Get video DVD title string for shell script?
 

Should be a simple one:

How can I grab the title string of a video DVD for a shell script? I want to write a script that runs dd on disc insertion, and I want to set the title of the iso file to the title of the DVD.

um ... FC2 does this sort of thing for you: i.e. without requiring you to write a script to do it. You go to the main menue > preferences > CD and DVD. Theres a place to stick in the command you want to run and a radio button to check to run the command on insertion.

Our moderator acid_kewpie has made a nice DVD ripping tool called acidrip. This requires a tiny little helper utility called lsdvd which you could use: lsdvd -c | grep "Disc Title" | gawk '{print $3}' should give you the title of the inserted DVD.

Not there
 

I don't have a CD and DVD menu item under Preferences. Is that an optional install? I'm using FC 2.

The utility dd will not work on DVD video disc. I suggest vobcopy or dvd::rip (transcode). vobcopy can list the title of the disc and also rip the whole disc. Then you can use mkisofs or growisofs to make an ISO image. mplayer's mencoder loses audio and video sync so I suggest not using acid::rip.

It's worked for me (but I'm tricking it)
 

I'm assuming you're telling me dd won't work because of the disc protections? I'm using a workaround for that, in which I call a program that uses libdvdcss right before dd.

I like your suggestion, though, and I will try that. I don't want to transcode anything, so I won't use mencoder.

Thanks.

Not there??? Huh?!
 

Good grief - well I have FC2, a standard install, and it's right there off the main menue in Gnome. The command is "gnome-cd-properties" which will also call the dialog from terminal. However, if you use KDE...?

Re: Not there??? Huh?!
 

Hehehe. Yes. I'm on KDE. I should have mentioned that.

This script could be useful for the purpose. It gives you the infos you need to rip a DVD. Some extra programs are required such as
lsdvd
streamanalyze
streamdvd
figlet
The comments are in italian

#!/bin/sh
# dvdinfo.sh
# script per rilevare le informazioni di un DVD VIDEO. Richiede streamanalyze e lsdvd
# Per poter estrarre il DVD bisogna avere installato streamdvd.
clear

# directory dove verranno creati i files temporanei
dir=/home/$(whoami)/tmp_dvd

read film

audio=`lsdvd -t "$titolo" -v -a | grep Italiano | grep ac3 | awk '{print $20}'`
clear

streamanalyze -i /dev/dvd -t $titolo -s 0xe0,$audio 1>&/$dir/$film

capitoli=`grep Chapters $dir/$film | awk '{print $4}'`

Hope this helps

cheeskeeper: don't sweat it - you asked for a script... you had no reason to know that Gnome had a built-in to deal with what you wanted. Now... re: ripping dvd's, you seem to be in good hands...
