[Libcdio-devel] Are you still looking for CD/DVD/BD burn volunteers ?

[Thomas Schmitt]

Hi,

by accident i stumbled over 
  http://www.gnu.org/software/libcdio/
and the call "Volunteers Wanted".

Well, i am developer in a project that has the
described goal. As far as it is for ISO9660 it
can well compete with cdrtools plus dvd+rw-tools
on Linux and FreeBSD. GPLv2. No cdrtools genes.
  http://libburnia-project.org/
  http://freshmeat.net/projects/libburnia

Three libraries are provided:
- libburn writes to CD, DVD, BD, most file types,
  reads from CD, DVD, BD, regular files and
  block devices.
- libisofs eventually loads ISO 9660 images,
  manipulates the image model and writes sessions
  to file or to libburn.
- libisoburn uses the other two libraries to
  implement ISO 9660 Rock Ridge multi-session as
  uniformly as possible for all media supported by
  libburn.

My command line application xorriso demonstrates
the combined capabilities of our libraries. It
comes either with the libisoburn tarball or as
standalone tarball with own library copies from
  http://scdbackup.sourceforge.net/xorriso_eng.html
  http://freshmeat.net/projects/xorriso

Actually it outperforms mkisofs quite clearly
when it comes to backup use cases.

------------------------------------------------

I read in the call for volunteers:
"Technically, it seems the ideal result would
 be enhancements to libcdio at the library
 level to support the necessary writing
 functionality."

libcdio and libburnia intersect with ISO 9660
reading. But if yours can operate on an ISO tree
of many files without needing much memory, then
it can outperform ours with the read cases.


Would you be interested in reading extra info
which describes ACL and xattr of files in an
ISO 9660 image ?
  http://libburnia-project.org/wiki/AAIP

xorriso can produce such images for backup
purposes. Linux mount works with them but
does not show ACL or xattr, of course.
 
------------------------------------------------

"There are other libcdio projects that await
 volunteers, too; UDF filesystem support is one
 big one."

Oh well, ECMA-167 and UDF 2.60 are so ugly that
i use any excuse to escape from the plight to
make a nice diagram and to evaluate the
possibility of single and multi session within
libisofs.
If it was not for DVD movies then i would just
refuse to deal with that format.

Do you have by chance any unfinished work on
that topic which i could exploit ?
It would be mainly about how to combine the
many abstract building blocks described in
ECMA-167.


Have a nice day :)

Thomas
