Re: what difference xorriso is it going to make on the user interface?

If you imagine the difference between

make if a desktop DVD burning application make use of xorriso that it can
offer a unique feature or competition advantage over others?
The combination of mkisofs, cdrecord and growisofs still covers most
needs of the users. One needs to know the particular properties of the
various media types, though.
I consider xorriso to be more consistent in its unified view on all
kinds of storage media: CD, DVD, BD, block devices, disk files,
character devices, pipes.
This advantage is best visible if one uses its own commands rather than
the emulations of mkisofs and cdrecord. Nevertheless, the cdrecord
emulation extends the CD multi-session model for ISO 9660 images to
nearly all DVD types and to both BD types. (Use option
xorriso covers the whole life cycle of an ISO image:
Creation, expansion, manipulation, extraction of files.
It lists the existing sessions and helps with mounting any of
them on Linux and FreeBSD. (Solaris is incapable in some cases.)
It has strong extra features for data backup.
- MD5 checksums of each data file and of the whole session. It has
commands for verifying the checksums and for printing them.
- Incremental backups may be based either on inode+time, MD5, or
plain comparison of file contents.
- Transparent zisofs compression (readable on Linux only).
- Visible gzip compression.
- External filter programs for other compression or encryption.
(Quite slow due to forking the filter processes twice per
filtered data file.)
- Recording and restoring of Linux ACLs and Linux xattr.
- Fast mass extraction of files without rattling the DVD drive.
xorriso is prepared to serve as slave process under a frontend
program. Its options -dialog, -mark and -pkt_output allow the master
to send commands into xorriso's stdin and to receive their results
and messages from xorriso's stdout.
Last but not least, i try to offer user-friendly support. :))
That you do.
The one feature of cdrecord which seems to be unique is burning VCD and
SVCD images. Since the price of DVD media has dropped and more people
have hardware support, use of CD for video is a very special case.
I confess I have not used anything other than cdrecord to burn audio CD,
so I can't speak for how well that works in other tools.
And I still use command line tools directly, based on decades of
experience with tools which sit between the user and the command line
tool, they have a tendency to make the the process easier to use, and
and to make work.

It seemed like a good idea at the time
