cdrskin-1.4.6

[musher0]

Hello all.

I hope you are well.

I have compiled dynamically (i.e. it has no static libs) cdrskin-1.4.6, which
is the latest stable version as of this writing.

Please download it from here:
https://my.pcloud.com/publink/show?code ... NONSvf2fqk

I have compiled it on the Puduan-6.0 Pup, which means it should work on any
Pup with a glibc of 2.17 or higher.

To find out which version of the C library you have on your Puppy, please
open a terminal and type:

Code: Select all

ldd --version

• -=> If you get a number lower than 2.17 this version will NOT work on
  your Pup.
  -=> You may then want to try out this older version of cdrskin that has
  been made available by plinej here, back in July 2011.

You'll find more info on cdrskin here. Cdrskin was written by Mario Danic and
Thomas Schmitt.

I find cdrskin most useful for re-formatting and re-inscribing small DVDs
(mini-DVD's of 1.5 Gb) when PBurn cannot (or refuses to?) do the job.

Enjoy!

Hello again people.

I've included the full docs in the pet archive under
/usr/share/doc/cdrskin-1.4.6/cdrskin-Usage.txt (q.v.), but here is an
excerpt with examples that you can use as a convenient quick reference:

cdrskin usage

The user of cdrskin needs rw-permission for the CD burner device.
A list of rw-accessible drives can be obtained by

cdrskin --devices

CD devices which offer no rw-permission are invisible to normal users.
The superuser should be able to see any usable drive and then set the
permissions as needed. If this hangs then there is a drive with
unexpected problems (locked, busy, broken, whatever). You might have to
guess the address of your (non-broken) burner by other means, then.
On Linux 2.4 this would be some /dev/sgN and on 2.6. some /dev/srM or /dev/hdX.

The output of cdrskin --devices might look like

0 dev='/dev/sr0' rwrwr- : '_NEC' 'DVD_RW ND-4570A'
1 dev='/dev/sr1' rwrw-- : 'HL-DT-ST' 'DVDRAM GSA-4082B'

Usage examples

For options and recordable media classes see
man 1 cdrskin

Get an overview of cdrecord style addresses of available devices
cdrskin -scanbus
cdrskin dev=ATA -scanbus
cdrskin --devices

Adresses reported with dev=ATA need prefix "ATA:". Address examples:

cdrskin dev=0,1,0 -checkdrive

Obtain some info about the drive and the inserted media
cdrskin dev=0,1,0 -atip -v -minfo

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=0,1,0 blank=format_overwrite

cdrskin -v dev=/dev/sr0 blank=deformat_sequential

Burn image file my_image.iso to media
cdrskin -v dev=0,1,0 speed=12 fs=8m driveropts=burnfree padsize=300k \

Write multi-session to the same CD , DVD-R[W] or DVD+R[/DL]
cdrskin dev=/dev/hdc padsize=300k -multi 1.iso

Get multi-session info for option -C of program mkisofs:
c_values=$(cdrskin dev=/dev/hdc -msinfo 2>/dev/null)
mkisofs ... -C "$c_values" ...

Burn a compressed afio archive to media on-the-fly
find . | afio -oZ - | cdrskin -v dev=0,1,0 fs=32m speed=8 \
driveropts=burnfree padsize=300k -

Burn 6 audio tracks from files with different formats to CD (not to any DVD).
Anything except .wav or .au files has to be converted into raw format first.
See below "Audio CD" for specifications.
ogg123 -d raw -f track01.cd /path/to/track1.ogg
oggdec -R -o track02.cd /path/to/track2.ogg
lame --decode -t /path/to/track3.mp3 track03.cd
madplay -o raw:track04.cd /path/to/track4.mp3
mppdec --raw-le /path/to/track5.mpc track05.cd

cdrskin -v dev=0,1,0 blank=fast -eject speed=48 -sao \
-audio -swab track0[1-5].cd /path/to/track6.wav

Extract audio tracks and CD-TEXT from CD into directory /home/me/my_cd:
mkdir /home/me/my_cd
cdrskin -v dev=/dev/sr0 extract_audio_to=/home/me/my_cd \
cdtext_to_v07t=/home/me/my_cd/cdtext.v07t

Audio CD

Lorenzo Taylor enabled option -audio in cdrskin (thanks !) and reports neat
results with audio data files which are :
headerless PCM (i.e. uncompressed)
44100 Hz sampling rate
16 bits per sample
stereo (2 channels)
little-endian byte order with option -swab, or big-endian without -swab

Files with name extension .wav get examined wether they are in Microsoft WAVE
format with above parameters and eventually get extracted by cdrskin itself.
In the same way files with name extension .au get examined wether they are
in SUN's audio format. For both formats, track format -audio and eventual
endianness option -swab are enabled automatically.

Any other formats are to be converted to format .wav with above parameters
or to be extracted as raw CD track data by commands like those given above
under "Usage examples". Those raw files need option -audio and in most cases
option -swab to mark them as little-endian/Intel/LSB-first 16-bit data.
Incorrect endianness setting results in random noise on CD.

I myself am not into audio. So libburn-hackers@pykix.org might be the
best address for suggestions, requests and bug reports.

DVD-RW , DVD-R , DVD-R DL

DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state
"Sequential Recording". DVD-R are always in sequential state. DVD-R DL are
always sequential and incapable of multi-session.

"Sequential" is the state of unused media and of media previously blanked
or written by cdrecord. dvd+rw-format -blank can also achieve this state.
The according cdrskin option is blank=deformat_sequential .
If "Incremental Streaming" is available, then sequential media are capable
of multi-session like CD-R[W]. (But not capable of -audio recording.)
This means they need option -multi to stay appendable, need to be blanked
to be writeable from start, return useable info with -toc and -msinfo,
eventually perform appending automatically.
Without Incremental Streaming offered by the drive, only write mode DAO is
available with sequential DVD-R[W]. It only works with blank media, allows only
one single track, no -multi, and demands a fixely predicted track size.
(growisofs uses it with DVD-R[W] if option -dvd-compat is given.)

Overwriteable DVD-RW behave much like DVD+RW. "Restricted" refers only to the
granularity of random access and block size which have always to be aligned to
full 32 kB. Sequential DVD-RW are converted into overwriteable DVD-RW by
cdrskin dev=... -v blank=format_overwrite
(Command dvd+rw-format -force can achieve Restricted Overwrite, too.)

Formatting or first use of freshly formatted DVD-RW can produce unusual noises
from the drive and last several minutes. Depending on mutual compatibility of
drive and media, formatting can yield unusable media. It seems that those die
too on blanking by cdrecord, dvd+rw-format or cdrskin. Perils of DVD-RW.

There are three DVD-RW formatting variants with cdrskin currently:

blank=format_overwrite uses "DVD-RW Quick" formatting (MMC-type 15h)
and writes a first session of 128 MiB. This leads to media which are expandable
and random addressable by cdrskin.

blank=format_overwrite_quickest uses "DVD-RW Quick" formatting (type 15h) too,
but leaves the media in "intermediate" state. In the first session of writing
one may only write sequentially to such a DVD. After that, it gets random
addressable by cdrskin. DVD-ROM drives might show ill behavior with them.

blank=format_overwrite_full uses preferrably "Full Format" (type 00h).
This formatting lasts as long as writing a full DVD. It includes writing of
lead-out which is said to be good for DVD ROM compatibility.

De-formatting options are available to make overwriteable DVD-RW sequential:

blank=deformat_sequential performs thorough blanking of all states of DVD-RW.
blank=all and blank=fast perform the same thorough blanking, but refuse to do
this with overwriteable DVD-RW, thus preserving their formatting. The specs
allow minimal blanking but the resulting media on my drives offer no
Incremental Streaming afterwards. So blank=fast will do full blanking.

blank=deformat_sequential_quickest is faster but might yield DAO-only media.


DVD+R , DVD+R DL , BD-R

From the view of cdrskin they behave much like DVD-R. Each track gets wrapped
into an own session, though.

DVD+R DL appear as extra large DVD+R. cdrskin does not allow to set the address
of the layer break where a reading drive might show some delay while switching
between both media layers.

BD-R are sold unformatted blank. If used without initial formatting then the
drive is supposed to format them to maximum payload size with no Defect
Management (see also above with BD-RE).
If Defect Management is desired then BD-R need to be formatted before the
first attempt to write a session to them.
blank=format_if_needed will detect the situation and eventually apply
default sized Defect Management formatting.
blank=format_defectmgt_* will apply non-default parameters to formatting.

IHTH.
