-/* Usage:
- 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
- /my/dvd/backup/dir/TITLE_NAME/VIDEO_TS.
-
- 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 with
- the -n switch.
-
- 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 switch.
-
- However the -t and (-t -s/-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 -a 0.
-
- dvdbackup makes it best to make a inteligent guess
- what is 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/
-
- where "-T 2" specifies that you want to backup
- title set 2 i.e. all VTS_02_X.XXX files.
-
- 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 -s 20
- To backup to chapter 20 from the first chapter use only -e 20
-
- You can skip the -t switch and let the program guess the title although
- it's not recomened.
-
- If you specify a chapter that his higher than the last chapter of the title
- dvdbackup will turncate to the highest chapter of the title.
-
- Return values:
- 0 on success
- 1 on usage error
- 2 on title name error
- -1 on failur
-
-
- Todo - i.e. what's on the agenda.
- Make the main feature guessing algoritm better. Not that it doesn't do
- it's job, but it's implementation it's that great. I would also like
- to preserve more information about the main feature since that would
- let me preform better implementations in other functions that depends
- on the titles_info_t and title_set_info_t strcutures.
-
- 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.

- and audio tracks than the second one and it's title one.
- Done it must be the main film
-
- Hmm the biggest one doesn't have the most chapters?
-
- See if the second one has the same amount of chapters and is the biggest one
- If so we probably have a 4:3 and 16:9 versions of film on the same disk
-
- Now we fetch the 16:9 by default unless the forced to do 4:3
- First check which one is which.
- If the 16:9 is the biggest one and has the same or more subtile, audio streams
- then we are happy unless we are in force 4:3 mode :(
- The same goes in reverse if we are in force 4:3 mode
-
-
- Hmm, in force 4:3 mode - now we check how much smaller than the biggest one it is
- (or the reverse if we are in 16:9 mode)
-
- Generally a reverse division should render in 1 and with a small modulo - like wise
- a normal modulo should give us a high modulo
-
- If we get more than one it's of cource a fake however if we get just one we still need to check
- if we subtract the smaller one from the bigger one we should end up with a small number - hence we
- need to multiply it more than 4 times to get it bigger than the biggest one. Now we know that the
- two biggest once are really big and possibly carry the same film in differnet formats.
-
- We will now return the prefered one either 16:9 or 4:3 but we will first check that the one
- we return at lest has two or more audio tracks. We don't want it if the other one has a lot
- more sound (we may end up with a film that only has 2ch Dolby Digital so we want to check for
- 6ch DTS or Dolby Digital. If the prefered one doesn't have those features but the other once has
- we will return the other one.
