Looping Statement

[Vectorman]

I am writing a script that will help me automate me ripping my DVD collection.
Here's how I currently do the rip and encode

Insert the DVD and run lsdvd
With this command I get output to the terminal window like this

Disc Title: DVD_VIDEO
Title: 01, Length: 00:45:11 Chapters: 06, Cells: 06, Audio streams: 02, Subpictures: 00
Title: 02, Length: 00:44:25 Chapters: 06, Cells: 06, Audio streams: 02, Subpictures: 00
Title: 03, Length: 00:44:25 Chapters: 06, Cells: 06, Audio streams: 02, Subpictures: 00
Title: 04, Length: 00:44:28 Chapters: 06, Cells: 06, Audio streams: 02, Subpictures: 00
Longest track: 1

After looking at this and deciding that I want to rip every title on this disk I run the following script for every title

mplayer dvd://<titlenumber> -dvd-device /dev/hdc -dumpstream -dumpfile <dirname>/<moviename>

After the Dump is finished
I run the following script to encode the raw dump to an AVI file.

mencoder <moviename> -ffourcc divx -aid 128 -ni -oac aac -ovc lavc -lavcopts \
vcodec=mpeg4:abitrate=128:vbitrate=<rate>:vhq:vpass=1:vqmin=2:vqmax=31:threads=2 -vf scale=320:240 -ofps <output> <dirname>/<moviename>.avi
mencoder <moviename> -ffourcc divx -aid 128 -ni -oac aac -ovc lavc -lavcopts \
vcodec=mpeg4:abitrate=128:vbitrate=<rate>:vhq:vpass=2:vqmin=2:vqmax=31:threads=2 -vf scale=320:240 -ofps <output> <dirname>/<moviename>.avi


What I would like to do is to have a script that will go through the lsdvd output and set up the script to rip and encode all Titles on the Disk to a directory that I choose.

Any Help would be greatly Appreaciated

not as easy as you think, since in all practicality most dvd's have a bunch of usesless titles, and one main title for the movie, however "episode" based dvd's like from a tv-series have the epsiodes split into seperate titles, so having one broad and generic script for both is kind of a pain, its easier to write two scripts, one for movie dvd's and one for multi title dvd's

[Vectorman]

I'm Sorry. It's been a long day. I meant to specify that I am only working on the TV Series's that I have.

The script doesn't have to be completly Automatic.

it should probly ask me that titles I want to rip. and the names of those titles. Then take that information and create a script that will rip and encode the DVD's

After I get a handle on this I will be creating a script to do the Theatrical Movies. But not yet.

Thank you for the prompt response

Unless you have a smp box, take threads=2 out of that script...
DVD's vary widely in their structure, so writing a script, to me, is pointless. I'd do it by hand...
mplayer dvd://1 -chapter 2-2 -dumpstream -dumpfile blah # for title 1 chapter 2 only
or something like that....

[Vectorman]

Thanks for the advise about the threads=2 command... I'm not running this on a SMP machine.

The reason I wanted a script to automate the ripping and encoding is that I would like the computer to work through the night and have the entire DVD ripped by the time I awake the next morning. Same with while I'm at work. I have A LOT of TV series that I would like to rip and do not want to sit at the computer every hour typeing commands into the computer to rip them.

I think I have a handle on the Script so far. Unfortunatly I'm at work right now so I can't post the script. I will post it up here when I get home.

I do however have a couple more questions.
The Command lsdvd output looks like this

Title: 01, Length: 00:45:11 Chapters: 06, Cells: 06, Audio streams: 02, Subpictures: 00


Does anyone know the SED or AWK syntax to get the time out of it so I can associate it with a variable?

Also je_fro,
in your script you use ask the user to input the time in minutes. Is there a way to use the time gathered from the above sed script and use that for the calculations your script uses?

So far I have the basic script set up to do the TV series but it needs a few modifications and enhancments. I'll post what I have here when I get home.


Thanks for any help and advise.

If you find a way, be sure to let me know :D

btw, i updated my xvid script to have manual title support menc -title 2 for example, no -title option will use the lsdvd output for the largest title

[Vectorman]

I looked into the Time thing a little more. Now I do not have Linux or Bash at work but I'm thinking this will work.

Take a look at this and tell me if it will work

This is the output from lsdvd -t 01

Title: 01, Length: 00:45:11 Chapters: 06, Cells: 06, Audio streams: 02, Subpictures: 00


Here is the script that I believe will remove the time code from the above output and calculate the Number of Seconds.


$hours=$(lsdvd -t 01 | cut -c 20-21)
$minutes=$(lsdvd -t 01 | cut -c 23-24)
$seconds=$(lsdvd -t 01 | cut -c 26-27)
$calctime=$((($hours*3600)+($minutes*60))+($second s))



Thanks for all the help

As promised I am posting the Script that I am working on.

The Portion of the script dealing with TV series works beautifully. Unfortunatly I am having some problem with the Theatrical Movie Portion (the portion of which rips the chapters)

here is the lsdvd output for when I do the Theatrical Movie telling it to break it up into chapters

Title: 01, Length: 00:45:11.266 Chapters: 06, Cells: 06, Audio streams: 02, Subpictures: 00
Chapter: 01, Length: 00:03:36.266, Start Cell: 01
Chapter: 02, Length: 00:10:21.276, Start Cell: 02
Chapter: 03, Length: 00:09:08.076, Start Cell: 03
Chapter: 04, Length: 00:08:43.220, Start Cell: 04
Chapter: 05, Length: 00:12:47.200, Start Cell: 05
Chapter: 06, Length: 00:00:33.286, Start Cell: 06


and here is the error I get

libdvdread: Using libdvdcss version 1.2.5 for DVD access
libdvdread: Using libdvdcss version 1.2.5 for DVD access
./dvdrip: line 165: 08: value too great for base (error token is "08")


I can get it to work for the first two chapters on the title but after that I get the above error.

Any ideas?
