Jörg has not posted to this list in many months. For a while now this list has been so quiet I had started to wonder whether everyone moved to another one. I think it is more a case that fewer people are having problems with current tools. Those who do have problems are using forks like wodim in some cases, AFAIK the maintainers (if any) aren't here. A tad more spam filtering would be nice, but clients can do it at their end still. I am sorry Joerg no longer posts here, I suspect I miss his updates if he does them. -- E.

Re: what difference xorriso is it going to make on the user interface?
Thomas Schmitt wrote: Hi, If you imagine the difference between xorriso and older utilities, what do you think is the main difference that can be reflected on the user experience? That is, what difference does it 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 --grow_overwriteable_iso) 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. -- E.

I could probably learn from libcdio if an interested user would show up. xorriso does only sessions with a single data track. cdrskin is able to record pure audio CDs, but not the CD-XA format that is prescribed for CD which contain audio and data tracks. As we are at it, mkisofs can produce HFS images and simple UDF, which xorriso cannot. HFS is needed for production of bootable Debian images for PowerPC. (They still have to use genisoimage for that.) Here i lack entirely of specs and would have to explore open source code. UDF would allow to record video DVDs which comply to the specs for livingroom DVD players. UDF is openly specified as ECMA-167 plus UDF-2.60. Mind twisting.

Hi, We have stacks of CD media and a few people who actually like VCD format, so short stuff does get put in the way. It is a skill which must be refreshed or you wind up working from notes without understanding. Besides, if the tool chain breaks, who would know if we didn't do this? There are few complaints about cdrecord and wodim with CD media. A while ago i had a conversation with an interested person where we sketched CD burning from a user supplied cue sheet, i.e. user controlled SAO. It seemed mostly about translating the terminology of e.g. cdrdao back to the MMC specs. Well, as so often, the interested person had other things to do. HFS is needed for production of bootable Debian images for PowerPC. UDF would allow to record video DVDs which comply to the specs for livingroom DVD players. But you can generate an image to a disk file and burn it as just data for many of these (which don't need arcane write formats). I confess that we burn ext2 filesystems to DVD, since they are for use with Linux systems and ISO9660 is not needed. We just write them to a file loop mounted and formatted, then burn the image. In the past i did this with afio and star archives. Meanwhile my backups are entirely based on xorriso. But the HFS needed for Debian GNU/Linux powerpc has to co-exist with an ISO 9660 image that points to the same files. (Aka hybrid image.) The boot facility of the IBM needs HFS and hands over to Debian which then expects ISO 9660 ... if i understood it right. The DVD video UDF is an extra primitive one with certain predefined directory and file names. See http://en.wikipedia.org/wiki/DVD-Video I doubt you can get this from the read-write UDF driver of a Linux kernel. Luckily there are no different sector formats like with CD. On DVD and BD we only have data sectors of 2048 bytes each. Have a nice day :) Thomas -- To UNSUBSCRIBE, email to cdwrite-requ...@other.debian.org with a subject of unsubscribe. Trouble?
