Re: cdrskin + k3b doesn't work SOMETIMES

Hi,

it can hardly be the reason for cdrskin
stalling, but after reading man cdrecord
the use of option -xa1 appears to be a bug
in K3B:
"       -xa1   If  this  flag  is present, all subsequent tracks are written in
              CD-ROM XA mode 2 form 1 format. The data size is a  multiple  of
              2056 bytes.  The XA sector sub headers are part of the user data
              and have to be supplied by the  application  that  prepares  the
              data to be written.
"

The preparing application is mkisofs.
I see no hint that it would produce
those 8 bytes sub headers.

In man mkisofs i read
"
       -sectype sector type
              Set  the  sector  type  to  be used for the output file with the
              iso9660 filesystem.  The sector type may be one of:
              xa1    This  sets  the sector type to CD-ROM XA mode 1 with 2056
                     bytes per sector.  This sector type is the official  sec-
                     tor  type  for  multi-session  CDs,  it  should  be  used
                     together with the -XA option of mkisofs.  It is  required
                     to  write Kodak Photo CDs and Kodak Picture CDs.  Use the
                     -xa1 option from cdrecord to tell cdrecord to  write  CD-
                     ROM  XA  mode  1  sectors.   Do not use for DVD or BluRay
                     media.
"

I do not see options -sectype or -s in
the reported mkisofs options.

Possibly you have to discuss this with
K3B.
Is there a button "Multi-Session" or so ?


For cdrskin this means that it would have
to cut off the 8 bytes of correctly prepared
-xa1 blocks. It would then not work correctly
with input blocks of size 2048, though.
I will have to explore this.


Have a nice day :)
