Competent CLI DVD copy program?

Nutria · 05-22-2012, 04:49 PM

Hi,

Distro is Ubuntu 12.04.

I copy my TV and movie DVDs to ISO files so as to have HandBrakeCLI rip away at them without having some GUI app eject a DVD 10 minutes after I go to sleep or head to work, thus doing nothing for hours and hours.

I've tried copying them using cat, dd (neither of which has error correction), readom (started throwing errors 1/2 way through) and readdvd (which silently hung 1/2 way through). No luck with any of them because of CSS encryption, even though readdvd decrypted the keys.

Brasero works great in GUI mode (but there's all that needless pointing and clicking), and is supposed to work in CLI mode, but I can't figure out the magic sauce to make it work.

So... any programs I've overlooked or ideas on how to make brasero work from the CLI?

TIA

This is for TV or a DVD that you are legally allowed to copy.

lsdvd will show you the chapters on a DVD

Code:

mplayer dvd://1 -dumpstream -dumpfile outputfile.vob

Will dump title 1 to file which you can then save or encode.

Do a search on LQ or the web for
mplayer
ffmpeg
mencoder
lsdvd
libdvdcss

Reread your post

To make an .iso mount the DVD (UDF) and then use something like

Code:

dd if=/dev/sr0 of=output.iso bs=2048

or

Code:

mkisofs -R -J /dev/sr0 -o /path/to/output.iso

or

Code:

ddrescue –n –b 2048 /dev/sr0 output.iso

Use your own device nodes and syntax.

Barfs on CSS-encrypted disks.

mkisofs -R -J /dev/sr0 -o /path/to/output.iso

Code:

$ mkisofs -R -J /dev/sr0 -o foo.iso
I: -input-charset not specified, using utf-8 (detected in locale settings)
genisoimage: No such file or directory. Invalid node - '-o'.

That's because mkisofs/genisoimage masters ISO images, not copies them.

Code:

ddrescue –n –b 2048 /dev/sr0 output.iso

Use your own device nodes and syntax.

Code:

$ ddrescue –n –b 2048 /dev/sr0 output.iso
ddrescue: Too many files.
Try `ddrescue --help' for more information.

Anyway, it should barf on encrypted DVDs just as dd does.

Neither dd nor ddrescue should "barf" on CSS-encrypted DVDs, since, as its name says CSS scrambles the content of the disk, not its filesystem. And even if the filesystem would be encrypted or damaged dd/ddrescue simply wouldn't care and copy it anyway.
It may be that there are other copy protections in place and it is not CSS that causes your issues.

By the way, "barfs" is in no way a sufficient error description, it may help to see which error-message you exactly get.

Try somethink like

Code:

dd if=/dev/sr0 of=dvd.iso bs=128 conv=notrunc,noerror

And we are talking about a DVD that is legal for you to copy. Not a copyrighted DVD. That would be a violation of LQ TOS.

You'd think...

Code:

$ dd bs=2048 if=/dev/sr0 of=output.iso
dd: reading `/dev/sr0': Input/output error
73434+0 records in
73434+0 records out
150392832 bytes (150 MB) copied, 30.9552 s, 4.9 MB/s

ddrescue worked, but took forever. GUI brasero Just Worked.

Doesn't appear to be the case, since brasero and dvdread go thru the whole "decrypting CSC keys" process.

That completes successfully, writing out the correct number of bytes, but the sha1sum of the ISOs created by dd and brasero are different.

vlc seems to play the two ISOs the same, so maybe it's just some padding bits at the end.

I bought the DVD from Amazon, if that's what you mean.

That you bought the DVD does not mean that it is legal to copy it. This, of course, is dependent on the country you live in (in Germany it is for example illegal to circumvent any kind of copy-protection).

But on the other hand, the next disk I tried instantly started throwing errors:

Naturally, brasero worked.

You are wrong here ... and may have a look here:
https://de.wikipedia.org/wiki/Privat...ma.C3.9Fnahmen

how could a protection be "wirksam" ... lol

Apparently, some DVDs need to be decrypted first. So, I run cli vlc first for 4 seconds, and then dd.

Code:

#!/bin/bash
cvlc :start-time=1 --stop-time=4 dvd:///dev/sr0 vlc://quit 
BS=$(isoinfo -d -i /dev/sr0 | grep "^Logical block size is:" | awk '{print $5}')
VS=$(isoinfo -d -i /dev/sr0 | grep "^Volume size is:" | awk '{print $4}')
VSID=$(isoinfo -d -i /dev/sr0 | grep "Volume set id: " | awk '{print $4}')
VID=$(isoinfo -d -i /dev/sr0 | grep "^Volume id: " | awk '{print $3}')
if [ -z $1 ]; then 
    if [ -z $VSID ] || [ "$VSID" == "UNDEFINED" ] || [ "$VSID" == "NOT_SET" ] || [ $VID == $VSID ] ; then
        OF=${VID}
    else
        OF=${VID}_${VSID}
    fi
    ls -1 $OF.iso &> /dev/null
    rc=$?
    if [ $rc -eq 0 ]; then echo -e "\n\nFile already exists\n"; exit; fi
else
    OF=$(basename $1 .iso) # just in case I accidentally pasted in a name with .iso
fi
pv /dev/sr0 | dd conv=noerror bs=$BS count=$VS of=$OF.iso
sleep 3
eject /dev/sr0

I have found this problem in the past when ripping DVDs to my hard drive using dd or dcfldd. Does anyone know a way around this without having to open the DVD in VLC or similar before ripping? It's quite tiresome when ripping a box-set for example.

That's the beauty of "cvlc :start-time=1 --stop-time=4": it does the opening and closing of vlc for you.

Ah, thanks, I missed the simplicity there. next time I buy some DVDs I'll be ready.
