TAO. -I have the hope that Joerg feels more flattered than annoyed by cdrskin. - - - Drive Addressing - -Drives get addressed either via their cdrecord-style addresses as listed -with option -scanbus (see below "Pseudo-SCSI Adresses") or via the paths -of device files. -Not only device files listed by --devices may be used but also device files -which via their major,minor numbers point to the same device driver as -a listed device file. - -Helpful with Linux kernel 2.4 is a special SCSI feature: -It is possible to address a scsi(-emulated) drive via associated device files -which are not listed by option --devices but point to the same SCSI addresses -as listed device files. This addressing via e.g. /dev/sr0 or /dev/scd1 is -compatible with generic read programs like dd and with write program growisofs. - - Pseudo-SCSI Adresses - -cdrecord and cdrskin share the syntax of SCSI addresses but not necessarily -the meaning of the components. A cdrecord-style address for cdrskin - [prefix:]scsibus,target,lun -can be interpreted in two different modes. - -Standard mode tries to be compatible to original cdrecord. This should be true -with (emulated) SCSI where the /dev/sgN with is looked up with matching -scsibus,target,lun as given by the operating system. -With dev=ATA: or dev=ATAPI: the translation to /dev/hdX is purely literal -but matches the cdrecord addresses on all systems tested so far: - X = 'a' + 2 * scsibus + target -where target only may have the values 0 or 1. - -In this mode, option -scanbus will list only SCSI devices unless option -dev=ATA or dev=ATAPI are given, which will suppress SCSI devices and only -show IDE drives (i.e. /dev/hdX without ide-scsi emulation). - - -In mode --old_pseudo_scsi_adr there is a scsibus,target,lun representation -which has nothing to do with SCSI and thus is not compatible to cdrecord. -Each number triple corresponds either to a device file address or to a -libburn drive number. -Component "scsibus" indicates the translation method. Defined busses are: - 0 target is the libburn drivenumber as listed with --devices - 1 associated to device file /dev/sgN , target chooses N - 2 associated to device file /dev/hdX , target 0='a', 1='b' ..., 25='z' - -So "1,1,0" is /dev/sg1, "2,3,0" is /dev/hdd, "0,2,0" is libburn drive #2 at -some unspecified device file. -This scheme shall help to keep cdrecord-style addresses stable and exchangeable -between users without excluding drives with unexpected device addresses. -The numbering on bus 0 is prone to arbitrary changes caused by changes in -drive accessability. -Further busses may emerge as libburn evolves. "prefix" and "lun" may get -a meaning. To stay upward compatible, use addresses as printed by -scanbus. - - User Defined Device Address Translation - -Some programs or users have their own ideas about the address of their burner. -K3b 0.10 for example derives cdrecord addresses by own examination of the -devices and not by calling cdrecord -scanbus. -Standard mode will hopefully be fully compatible with their ideas. - -Old frontends which do not know dev=ATA or dev=ATAPI and which do ask their -"cdrecord" via -scanbus may be well served with option --old_pseudo_scsi_adr . - -To direct any remaining stubborn callers to the appropriate drives, cdrskin -allows to define device address aliases. Like - cdrskin dev_translation=+1,0,0+/dev/sg1 \ - dev_translation=+ATA:1,0,0+/dev/sg1 \ - dev_translation=-"cd+dvd"-0,1,0 \ - ... -Any of the addresses dev=1,0,0, dev=ATA:1,0,0, dev=cd+dvd will be mapped to -/dev/sg1 resp. to 0,1,0. -The first character after "dev_translation=" defines the character which -separates the two parts of the translation pair. (Above: "+" and "-".) - -In K3b 0.10 it is possible to employ alternative writer programs by setting -their full path (e.g. /usr/bin/cdrskin) in menu - Settings:Configure K3b...:Programs:Search Path -and to make them default in menu - Settings:Configure K3b...:Programs:Programs: -A suitable setting for "cdrecord" in menu - Settings:Configure K3b...:Programs:User Parameters -would then probably be - -v dev_translation=+1,0,0+/dev/sg1 -You will learn from button "Show Debugging Output" after a failed burn run -what cdrecord command was used with what address "dev=...". This address "..." -will be the right one to replace "1,0,0" in above example. - - - Startup Files - -If not --no_rc is the first argument then cdrskin attempts on startup to read -arguments from the following three files: - /etc/defaults/cdrskin - /etc/opt/cdrskin/rc - $HOME/.cdrskinrc -The files are read in the sequence given above. -Each readable line is treated as one single argument. No extra blanks. -A first character '#' marks a comment, empty lines are ignored. - -Example content of a startup file: -# This is the default device -dev=0,1,0 -# To accomodate to eventual remnant cdrskin-0.2.2 addresses -dev_translation=+1,0,0+0,1,0 - -# Some more options ---fifo_start_empty -fs=16m - - - 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.

Therefore this explanation: - -On start it restricts the library to a single drive if it already knows the -persistent address by option dev= . This is done with a combination of -burn_drive_add_whitelist() and burn_drive_scan(). Not compliant to the -literal strong urge but in fact exactly fulfilling the reason for that -urge in the API: any scanned drive might be opened exclusively after -burn_drive_scan(). It is kernel dependent wether this behavior is on, off -or switchable. The sysdamin will want it on - but only for one drive. - -So with dev=... cdrskin complies to the spirit of the strong urge. -Without dev=... it has to leave out the whitelist in order to enable bus -scanning and implicit drive address 0. A tradition of 9 months shall not -be broken. So burns without dev= will stay possible - but harmless only -on single drive systems. - -Burns without dev= resp. with dev=number are harmless on multi-drive systems. - -This is because Cdrskin_grab_drive() either drops the unwanted drives or -it enforces a restart of the library with the desired drive's persistent -address. This restart then really uses the strongly urged function -burn_drive_scan_and_grab(). -Thus, cdrskin complies with the new spirit of API by closing down libburn -or by dropping unused drives as soon as the persistent drive address is -known and the drive is to be used with a long running operation. To my -knowlege all long running operations in cdrskin need a grabbed drive. - -This spaghetti approach seems necessary to keep small the impact of new API -urge on cdrskin's stability. cdrskin suffers from having donated the body -parts which have been transplanted to libburn in order to create - burn_drive_scan_and_grab() . The desired sysadmin friendlyness was already -achieved by most cdrskin runs.

Limited cdrecord compatibility wrapper for libburn

-
- -

-

Purpose:

-
    -
  • Burns preformatted data to CD-R or CD-RW
    • -
-

-

- -

- -

-

Hardware requirements:

-A CD recorder suitable for -libburn.pykix.org -(SCSI or IDE/ATAPI writers compliant to mmc standard). -
-

- -

-

Software requirements :

-
-
Linux kernel 2.4 or higher
-
With kernel 2.4 the drive has to be under ide-scsi emulation.
-
With kernel 2.6 the drive should not be under ide-scsi.
-
libpthread
-
is supposed to be a standard system component.
-
-

- -

-

-GPL software included:
-

-
-
libburn-0.2.3 stabilized SVN snapshot
-
(by Derek Foreman, Ben Jansens, and team of libburn.pykix.org)
-
transfers data to CD
-
-

- -

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

- -
- -

-

Special features:

-
    -
  • Source code is independent of -cdrecord -
    • -
-

- -

-

Commands:

-
-
The goal is to provide some of cdrecord's options in a compatible way. -This has been achieved quite sufficiently for the needs of backup tool -scdbackup -and for data CD projects of K3b -(see examples). -Suitability for audio CD frontends has been improved much and is now being -evaluated.
-Further enhancements depend on people who can describe and discuss their -wishes as well as on the development of libburn.
-

-
Get an overview of drives:
-
$ cdrskin -scanbus
-
$ cdrskin dev=ATA -scanbus
-
$ cdrskin --devices
-
Get info about a particular drive or loaded media:
-
$ cdrskin dev=0,1,0 -checkdrive
-
$ cdrskin dev=ATA:1,0,0 -atip
-
$ cdrskin dev=/dev/hdc -toc
-
Make used CD-RW writable again:
-
$ cdrskin -v dev=/dev/sg1 blank=all -eject
-
$ cdrskin -v dev=/dev/dvd blank=fast -eject
-
Write ISO-9660 filesystem image:
-
$ cdrskin -v dev=/dev/hdc speed=12 fs=8m driveropts=burnfree -sao -eject padsize=300k my_image.iso
-
Write compressed afio archive on-the-fly via cdrskin-0.2.4 :
-
$ find . | afio -oZ - | cdrskin -v dev=0,1,0 fs=32m speed=8 driveropts=burnfree padsize=300k -sao tsize=650m -
-
Write compressed afio archive on-the-fly via cdrskin-0.2.5 :
-
$ find . | afio -oZ - | cdrskin -v dev=0,1,0 fs=32m speed=8 driveropts=burnfree padsize=300k -tao -
-
Write audio tracks:
-
$ cdrskin -v dev=ATA:1,0,0 speed=48 driveropts=burnfree -sao track1.wav track2.au -audio -swab track3.raw -
-
-
cdrskin -help
-
reports the cdrecord compatible options
-
cdrskin --help
-
reports the non-cdrecord options
-
man cdrecord
-
documents the standard for which cdrskin is striving. -Do not bother Joerg Schilling with any cdrskin problems. -(Be cursed if you install cdrskin as "cdrecord" without clearly forwarding - this "don't bother Joerg" demand.) -
-
-

- -

-

Known deficiencies:

-
    -
    -
  • -Burns only a single closed session. No -multi option yet. -Note: Development version 0.2.5 offers multi-session now. See below. -
    • -
  • -No TAO mode in cdrskin-0.2.4 and therefore no writing on-the-fly without -a predefined source size.
    -Note: Development version 0.2.5 offers TAO now. See below. -
    • -
  • -cdrskin -scanbus or --devices hangs for quite a while if there is -a CD drive which does not work properly (e.g. because it has individual -problems with DMA). -So if the superuser gets no result with cdrskin --devices then one should -disable DMA with the problematic CD drives -(like: hdparm -d0 /dev/hdd ) -and try again.
    -In severe cases it might be necessary to guess the device name /dev/sgN resp. -/dev/hdX of the non-ill burner if it cannot be found otherwise among its -ill peers. Alternatively one can guess the address of the ill device, remove -rw-permissions and retry the bus scan as non-superuser. -

Download as source code (see README):
-
cdrskin-0.2.4.pl01.tar.gz -(510 KB). -
-
-The "stable" cdrskin tarballs are source code identical with "stable" -libburn releases or with "stabilized" libburn SVN snapshots. They get -produced via a different procedure, though.
-cdrskin is part of libburn - full libburn is provided with cdrskin releases. -

-
Download as single x86 binaries (untar and move to /usr/bin/cdrskin):
-
-cdrskin_0.2.4.pl01-x86-suse9_0.tar.gz, (60 KB), -
-
runs on SuSE 9.0 (2.4.21) , RIP-14.4 (2.6.14) , - Gentoo (2.6.15 x86_64 Athlon).
-

-Enhancements towards previous stable version cdrskin-0.2.2: -

    -
  • cdrecord compatibility with drive addresses of form [ATA:]Bus,Target,Lun. -
    (use option --old_pseudo_scsi_adr to get back the incompatible - Bus,Traget,Lun addressing of version 0.2.2) -
    • -
  • Drives adressable via links and device siblings (/dev/cdrom , /dev/scd0). -
    • -
  • Automatic -audio extraction with .wav files and .au files. -
    • -
  • Bug fix about failure to eject.
    • -
  • Comments and empty lines allowed in startup files.
    • -
  • Options -scanbus and --devices print SORRY messages about busy drives. -
    • -
  • Drive buffer fill indicator reports realistic percentage numbers.
    • -
  • Option -toc is supported, drive firmware revision gets displayed.
    • -
-

Development snapshot, version 0.2.5 :

-
Enhancements towards stable version 0.2.4: -
    -
  • Option -tao is fully enabled. - With single track or with undefined size from standard input, - default is -tao. With other multi-track sessions, default is -sao. - (The latter is an intentional deviation from cdrecord defaults.) -
    • -
  • Status report during blank, preparation and finalization improved.
    • -
  • Bug fixed: Trailing trash appended to .wav files caused error message - and, if exceeding fifo size, could even stall a burn. - (Workaround: disable fifo by fs=0)
    • -
  • Bug fixed: False speed with first pacifier cycle. Potential program - abort by floating point exception (NaN).
    • -
  • multi-session CDs: -multi, -msinfo, - writing to appendable CDs (for now restricted to write mode TAO).

About the relationship of cdrecord and cdrskin

-First of all: this relationship is single sided, as cdrskin has to be aware of -cdrecord but not vice versa. -
-
-I am a long time user of cdrecord and it works fine for me. -Especially i do appreciate its write mode -tao which allows to pipe arbitrary -data on CD and CD-RW via stdin. cdrecord is reliable, versatile and well -maintained. So for me - there would be not problem with it. -
-But the author of cdrecord and the Linux kernel people foster a very hostile -relationship. Ok, that's their business, not mine (or ours if you are with me). -One has to be aware, though, that this relationship might lead to a situation -where cdrecord is no longer available for certain Linux kernels. -
-To have my own project prepared for such a time, i began to implement its -cdrecord gestures on top of libburn. -From now on i invite other interested users of cdrecord to teach cdrskin -the gestures necessary for their cdrecord applications. -Contact me. Let's see what we can achieve. -
-
-I am aware that libburn and cdrskin still have way to go until you can simply -install cdrskin as cdrecord and may expect any application to run with it. -Currently i do not encourage this approach, but of course such a replacement -opportunity is the long term goal of a cdrecord compatibility wrapper. -
-
-It is very important to me that this project is not perceived as hostile -towards Joerg Schilling and his ongoing work. -I owe him much. For cdrecord, for mkisofs, for star. Chapeau. -

It is intended that the sysadmin -controls drive accessability by rw-permissions of the drive rather than -by x-permission of the burn binary. To be usable with cdrskin, the drive -has to offer both, r- and w-permission. - --------------------------------------------------------------------------- - ---fifo_start_empty is a throughput enhancer for unsteady data streams -like they are produced by a compressing archiver program when piping to -CD on-the-fly. It makes better use of the general property of a FIFO -buffer to transport surplus bandwidth into the future. Yep. A time machine. -One-way, i fear. - -FIFO originally was introduced by cdrecord's author Joerg Schilling in order -to protect mediocre burner hardware from suffering buffer underruns -and thus producing misburns (at 1x speed on CD-R media at the price of a -DVD-RAM nowadays). This purpose would not justify a fifo any more - -given the limited life time of burners and the seamless underrun protection -of contemporary consumer drives. - -With an unsteady data stream the task of the buffer is to soak up peak -performance and to release it steadily at the drive's maximum speed. -The larger the buffer the more reserves can be built up and the longer -input drought can be compensated. - -Original cdrecord has the historical property, though, to first wait until -the buffer is completely filled. Best practice for fighting drive -underruns, of course. -With a very fat fs=# buffer (128 MB for 12x CD is not unrealistic) this -can cause a big delay until burning finally starts and takes its due time. - ---fifo_start_empty makes cdrskin start burning without waiting for the -FIFO to be full resp. the data stream to end. It can make use of the -seconds spend with drive preparation and lead-in, it risks a few drive -buffer underruns at the beginning of burn - but modern drives stand this. - -Note: no FIFO can give you better average throughput than the average -throughput of the data source and the throughput of the burner. -It can be used, though, to bring the effective throughput very close -to the theoretical limit. Especially with high speed media. - --------------------------------------------------------------------------- - ---no_rc allows you to surely ban influence from systemwide or user specific -default settings of cdrskin. Possible locations for such settings: - -/etc/default/cdrskin - -/etc/opt/cdrskin/rc - -$HOME/.cdrskinrc - --------------------------------------------------------------------------- - -tao_to_sao_tsize= allows the - actually unsupported - cdrecord option --tao and defines a default track size to be used if - as custom with -tao - -no option tsize=# is given. - -Since -tao is supported in cdrskin-0.2.5 the TAO-to-SAO workaround on its way -to obsolescence. Nevertheless, tao_to_sao_tsize= allows to preset a default -size for SAO mode which is in effect only if no track size is available. - -As in general with cdrskin tsize=# the data source does not have to provide -the full annouced amount of data.

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 aquired drive you can blank a CD-RW - libburner_blank_disc() - Between blanking and burning one eventually has to reload the drive status - libburner_regrab() - With the aquired drive you can burn to CD-R or blank CD-RW - libburner_payload() - When everything is done, main() releases the drive and shuts down libburn: - burn_drive_release(); - burn_finish() - -*/ - -/** See this for the decisive API specs . libburn.h is The Original */ -/* For using the installed header file : #include */ -/* This program insists in the own headerfile. */ -#include "../libburn/libburn.h" - -/* libburn is intended for Linux systems with kernel 2.4 or 2.6 for now */ -#include -#include -#include -#include -#include -#include -#include -#include - - -/** For simplicity i use global variables to represent the drives. - Drives are systemwide global, so we do not give away much of good style. -*/ - -/** This list will hold the drives known to libburn.
