dvdbackup is a tool to back up your DVDs in whole or part.
To gather info about the dvd:
dvdbackup -i /dev/dvd -I
Gerneral backup information:
If your backup directory is
/my/dvd/backup/dir/ specified with the
-o flag, then dvdbackup will create a DVD-Video structure under
Since the title is "uniq" you can use the same dir for all your DVD
backups. If it happens to have a generic title dvdbackup will exit
with a return value of 2. And you will need to specify a title name
dvdbackup will always mimic the original DVD-Video structure. Hence if
you e.g. use the
-M (mirror) you will get an exact duplicate of the
original. This means that every file will be have the same size as the
original one. Like wise goes also for the
-F and the
-t and (
-e) switch is a bit different the
titles sectors will be written to the original file but not at the
same offset as the original one since they may be gaps in the cell
structure that we don't fill.
To backup the whole DVD
dvdbackup -M -i/dev/dvd -o/my/dvd/backup/dir/
This action creates a valid DVD-Video structure that can be burned to a DVD-/+R(W) with help of mkisofs version 1.11a27 or later
To backup the main feature of the DVD:
dvdbackup -F -i/dev/dvd -o/my/dvd/backup/dir/
This action creates a valid DVD-Video structure of the feature title set.
dvdbackup defaults to get the 16:9 version of the main feature if a
4:3 is also present on the DVD. To get the 4:3 version use
dvdbackup makes it best to intelligently guess the main feature of the DVD - in case it fails, please send a bug report.
To backup a title set
dvdbackup -T 2 -i/dev/dvd -o/my/dvd/backup/dir/
-T 2 specifies that you want to backup title set 2 i.e. all
This action creates a valid DVD-Video structure of the specified title set
To backup a title:
dvdbackup -t 1 -i/dev/dvd -o/my/dvd/backup/dir
This action backups all cells that forms the specified title. Note that there can be sector gaps in between one cell and an other. dvdbackup will backup all sectors that belongs to the title but will skip sectors that aren't a part of the title.
To backup a specific chapter or chapters from a title:
dvdbackup -t 1 -s 20 -e 25 -i/dev/dvd -o/my/dvd/backup/dir
This action will backup chapter 20 to 25 in title 1, as with the backup of a title, there can be sector gaps between one chapter (cell) and on other. dvdbackup will backup all sectors that belongs to the title 1 chapter 20 to 25, but will skip sectors that aren't a part of the title 1 chapter 20 to 25.
To backup a single chapter e.g. chapter 20 do
-s 20 -e 20
To backup from chapter 20 to the end chapter use only
To backup to chapter 20 from the first chapter use only
You can skip the
-t switch and let the program guess the title
although it's not recommended.
If you specify a chapter that his higher than the last chapter of the title dvdbackup will truncate to the highest chapter of the title.
- 0 on success
- 1 on usage error
- 2 on title name error
- -1 on failure
Todo - i.e. what's on the agenda.
Make the main feature guessing algoritm better. Not that it doesn't do its job, but its implementation isn't that great. I would also like to preserve more information about the main feature since that would let me perform better implementations in other functions that depend on the titles_info_t and title_set_info_t structures.
Make it possible to extract cells in a title, not just chapters (very easy so it will definitly be in the next version).
Make a split mirror (
-S) option that divides a DVD-9 to two valid
DVD-5 video structures. This is not a trivial hack and it's my main
goal the next month or so. It involves writing ifoedit and vobedit
libraries in order to be able to manipulate both the IFO structures
and the VOB files. Out of this will most probably also come tscreate
and vtscreate which will enable you to make a very simple DVD-Video
from MPEG-1/2 source.
