[gentoo-user] {OT} dvdrip permissions error, alternative?

[Grant]

When I click on "RIP Title" in dvdrip, I get a permission denied error
regarding Project.pm.  All of the other options in the other tabs are
grayed out and unmodifiable.  If I try to run the program as root, it
says it cannot open the display.  Does anyone know what's wrong here?
I've tried amd64 and ~amd64 versions.

I'm trying to make backups of my DVDs that are smaller than the full
8GB but don't lose any noticeable audio or video quality.  I'd be
happy to just select the audio and video track I want and rip them
without any transcoding.  Would anyone recommend a program other than
dvdrip for this?  I would use mplayer's mencode, but mplayer can't
play my "The Life of Mammals" DVD so I don't think mencode will work.
I believe that DVD is copy protected.

stop running it as root.

correct the permissions on the /dev/ files and the dir you try to write too.

Make sure, the user is in the right groups.

Hi Grant,

 Try the following:

 As user (not as root) become root with "sux" not with "su".
 Or as user gove root "access permission" to your X server with
 "xhost" (-> see manpage).

 I f this does not help:
 sux to root and check the DISPLAY environment variable, whether it
 is correctly set. Should something like  ":0.0" or "localhost:0.0".

 The above are fixing (may be) the symptoms, not the cause of the
 problem.

 These are comeing from the wrong permissions set for the file
 Project.pm .

 ...but when it is emerged, it should be correctly set.

 At this point I have no clue, whether wrong permissions are given 
 to that file/to those files of package.

 Only my two cents, your currency may vary...

 HTH and keep hacking!

What's the error?
I've run dvdrip for a long time and don't get any errors.

dvd9to5. If you don't put a blank dvd into the drive it'll leave a DVD image 
under 4.7GB.

I do my DVDs with both dvd9to5 and dvdrip (at 192Kbps MP3 audio, 1500Kbps 
video) and the quality is all but perfect (1800Kbps video should easily clear 
up the very very small lose).

Embarassing, but I needed to change the CHANGE_ME paths to eliminate the errors.

I've been experimenting with dvdrip and it seems like if I want
perfect image quality I'll only save about half the space and the
process is such a mess.  It's time-consuming and lossy.  I think I'll
stick with:

dd if=/dev/dvd of=image.dvd

and pay a $2 storage fee per movie instead of $1.  That's perfect
quality, all the features, and full menus.  I could see it if you're
trying to fit a movie on a CD or a single-layer DVD, but it doesn't
make sense to me for hard disk backups.

I wish there was something like FLAC for video so you could make a
perfect backup and the only option to be concerned with would be time
vs. space.

That won't work on CSS scrambled discs. You'll copy the scrambled data
but not the key. Instead, use vobcopy followed by growisofs.

What about this (it's what I've been doing):

lsdvd && dd if=/dev/dvd of=image.dvd

Is there any advantage to creating an ISO filesystem out of the image
if you aren't going to burn it?  Also, is there any way to compress
the image without doing any kind of transcoding or that type of
reprocessing?

Does it work with scrambled DVDs? The CSS key is supposed to be stored in
a separate area that is not available on recordable DVDs.

Not really, the likes of mplayer can play from a DVD image directory as
easily as an ISO image.

I'm not dealing with recordable DVDs at all.  I'm making backups of my
store-bought DVDs to my hard drive.

I'm not totally clear on how scrambled DVDs work, but I can tell you
that the dd command alone doesn't work, but adding lsdvd at the front
does.  Also, my "The Life of Mammals" DVD won't play back in mplayer
or totem, but VLC plays it fine either straight from the DVD or from
the hard drive after lsdvd+dd.

yes. ease of transfer, keping everyting togther. still playable with xine 
dvd://path/to.iso

why are you naming it image.dvd instead of image.iso?

the mpeg streams on the dvd ARE compressed. thats what the mpeg codec does. 
You can try the usual suspects - zip, bzip etc, but you won't get far. 

programs that reduce the size of DVD9 so that they will fit on a DVD5 usually 
requantise the stream, I am not sure what that means, but it is much quicker 
than transcoding to another codec like xvid. xvid will, of course, give you a 
much smaller avi file. 

the analogy with flac is not really appropriate. flac is a lossless 
compression, you start with an uncompressed wav file and end up with a 
losslessly compressed audio file. A DVD is already lossy compressed to mpeg2, 
so it is not logical to make an analogy with flac. As I said, you can 
requantise, but of course you lose something...

Increasing the quantization increases the number of pixels represented by a 
single data element in the stream.  From what I understand, MPEG2 does 
very JPEG like compression, meaning that square groups of pixels with 
almost the same color will be stored as a single data element with the 
average color (and maybe some hinting).  Increasing the quantization 
further merges some of these groups together, resulting in both quality 
and size reductions.

Agreed.  There are a number of lossless video codecs out there ( 
http://en.wikipedia.org/wiki/List_of_codecs#Lossless_data_compression_2 ), 
though certainly none are in wide use.  I'd wager that since your are 
starting w/ an already compressed stream, converting to a lossless format 
would actually make the video larger.  With DVD it isn't practical to 
transfer uncompressed video, perhaps we might see some uncompressed video 
available with HD-DVD or Blu-ray.

dd copies bit for bit. you copy an ISO filesystem to another place, you
get an ISO file system.

That's not true.  The CSS key is in the standard filesystem data, not in 
some subtrack data.  Before I found dvdbackup I used the method (with a 
few modifications, like the conv=noerror option and adding a call to 'pv' 
in the pipline to give myself a progress bar) exclusively and rarely ran 
into a disk that had issues.  Those disks could be ripped with k3b's copy 
DVD image... function, which I guess uses the equivalent of cd-paranoia 
for DVDs, and also retries errors (like conv=noerror), but still just 
gives a .iso as output.

You're right. I read this information some years ago in a normally
reliable source, and saw no reason to doubt it as it made sense. bit I've
just tried a dd copy and it worked. It failed on the first attempt, but
after running lsdvd, it worked for the whole disc, and mplayer played it.

I'm not a native English speaker, and I wonder about these Pooh jokes

anyone care to explain to me where the joke is? I'm sure it's funny as

You know Winnie the Pooh right? That lovable bear who is the namesake of the 
books by A.A. Milne? Christopher Robin? Tigger and Eeyore? More recently he 
has been hijacked and corrupted by Disney (..just my opinion).

In any event, he would often say 'bother', as others might say 'rats' 
or 'darn' ie: when something trying happens. I think the sig is just a play 
on this coupled with Pooh trying to connect with a slow modem connection..

While the information above is correct, most DVD devices do not copy the 
particular part of  the filesystem. Their firmware simply doesn't do it.

What is happenning here is that lsdvd is cracking the css keys via
libdvdcss and caching the keys in ~/.dvdcss. If you move the image to
another computer, or try to read it as another user, the keys will
neeed to be cracked again.

dvdbackup doesn't work on "The Life of Mammals" (and surely others)

perhaps there is some newfangled encryption on it. What version of

What do you mean by this? dd simply mirrors the UDF filesystem from the

If you want to extract the files from the filesystem, use vobcopy.

According to someone else's post, the CSS keys would need to be
cracked again if the backup was moved to a different computer.  That's
all I meant.

Would vobcopy -m decrypt the DVD so that it can be played back without
a need to crack or use stored CSS keys?

That does seem to work with the stubborn "The Life of Mammals".  I
wish I didn't have to mount the DVD before running vobcopy though.  I
suppose a mkisofs command after vobcopy would make for a pretty good
process.

vobcopy reads the VOB files directly, rather than reading /dev/dvd as a
video source.

It works for me. I've used it to copy encrypted DVDs that are <4.3GB.

Yeah vobcopy is definitely doing some serious decrypting.  After it
mirrors "The Life of Mammals" mplayer and totem can play it, and with
dd (or straight from the disc) only VLC could play it.  I think I'll
use this command to mount, rip, image, and delete:

mount /dev/cdrom && vobcopy -m -o MOVIE_NAME && mkisofs -l -o
MOVIE_NAME.iso MOVIE_NAME && rm -rf MOVIE_NAME

How can I set that up in a script and execute just the script?

This is also better for performance because the system won't have to
decrypt while it's playing right?

That seems reasonable, although I've no idea how much effort is needed
to decrypt a DVD once the key is known.

Thanks for the script.  I set it up to temporarily use my dd images as
the source, and it looks like the iso comes out about 13MB smaller
than the dd image.  Does that make sense?

Also, mkisofs didn't like -o ${TITLE}.iso and errored with something like:

'.iso' is an invalid atom

Does ${TITLE}.iso need quotes?

I guess that could be down to the encryption overhead.

It shouldn't, because disc names shouldn't include spaces, but it's
probably safest to add them, because shouldn't rarely equals doesn't. The
error looks like it could be caused by a space at the end of the movie
name, although awk should have removed that.

I tried using vobcopy to decrypt my "The Life of Mammals" dd images
and, strangely, it's not working.  vobcopy outputs the same error that
dvdbackup did, something about an error cracking the CSS keys, which
comes from libdvdcss.  VLC plays the post-vobcopy image just fine, but
it won't play in totem and mplayer.  The weird thing is, vobcopy
seemed to decrypt perfectly when working straight from the DVD so that
the image could be played in all the players.  I don't have the DVD
now to test with.

I guess I'll just have to do more testing when I can.

I'm tweaking that script you wrote.  Here's what I have:

#!/bin/bash

echo Enter DVD filename:
read FILENAME
mount /dev/cdrom
TITLE=$(vobcopy -I 2>&1 | awk '/DVD-name:/ {print $3}')
vobcopy -m || exit
mkisofs -dvd-video -V $TITLE -o $FILENAME $TITLE || exit
rm -rf $TITLE
umount /dev/cdrom

Can you tell me what purpose the "|| exit" portions serve?  Also, how
can I run the script by typing /path/to/getdvd?  I've tried:

chmod +x getdvd

and:

chmod 0777 getdvd

with no luck.

'||' is a logical or. When used to chain commands, as in "cmd1 || cmd2"
it means run cmd1, if that fails run cmd2 (if the first command succeeds
and returns true, the OR will alsays be true so there's no need to run
cmd2). All is does here is exit the script if vobcopy or mkisofs return
an error, because there'd be no point in continuing.

That should work, assuming you're i the same directory at getdvd. I keep
my scripts in ~/bin, with the x bits set, and have ~/bin in $PATH, so I
don't need to give the path to run them.

Unless the current directory is in your path, you need to invoke it

export PATH="$PATH:~/bin" or

It's quite common is bash scripts to define a function named die:

die() {
    echo "$@"
    exit 1
}

If you define that at the top of your script you ceplace the above with this:

> vobcopy -m || die "vobcopy failed"

I hope you get the point...

Or, with use of a specific return code:
die() {
  RT=$1
  shift
  echo "$@"
  exit $RT
}

and call it either with the error code of the previous
program:

or your own return code

Just a point a detail, if it can be useful...

"It" here refers to the attempt to copy the disc with dd. The copy failed

This is it's a standard store-bought DVD, this will end up copying the 
encrypted (CSS) data to your HD, which will add CPU overhead at play time.

dvdbackup (in portage) does roughly the same thing, but decrypts once, at 
rip time.  It does no transcoding so everything is at full DVD quality 
(and size). It preserves all menus in mirror (-M) mode, but can also be 
used to rip individual titles.

I have a couple problems with dvdbackup.

It doesn't seem to have an option for mirroring the entire DVD
structure into a single file like dd does, although I suppose a
subsequent command could be used to create an ISO.

The other thing is, it doesn't seem to do so well with my "The Life of
Mammals" DVD.  dd rips it just fine, but VLC is the only program that
will play it.  When mirrored with dvdbackup, a couple of "Error
cracking CSS key" messages are displayed in the terminal, and although
the process does finish, even VLC won't play the image.

That's true, but xine, mplayer, and gstreamer all will play from a 
directory as fast or faster then they will play from an ISO.  I too prefer 
the single-file layout, but it's more important for me to have the CSS 
removed.

Never seen that one, but I'll bet that's a limitation of DeCSS, not 
dvdbackup.  I've sure VLC (when playing the dd image) encounters the same 
issues, it is just more forgiving of dropped or otherwise unavailable data 
in the stream than other clients.  I'm not sure what dvdbackup writes when 
it can't DeCSS. It is probably all zeros or complete trash.  In either of 
those cases it's not surprising all your video players choke on it, even 
if they can handle the case of missing data.

In any case, it makes sense for you to use something that doesn't perform 
the DeCSS at rip time and instead have VLC handle the lack of data each 
time you play it, at least for that DVD.
