by the format sub-type:
00b = SRM with support for POW
01b = SRM without POW (but with some spares for defect management)
10b = (RRM)
(mmc5r03c.pdf 6.5.4.2.1.6)
Format type 32h uses the same sub-types but can allocate non-default
amounts of spares. Similar to BD-RE format 31h, three format descriptors are
offered: #1: default size, #2: maximum spare area, #3: minimal spare.
The size may be chosen within that range.
The sense behind the Type Dependent Parameters is obscure
to me. Best will be to set ISA_V and TDMA_V to 0.
(mmc5r03c.pdf 6.5.4.2.1.17)
-------------------------------------------------------------------------------
Writing a session in SRM:
The procedure and constraints for writing BD-R SRM-POW are very similar to
DVD+R. libburn flatly re-uses its DVD+R code except the Close Function for
finalizing a disc.
In short:
If all written sessions are closed, then there is exactly one NWA.
In the beginning there is an empty session and track. A new track can be
written either with pre-announced size (by RESERVE TRACK) or open-end by
simply starting to write to the NWA. When done the track gets closed by
close function 001b. Then either session or disc gets closed depending on
the Close Function used:
- Close Function 010b closes the session and keeps the media appendable
(same as with DVD+R)
- Close Function 110b finalizes the media and makes it read-only.
(differs from libburn DVD+R procedure which uses 101b)
-------------------------------------------------------------------------------
Pseudo-OverWrite POW: (no used yet by libburn)
This enhancement of SRM emulates overwriting of existing data blocks.
(mmc5r03c.pdf 4.5.3.5.4)
POW establishes a virtual vLBA space on top of the real address space rLBA.
All read and write commands deal with vLBA. It seems that track NWAs are
assumed to be identical in vLBA space and in rLBA space.
It is not clear whether one may write to vLBA blocks which are neither written
yet nor at one of the track NWAs. Probably not, or else one could make NWAs run
into vLBAs which are associated with older rLBAs.
Replacing invalidated blocks consumes addresses in rLBA space at the NWA of
some track. I.e. no spares are consumed by POW. Nevertheless it is costly by
a special map called Orphanage. It covers rLBA which have been consumed
by differing vLBAs. It never shrinks and can grow with each write to remapped
addresses.
To avoid heavy Orphanage growth it is advised to write mostly to vLBA which
still coincide with their rLBA. E.g. those addresses which have neither been
written as rLBA nor as vLBA yet. So one should begin the vLBA of new sessions
at the NWA of a sufficiently sized track.

Sound extraction for CD-DA burning from .WAV audio file format
Using information and text snippets
from https://ccrma.stanford.edu/courses/422/projects/WaveFormat/
in may 2013. The link is now dead. An apparent copy of the page
is 2017 at: http://soundfile.sapp.org/doc/WaveFormat/
from https://en.wikipedia.org/wiki/WAV
For libburnia-project.org by Thomas Schmitt <scdbackup@gmx.net>
December 2017
The WAVE file format is an application of the Microsoft RIFF container format
for multimedia files. A RIFF file consists of Chunks which contain Subchunks.
The Chunks form a linked list within the file, the Subchunks form a linked
list inside their Chunk.
All numbers are stored in little-endian byte order.
A .WAV file consists at least of one Chunk with id "RIFF", which contains
one Subchunk with id "fmt " and one with id "data":
Offset Size Name Description
0 4 ChunkID Contains the letters "RIFF"
4 4 ChunkSize The size of the rest of the chunk following
this field. I.e. the two fields ChunkID and
ChunkSize are not included in this count.
8 4 Format Contains the letters "WAVE"
The "fmt " subchunk describes the sound data's format:
Offset Size Name Description
0 4 Subchunk1ID Contains the letters "fmt "
4 4 Subchunk1Size The size of the rest of the Subchunk following
this field. I.e. Subchunk1ID and Subchunk1Size
are not included in this count.
8 2 AudioFormat PCM = 1 (i.e. Linear quantization)
Values other than 1 indicate some
form of compression.
10 2 NumChannels Mono = 1, Stereo = 2, etc.
12 4 SampleRate 8000, 44100, etc.
16 4 ByteRate == SampleRate * NumChannels * BitsPerSample/8
20 2 BlockAlign == NumChannels * BitsPerSample/8
The number of bytes for one sample including
all channels.
22 2 BitsPerSample 8 bits = 8, 16 bits = 16, etc.
More data may follow in this Subchunk if AudioFormat is not PCM.
The "data" subchunk contains the size of the data and the actual sound:
Offset Size Name Description
0 4 Subchunk2ID Contains the letters "data"
4 4 Subchunk2Size == NumSamples * NumChannels * BitsPerSample/8
The number of audio data bytes.
8 * Data The audio data bytes.
CD-DA prescribes these "fmt " parameters:
AudioFormat == 1
SampleRate == 44100
BitsPerSample == 16
NumChannels == 2 (stereo)
(little-endian byte order)
If matching parameters are given in the .WAV file, one can directly use the
data bytes of Subchunk "data" as payload for burning a CD-DA track.
Above simple form can be expanded by other Chunks or Subchunks of Chunk "RIFF".
A .wav file appeared which beared a Subchunk "LIST" inside Chunk "RIFF".
Wikipedia mentions Chunks "INFO", "CSET", "JUNK", "PAD ".
Therefore one should expect such Chunks before Chunk "RIFF" and Subchunks
other than "fmt " and "data" inside the "RIFF" Chunk.
Multiple Chunks "RIFF" and Subchunks "fmt " or "data" per file have not been
seen yet. They would make extraction more cumbersome.

/* Exploration ts B00214 :
ECMA-130, 22.3.6 "CRC field"
"This field contains the inverted parity bits. The CRC code word must be
divisible by the check polynomial. [...]
The generating polynomial shall be
G(x) = x^16 + x^12 + x^5 + 1
"
Also known as CRC-16-CCITT, CRC-CCITT
Used in libburn for raw write modes in sector.c.
There is also disabled code in read.c which would use it.
ts B11222:
The same algorithm is prescribed for CD-TEXT in MMC-3 Annex J.
"CRC Field consists of 2 bytes. Initiator system may use these bytes
to check errors in the Pack. The polynomial is x^16 + x^12 + x^5 + 1.
All bits shall be inverted."
libburn/cdtext.c uses a simple bit shifting function : crc_11021()
ts B20211:
Discussion why both are equivalent in respect to their result:
Both map the bits of the given bytes to a polynomial over the finite field
of two elements "GF(2)". If bytes 0 .. M are given, then bit n of byte m
is mapped to the coefficient of x exponent (n + ((M - m) * 8) + 16).
I.e. they translate the bits into a polynomial with the highest bit
becoming the coefficient of the highest power of x. Then this polynomial
is multiplied by (x exp 16).
The set of all such polynomials forms a commutative ring. Its addition
corresponds to bitwise exclusive or. Addition and subtraction are identical.
Multiplication with polynomials of only one single non-zero coefficient
corresponds to leftward bit shifting by the exponent of that coefficient.
The same rules apply as with elementary school arithmetics on integer
numbers, but with surprising results due to the finite nature of the
coefficient number space.
Note that multiplication is _not_ an iteration of addition here.
Function crc_11021() performs a division with residue by the euclidian
algorithm. I.e. it splits polynomial d into quotient q(d) and residue r(d)
in respect to the polynomial p = x exp 16 + x exp 12 + x exp 5 + x exp 0
d = p * q(d) + r(d)
where r(d) is of a polynomial degree lower than p, i.e. only x exp 15
or lower have non-zero coefficients.
The checksum crc(D) is derived by reverse mapping (r(d) * (x exp 16)).
I.e. by mapping the coefficient of (x exp n) to bit n of the 16 bit word
crc(D).
The function result is the bit-wise complement of crc(D).
Function crc_ccitt uses a table ccitt_table of r(d) values for the
polynomials d which represent the single byte values 0x00 to 0xff.
It computes r(d) by computing the residues of an iteratively expanded
polynomial. The expansion of the processed byte string A by the next byte B
from the input byte string happens by shifting the string 8 bits to the
left, and by oring B onto bits 0 to 7.
In the space of polynomials, the already processed polynomial "a" (image of
byte string A) gets expanded by polynomial b (the image of byte B) like this
a * X + b
where X is (x exp 8), i.e. the single coefficient polynomial of degree 8.
The following argumentation uses algebra with commutative, associative
and distributive laws.
Valid especially with polynomials is this rule:
(1): r(a + b) = r(a) + r(b)
because r(a) and r(b) are of degree lower than degree(p) and
degree(a + b) <= max(degree(a), degree(b))
Further valid are:
(2): r(a) = r(r(a))
(3): r(p * a) = 0
The residue of this expanded polynomial can be expressed by means of the
residue r(a) which is known from the previous iteration step, and the
residue r(b) which may be looked up in ccitt_table.
r(a * X + b)
= r(p * q(a) * X + r(a) * X + p * q(b) + r(b))
Applying rule (1):
= r(p * q(a) * X) + r(r(a) * X) + r(p * q(b)) + r(r(b))
Rule (3) and rule (2):
= r(r(a) * X) + r(b)
Be h(a) and l(a) chosen so that: r(a) = h(a) * X + l(a),
and l(a) has zero coefficients above (x exp 7), and h(a) * X has zero
coefficients below (x exp 8). (They correspond to the high and low byte
of the 16 bit word crc(A).)
So the previous statement can be written as:
= r(h(a) * X * X) + r(l(a) * X) + r(b)
Since the degree of l(a) is lower than 8, the degree of l(a) * X is lower
than 16. Thus it cannot be divisible by p which has degree 16.
So: r(l(a) * X) = l(a) * X
This yields
= l(a) * X + r(h(a) * X * X + b)
h(a) * X * X is the polynomial representation of the high byte of 16 bit
word crc(A).
So in the world of bit patterns the iteration step is:
crc(byte string A expanded by byte B)
= (low_byte(crc(A)) << 8) ^ crc(high_byte(crc(A)) ^ B)
And this is what function crc_ccitt() does, modulo swapping the exor
operants and the final bit inversion which is prescribed by ECMA-130
and MMC-3 Annex J.
The start value of the table driven byte shifting algorithm may be
different from the start value of an equivalent bit shifting algorithm.
This is because the final flushing by zero bits is already pre-computed
in the table. So the start value of the table driven algorithm must be
the CRC of the 0-polynomial under the start value of the bit shifting
algorithm.
This fact is not of much importance here, because the start value of
the bit shifter is 0x0000 which leads to CRC 0x0000 and thus to start
value 0x0000 with the table driven byte shifter.

ECMA-130, 14.3 "EDC field"
"The EDC field shall consist of 4 bytes recorded in positions 2064 to 2067.
The error detection code shall be a 32-bit CRC applied on bytes 0 to 2063.
The least significant bit of a data byte is used first. The EDC codeword
must be divisible by the check polynomial:
P(x) = (x^16 + x^15 + x^2 + 1) . (x^16 + x^2 + x + 1)

ts B20211:
Discussion why function crc_32() implements above prescription of ECMA-130.
See end of this file for the ofunction inherited with libburn-0.2.
The mentioned polynomial product
(x^16 + x^15 + x^2 + 1) . (x^16 + x^2 + x + 1)
yields this sum of x exponents
32 31 18 16
18 17 4 2
17 16 3 1
16 15 2 0
======================================
32 31 16 15 4 3 1 0
(The number of x^18 and x^17 is divisible by two and thus 0 in GF(2).)
This yields as 33 bit number:
0x18001801b
If above prescription gets implemented straight forward by function
crc_18001801b(), then its results match the ones of crc_32() with all test
strings which i could invent.
The function consists of a conventional polynomial division with reverse
input order of bits per byte.
Further it swaps the bits in the resulting 32 bit word. That is because
sector.c:sector_headers writes the 4 bytes of crc_32() as little endian.
The ECMA-130 prescription rather demands big endianness and bit swapping
towards the normal bit order in bytes:
"The EDC field shall consist of 4 bytes recorded in positions 2064 to 2067.
[...]
The least significant parity bit (x^0) is stored in the most
significant bit position of byte 2067."

Above discussion why crc_ccitt() and crc_11021() yield identical results
can be changed from 16 bit to 32 bit by chosing h(a) and l(a) so that:
r(a) = h(a) * X * X * X + l(a)
h(a) corresponds to the highest byte of crc(A), whereas l(a) corresponds
to the lower three bytes of crc(A).
This yields
r(a * X + b)
= l(a) * X + r(h(a) * X * X * X * X + b)
h(a) * X * X * X * X is the polynomial representation of the high byte of
32 bit word crc(A).
So in the world of bit patterns we have:
crc(byte string A expanded by byte B)
= (lowest_three_bytes(crc(A)) << 8) ^ crc(high_byte(crc(A)) ^ B)
Regrettably this does not yet account for the byte-internal mirroring of
bits during the conversion from bit pattern to polynomial, and during
conversion from polynomial residue to bit pattern.
Be rfl8(D) the result of byte-internal mirroring of bit pattern D,
and mirr8(d) its corresponding polynom.
Be now h(a) and l(a) chosen so that: r(mirr8(a)) = h(a) * X * X * X + l(a)
This corresponds to highest byte and lower three bytes of crc(A).
r(mirr8(a) * X + mirr8(b))
= r(h(a) * X * X * X * X) + r(l(a) * X) + r(mirr8(b))
= l(a)) * X + r(h(a) * X * X * X * X + mirr8(b))
The corresponding bit pattern operation is
crc(mirrored byte string A expanded by mirrored byte B)
= (lowest_three_bytes(crc(A)) << 8) ^ crc(high_byte(crc(A)) ^ rfl8(B))
This demands a final result mirroring to meet the ECMA-130 prescription.
rfl8() can be implemented as lookup table.
The start value of the bit shifting iteration is 0x00000000, which leads
to the same start value for the table driven byte shifting.
The following function crc32_by_tab() yields the same results as functions
crc_18001801b() and crc_32():

Above function yields sufficient performance, nevertheless the old function
crc_32() (see below) is faster by avoiding the additional mirror table
lookup.
A test with 10 times 650 MB on 3000 MHz amd64:
crc_18001801b : 187 s
crc32_by_tab : 27 s
crc_32 : 16 s
So how does crc_32() avoid the application of bit mirroring to B ?.
Inherited crc_32() performs
crc = crc32_table[(crc ^ *data++) & 0xffL] ^ (crc >> 8);
Above function crc32_by_tab() would be
crc = crc_tab[(crc >> 24) ^ mirr_tab[*data++]] ^ (crc << 8);
The shortcut does not change the polynomial representation of the algorithm
or the mapping from and to bit patterns. It only mirrors the bit direction
in the bytes and in the 32-bit words which are involved in the bit pattern
computation. This affects input (which is desired), intermediate state
(which is as good as unmirrored), and final output (which would be slightly
undesirable if libburn could not use the mirrored result anyway).
Instead of the high byte (crc >> 24), the abbreviated algorithm uses
the low byte of the mirrored intermediate checksum (crc & 0xffL).
Instead of shifting the other three intermediate bytes to the left
(crc << 8), the abbreviated algorithm shifts them to the right (crc >> 8).
In both cases they overwrite the single byte that was used for computing
the table index.
The byte indexed table of CRC values needs to hold mirrored 32 bit values.
The byte index [(crc ^ *data++) & 0xffL] would need to be mirrored, which
would eat up the gain of not mirroring the input bytes. But this mirroring
can be pre-computed into the table by exchanging each value with the value
of its mirrored index.
So this relation exists between the CRC table crc_tab[] of crc32_by_tab()
and the table crc32_table[] of the abbreviated algorithm crc_32():
crc_tab[i] == rfl32(crc32_table[rfl8(i)])
for i={0..255}.
I compared the generated table in crc32_by_tab() by this test
for (i = 0; i < 256; i++) {
if (rfl32(crc_tab[rfl8(i)]) != crc32_table[i] ||
crc_tab[i] != rfl32(crc32_table[rfl8(i)])) {
printf("DEVIATION : i = %d\n", i);
exit(1);
}
}
No screaming abort happened.

This code module implements the production of RSPC parity bytes (P- and Q-
parity) and the scrambling of raw CD-ROM sectors as specified in ECMA-130:
http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-130.pdf
The following statements about Galois Fields have been learned mostly from
http://www.cs.utk.edu/~plank/plank/papers/CS-96-332.pdf
by James S. Plank after an e-mail exchange with Norbert Preining.
The output has been compared with the output of the old code of libburn
which was labeled "borrowed HEAVILY from cdrdao" and claimed by Joerg
Schilling to stem from code by Heiko Eissfeldt.
-------------------------------------------------------------------------
Note: In this text, "^" denotes exponentiation and not the binary exor
operation. Confusingly in the C code "^" is said exor.
Note: This is not C1, C2 which is rather mentioned in ECMA-130 Annex C and
always performed inside the drive.
-------------------------------------------------------------------------
RSPC , P- and Q-Parity
ECMA-130 Annex A prescribes to compute the parity bytes for P-columns and
Q-diagonals by RSPC based on a Galois Field GF(2^8) with enumerating
polynomials x^8+x^4+x^3+x^2+1 (i.e. 0x11d) and x^1 (i.e. 0x02).
Bytes 12 to 2075 of a audio-sized sector get ordered in two byte words
as 24 rows and 43 columns. Then this matrix is split into a LSB matrix
and a MSB matrix of the same layout. Parity bytes are to be computed
from these 8-bit values.
2 P-bytes cover each column of 24 bytes. They get appended to the matrix
as rows 24 and 25.
2 Q-bytes cover each the 26 diagonals of the extended matrix.
Both parity byte pairs have to be computed so that extended rows or
diagonals match this linear equation:
H x V = (0,0)
H is a 2-row matrix of size n matching the length of the V ectors
[ 1 1 ... 1 1 ]
[ x^(n-1) x^(n-2) x^1 1 ]
Vp represents a P-row. It is a byte vector consisting of row bytes at
position 0 to 23 and the two parity bytes which shall be determined
at position 24 and 25. So Hp has 26 columns.
Vq represents a Q-diagonal. It is a byte vector consisting of diagonal
bytes at position 0 to 42 and the two parity bytes at position 43 and 44.
So Hq has 45 columns. The Q-diagonals cover P-parity bytes.
By applying some high school algebra one gets the parity bytes b0, b1 of
vector V = (n_payload_bytes, b0 , b1) as
b0 = ( H[n] * SUM(n_payload_bytes) - H[0..(n-1)] x n_payload_bytes )
/ (H[n+1] - H[n])
b1 = - SUM(n_payload_bytes) - b0
H[i] is the i-the element of the second row of matrix H. E.g. H[0] = x^(n-1)
The result has to be computed by Galois field arithmetics. See below.
The P-parity bytes of each column get reunited as LSB and MSB of two words.
word1 gets written to positions 1032 to 1074, word0 to 1075 to 1117.
The Q-parity bytes of each diagonal get reunited too. word1 goes to 1118
to 1143, word0 to 1144 to 1169.
>>> I do not read this swap of word1 and word0 from ECMA-130 Annex A.
>>> But the new output matches the old output only if it is done that way.
>>> See correctness reservation below.
Algebra on Galois fields is the same as on Rational Numbers.
But arithmetics on its polynomials differ from usual integer arithmetics
on binary numbers.
Addition and subtraction are identical with the binary exor operator.
Multiplication and division would demand polynomial division, e.g. by the
euclidean algorithm. The computing path over logarithms and powers follows
algebra and reduces the arithmetic task to table lookups, additions
modulo 255, and exor operations. Note that the logarithms are natural
numbers, not polynomials. They get added or subtracted by the usual addition
(not by exor) and their polynomial power depends on their value modulo 255.
Needed are a logarithm table and a power table (or inverse logarithm table)
for Galois Field GF(2^8) which will serve to perform the peculiar
multiplication and division operation of Galois fields.
The power table is simply an enumeration of x^n accorting to
GF-multiplication. It also serves as second line of matrix H for the parity
equations:
Hp[i] = gfpow[25-i] , i out of {0,..,25}
Hq[i] = gfpow[44-i] , i out of {0,..,44}
The logarithm table is the inverse permutation of the power table.
Some simplifications apply to the implementation:
In the world of Galois fields there is no difference between - and +.
The term (H[n+1] - H[n]) is constant: 3.
-------------------------------------------------------------------------
Scrambling
ECMA-130 Annex B prescribes to exor the byte stream of an audio-sized sector
with a sequence of pseudo random bytes. It mentions polynomial x^15+x+1 and
a 15-bit register.
It shows a diagram of a Feedback Shift Register with 16 bit boxes, though.
Comparing this with explanations in
http://www.newwaveinstruments.com/resources/articles/m_sequence_linear_feedback_shift_register_lfsr.htm
one can recognize the diagram as a Fibonacci Implementation. But there seems
really to be one bit box too many.
The difference of both lengths is expressed in function next_bit() by
the constants 0x3fff,0x4000 for 15 bit versus 0x7fff,0x8000 for 16 bits.
Comparing the output of both alternatives with the old scrambler output
lets 15 bit win for now.
So the prescription is to start with 15 bit value 1, to use the lowest bit
as output, to shift the bits down by one, to exor the output bit with the
next lowest bit, and to put that exor result into bit 14 of the register.
-------------------------------------------------------------------------
Correctness Reservation
In both cases, parity and scrambling, the goal for now is to replicate the
output of the dismissed old lec.c by output which is based on published
specs and own implementation code. Whether they comply to ECMA-130 is a
different question which can only be answered by real test cases for
raw CD recording.
Of course this implementation will be corrected so that it really complies
to ECMA-130 as soon as evidence emerges that it does not yet.

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_id_string() returns an id string of the SCSI transport adapter.
It may be called before initialization but then may
return only a preliminary id.
sg_initialize() performs global initialization of the SCSI transport
adapter and eventually needed operating system
facilities. Checks for compatibility of supporting
software components.
sg_shutdown() performs global finalizations and releases globally
acquired resources.
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_dispose_drive() finalizes adapter specifics of struct burn_drive
on destruction. Releases resources which were acquired
underneath scsi_enumerate_drives().
sg_drive_is_open() tells whether libburn has the given drive in use.
sg_drive_is_open() tells wether libburn has the given drive in use.

sg_obtain_scsi_adr() tries to obtain SCSI address parameters.

burn_os_stdio_capacity() estimates the emulated media space of stdio-drives.
burn_os_open_track_src() opens a disk file in a way that offers best
throughput with file reading and/or SCSI write command
transmission.
burn_os_alloc_buffer() allocates a memory area that is suitable for file
descriptors issued by burn_os_open_track_src().

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: NetBSD 6, ioctl SCIOCCOMMAND
OpenBSD 5.9, ioctl SCIOCCOMMAND
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_id_string() returns an id string of the SCSI transport adapter.
It may be called before initialization but then may
return only a preliminary id.
sg_initialize() performs global initialization of the SCSI transport
adapter and eventually needed operating system
facilities. Checks for compatibility of supporting
software components.
sg_shutdown() performs global finalizations and releases globally
acquired resources.
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_dispose_drive() finalizes adapter specifics of struct burn_drive
on destruction. Releases resources which were acquired
underneath scsi_enumerate_drives().
sg_drive_is_open() tells whether 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 whether the command succeeded or shall
be retried or finally failed.
sg_obtain_scsi_adr() tries to obtain SCSI address parameters.
burn_os_is_2k_seekrw() tells whether the given path leads to a file object
that can be used in 2 kB granularity by lseek(2),
read(2), and possibly write(2) if not read-only..
E.g. a USB stick or a hard disk.
burn_os_stdio_capacity() estimates the emulated media space of stdio-drives.
burn_os_open_track_src() opens a disk file in a way that offers best
throughput with file reading and/or SCSI write command
transmission.
burn_os_alloc_buffer() allocates a memory area that is suitable for file
descriptors issued by burn_os_open_track_src().
The buffer size may be rounded up for alignment
reasons.
burn_os_free_buffer() delete a buffer obtained by burn_os_alloc_buffer().
Porting hints are marked by the text "PORTING:".

/** Overview
libburner is a minimal demo application for the library libburn as provided
on http://libburnia-project.org . It can list the available devices, can
blank a CD-RW or DVD-RW, can format DVD-RW and BD, can burn to CD-R,
CD-RW, DVD-R, DVD+R, DVD+R/DL, DVD+RW, DVD-RW, DVD-RAM, BD-R, BD-RE.
Not supported yet: DVD-R/DL.
blank a CD-RW or DVD-RW, can format DVD-RW and BD-RE, can burn to CD-R,
CD-RW, DVD-R, DVD+R, DVD+R/DL, DVD+RW, DVD-RW, DVD-RAM, BD-RE.
Not supported yet: DVD-R/DL, BD-R.
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.
There is another demo program, test/telltoc.c, which inspects drive, media
state, and media contents.
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("libburner : ", NULL, 0x0)
as it is done in main() at the end of this file.
Then you acquire a drive in an appropriate way conforming to the API. The two
main approaches are shown here in application functions:
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 acquired drive you can blank a CD-RW or DVD-RW as shown in
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)
or an unused BD to default size with spare blocks
libburner_format()
With the acquired drive you can burn to CD, DVD, BD. See
or an unused BD-RE to default size
libburner_format_owrt()
With the aquired drive you can burn to CD or DVD
libburner_payload()
These three functions switch temporarily to a non-fatal signal handler
while they are waiting for the drive to become idle again:
burn_set_signal_handling("libburner : ", NULL, 0x30)
After the waiting loop ended, they check for eventual abort events by
burn_is_aborting(0)
The 0x30 handler will eventually execute
burn_abort()
but not wait for the drive to become idle and not call exit().
This is needed because the worker threads might block as long as the signal
handler has not returned. The 0x0 handler would wait for them to finish.
Take this into respect when implementing own signal handlers.
When everything is done, main() releases the drive and shuts down libburn:
burn_drive_release();
burn_finish()
Applications must use 64 bit off_t. E.g. by defining
#define _LARGEFILE_SOURCE
#define _FILE_OFFSET_BITS 64
or take special precautions to interface with the library by 64 bit integers
where libburn/libburn.h prescribes off_t.
This program gets fed with appropriate settings externally by libburn's
autotools generated build system.

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
