Wish: A write mode like cdrecord -tao

[scdbackup@…]

With cdrecord -tao it is possible to pipe a data stream onto CD.

libburn is not able to perform a similar stunt because it always needs to know the track size in advance. Either by using a file as data source or by announcing a fixed size with burn_fd_source_new().

Due to this drawback, cdrskin is more cumbersome to use than cdrecord. The only workaround is to announce a generously overestimated size which leads to overly long writing times in many cases.

From my poking around libburn and test/master, it looks as though tao mode in fact exists in libbern but is broken. This ticket should probably be changed from enhancement to defect and should probably be retitled broken tao mode in libburn. My apologies if this is actually a work in progress rather than a bug.

I'm currently sifting my download of icculus.org/burn mailing list archives

(cd icculus_mailinglist_archiv ; for i in *.gz ; do gunzip <$i ; done ) | less

Very nostalgic (sniffle) my mail of: Date: Sun Dec 4 09:51:03 2005 : It lasted 4 days from first find to first success. cdrskin is a Glueckspilz (i.e. astoundingly lucky). By now i know that it could as well have failed miserably.

There have been several attempts to implement TAO but none seems to have yielded long lasting success. (Maybe i should have asked less often for it.) Could well be we are as near to TAO as we were to -eject , to -audio and to proper track number report. (I am still bouncing on my chair about these pieces of progress.)

[scdbackup]

Difference of TAO versus SAO (learned from MMC-1, MMC-3, from watching cdrecord and from googling about "cdrecord" "CLOSE TRACK" "5B"):

No CUE sheet and no lead-in is to be written for TAO.

TAO tracks need to be closed via SCSI command CLOSE TRACK/SESSION.

TAO sessions need to be closed via SCSI command CLOSE TRACK/SESSION.

The first TAO track has to start at lba 0 and not at -150. (Because auto-lead-in ?)

(libburn specific : One shall not apply function scramble() to TAO sectors which is not done with SAO either. Hopefully there are not many more spots in libburn code where TAO is not taken into respect properly. I found a few.)

The change stamps which mark my endeavor so far in libburn source are "ts A61030" and "ts A61031". Start revision is 337, current is 338.

Revision 339 is the first where cdrskin is able to do

stream_producer | cdrskin ... -data -tao -

without any predicted size.

To enable this, cdrskin for now needs to be compiled by

cdrskin/compile_cdrskin.sh -experimental

There is still quite some work to do, before -tao can become default writing mode.

[scdbackup]

TAO is now default for single track burns and for burns where stdin without a fixed size is source of one of the tracks. SAO is used by default for other multi-track burns. Options -tao or -sao set the write mode explicitely, of course.

Hopefully, the tips presented herein on matching jewelries will be of assistance. Keep in mind that the jewels are well fit for your skin color, occasions, dresses, qualities, etc. to stand out the decorative effect of jewels. The most important principle: don't make your jewels go the same with your face shape as well as go opposite to it. Softening and width are needed for rectangle faces. Therefore, shorter necklaces or round necklaces work nicely for people with this kind of face. To sum up, from what we have discussed above, it is easy for us to draw a conclusion that the jewelries that you chose should go well with your face shape and hair style to let you be more attractive. Fancy clothes coordinating links of london sweetie bracelets with slight tint could be better. When having dinners, authentic jewelries will let you become the incarnation of nobility and elegance.

The brilliant and shining jewels with special styles will draw the attention of the young people.
