Code: Select all

tcrequant -i movie.m2v -o shrink ed.m2v -f 1.5 

It doesn't work, all I get is a "shrink" file. And dvdrip is a PoS. Like most "free" software, it's half-assed, amateur built.

See the -o part? That's the output file name...there's an extra space put in there by error - it should say "shrinked.m2v".

I thought the "shrink" part was a parameter. Ya know, like this:

Code: Select all

mount -t iso9660 -o auto, loop=/dev/loop0 ripped_dvd.iso /foobar

The way it was shown was ambiguous.

I did as you said and got the m2v and ac3 files:

Code: Select all

foo@bar:/dvd/mash> ls -lh mash.m2v 
-rw-r--r--  1 foo users 7.0G Dec 19 19:16 mash.m2v
foo@bar:/dvd/mash> ls -lh mash.ac3 
-rw-r--r--  1 foo users 228M Dec 19 19:21 mash.ac3

Buy XP, use DVD-Shrink - whinging sorted . As always, I say to people who make such comments "write a better one!", and claiming not to be a coder doesn't cut it...

My point is that a lot of that software does not function well. Granted, most of it does all right, and it does all right enough that I use Linux as my everyday O/S, but it's not the case that everybody who runs XP is a jackass simply because a lot of the software for Linux is, frankly, wanting.

Speaking of which, mplex still doesn't work:

Code: Select all

I know that file is bad because:

Code: Select all

foo@bar:/dvd/mash> ls -lh final.mpg 
-rw-r--r--  1 foo users 6.0K Dec 20 23:48 final.mpg

What did I do wrong here?

[ian!]

I don't know why this thread hasn't been moved earlier.
Moved from 'Multimedia'.

[mnxAlpha]

That's because the output file is going to be greater than 2GB, and mplex is being careful (in case you're running a system that can't deal with files greater than 2GB). I can run mplex on files far larger than 2GB without any problems, and without any additional command-line options. Maybe mplex didn't get compiled with large file support for some reason?

However, you could try this:

Code: Select all

mplex -f 8 -o final-%d.mpg mash_shrunken.m2v mash.ac3

That'll give you some sequentially numbered mpg files. You can stick them back together like this:

Code: Select all

cat final-*.mpg > final.mpg

Obviously, delete them when you're finished. Not the ideal solution, but it should work.

Hey!

Where can I get dvddirgen from? -Which package is it in?

Cheers,
A.

[kc8tbe]

Good question.

dvddirgen is part of the dvdauthor package, but you won't find it after version 0.6.8. From the changelog:

rename dvddirgen to dvddirdel to better reflect purpose

As nearly as I can tell, all dvddirdel does is rm everything in the directory you give it. If you give it a nonexistent directory, it does nothing. Personally, I don't use dvddirdel, but go directly to:

Code: Select all

dvdauthor -o empty_dir movie.mpg
dvdauthor -o empty_dir -T

Of course, by the time you get to the second command empty_dir isn't empty anymore.

Hope this helps!

[campenbe]

Just tried your instructions the first time and they worked like a charm. I appreciate that posted them. Thanks!

[brenden]

Code: Select all

tcrequant -i movie.m2v -o shrink ed.m2v -f 1.5 

It doesn't work, all I get is a "shrink" file. And dvdrip is a PoS. Like most "free" software, it's half-assed, amateur built.

dvdbackup is much better.

[hunn]

I found a nice little script which does all the work for you. Works like a charm! (well... still checking it out )

It does almoust the same as in the first post, except it uses mplayer to extract the mpg-stream direct from the DVD:

Code: Select all

mplayer -dvd-device $dvd dvd://$title -dumpstream -dumpfile $path/dv_output/output.mpg

Gets rid of all the vob-troubles

Hope its for any use!

I would like to comment on my experience with this procedure.

First, realize that menus etc. will not work. When I played back my
resulting disc, the first few seconds consisted of rapidly displaying
all the menus and special screens, followed by the main feature. I
saw this on Ogle and one standalone DVD player; two other standalone
players could not handle the disc at all.

Second, mplex wants to split the final mpeg into MANY parts for me --
mjpegtools mplex-2 version 1.6.2 (2.2.3). This is not a matter of
"2GB file size limitations"; it creates over 4000 mpeg files, most
between 4k and 6k in size. I append a small script to demonstrate.
More seriously, each file appears to reset the System Clock Reference,
causing DVDauthor-0.6.10 to fail with the message

ERR: SCR moves backwards, remultiplex input.

I was able to work around this by patching the source to DVDauthor and recompiling as advised on the DVDauthor mailing list.

http://sourceforge.net/mailarchive/foru ... m_id=32261

Finally, audio and video came out badly out of sync.

Perhaps this would work great if I only used the VOBs for the main
feature without the menus and special features. In fact I have
studied several archiving scripts based on transcode and NONE of them
preserve the menus on the original disc -- they all either work on a
single feature or create a new menu (such as eriks-dvd-rip). DVD::Rip
seems promising but so far I only see how to back up to SVCD, not
DVD. In short, the only solution which works for me at this time is
(shame to say) Wine+DVDShrink.

Code: Select all

mplex -f 8 -o final-%d.mpg movie.m2v movie.ac3
touch final.mpg
i=1
while [ -f final-$i.mpg ]
do
  cat final-$i.mpg >> final.mpg
  i=$[$i+1]
done

Seems to work fine for me, thanks
I'm gonna attempt to write a script for this, if I manage I'll post it here

Edit: I just noticed, chapters don't seem to be working - anyone else having this problem?

[m707]

The best native linux solution for a dvd 9 to 5 job is lxdvdrip, as mentioned above, IMHO.

At present it offers all you need except preserving the original menus (if requantization is neccessary).

However, if you include dvdwizard, it will offer you a menu to select your audio $LANG (if more than
one) and gives you a chapter selection menu offering thumbernails of each first sceen. It will preserve
subtitles marked as forced (or concluded in a separated stream marked as forced) and circumvent a
lot of traps some other dvd9to5 tools do not care about at all.

lxdvdrip acts as wraper for a bunch of tools like: mplayer, transcode, mplex, vamps, spu(un)mux, ifo_dump,
dvd(un)autor, streamdvd, dvdwizard, dvdbsckup, growisofs, cdrecord(-prodvd), mkisofs ......

Therefore it offers the greatest variety of choices. The basic concept is to use pipes where possible
(to avoid HD-space usage). It's also offering requanting by using vamps pipes in the dvdauthor
xml syntax, so there is no need to a/v split the stream before requanting ([part]copy)

Of course, you have to spend some time to make you familiar with its options and functionality, but
IMHO its worth a trial if you want to avoid crowding you box using wine/dvdshrink.

At present the most prommising attempts to preserve menus are in dvdunauthor probably using some
possibilities pgcedit is offering, too. However, it is still a real pain to get the job done .

OK OK I only tried to help with an info post, if you dont like it do not use it, just tried to show the whole process can be done in command line, appologies. I am getting pretty tired of sharing knowledge only to be flamed at. I just tried to give something back rather than just taking from the forums.

I appreciate your guide, but it's really frustrating when you ask a question and someone gives an utterly useless answer. If you don't know the answer, don't try to give one.

This is probably mplex error. Has anybody seen this? Is it possible that it has something to do with the DVD imperfection (e.g scratch)?

[m707]

I don't think it is an mplex error. In spite:

Code: Select all

**ERROR: [???] Can't find next AC3 frame: @ 18523904 we have 93c0 - broken bit-stream? 

is a message from mplex I suppose something previous in the toolchain breaks.

At first I would try a different streamtool (-st). My favourits list:

- trans_par
- mplayer
-copy

If you know which titleset it breaks, you can of course have very rudimental scratching check using:

Code: Select all

mplayer -dumpstream -dumfile film.mpg dvd://[TitlesetNumber]

lsdvd should give you a hint in which titleset is the main title. If this does not work, too. I would
try to borrow another dvd of the same content to see if it is really scratch based. In the meantime
the DVD industry set up new weapons (e.g. broken sectors) and I don't know if lxdvdrip will handle it.

If your problems are really based on scraches and the content is not available in new (e.g. some self made
holiday film) you can try to find a CD/DVD polish set to fix the scratches. Probably a copy using ddrescue first
could be of assistance in this case.

[tytus]

Your were right. I tried st=transcode and the problem did not show up. I also tried trans_par and mplayar. Both of this methods seem to be a bit more reliable. But my experience is very short

Thanks

I use dvdshrink with wine: http://forums.gentoo.org/viewtopic-t-333140.html

If you don't mind using wine, and you like the 'click and go' way, it's not bad. You can remove audio tracks/subpictures, and you can keep the extras if you want.

[Dr. Z]

Wine works fine for me but does anyone know how to do it non-interactively?
E.g. I'd like to compress 5 DVD's one after the other in the middle of the night,
without having to get up and click on some buttons and type in paths every
hour or two. Maybe a Wine scripting language, or app-specific DVDShrink scripts,
or some Windows program to generate mouse and key events?

[Rodent]

Great guide, exactly the type of info I was looking for. Thank you so much, you saved me hours upon hours I am sure.

For people complaing about space req. using pipes like the below commands will get it to a min.
BTW, I am just posting to spread information, I don't really want to help people with problems, so RTFM before you ask. And please help out if you figure out how to cat the VOB's directly off the DVD (I can't figure out inline CSS decryption).

Max possible space usage: <=9.0GB (full DVD backup) + ~300MB (audio) + <=4.7GB (burnable dvd file system) == ~14.0 GB (total)
further this maybe slightly faster as its not thrashing your hd as much.

Code: Select all

# - get the vob's you want using whatever tool you want (I like dvdbackup)
#   I find it useful to go though the VOB's with mplayer and cherry pick the ones I want
#   useing file wildcards or just fully list the VOB files after the cat in both commands bellow
#   like "cat VTS_01_1.VOB ... VTS_01_7.VOB | ..." or VTS_01_[1234567].VOB as shown
#   ASSUMEING PWD IS IN VIDEO_TS !!!
# - get the audio out 
cat VTS_01_[1234567].VOB | tcextract -a 0 -x ac3 -t vob > /tmp/dvd-work-dir/my-movie.ac3
# - now extract the video, compress (optional), mplex with audio, and finally write dvd file system
cat VTS_01_[1234567].VOB | tcextract -t vob -x mpeg2 | tcrequant -f 1.5 | mplex -f 8 -o /dev/stdout /tmp/dvd-work-dir/my-movie.ac3 /dev/stdin | dvdauthor -o /tmp/dvd-work-dir/my_movie /dev/stdin
# - remove un-needed crap now 
rm /tmp/dvd-work-dir/my-movie.ac3
rm -rf /tmp/dvd-work-dir/MY_MOVIE_FULL_BACKUP 
# - finally just to be complete, the rest of the above guide follows
# IFO files
dvdauthor -o newdvd -T
# Burn with k3b or like
growisofs -Z /dev/cdrom -dvd-video /tmp/dvd-work-dir/my_movie

And yes this destroys all chapter marks.

Aren't pipes neat, now you know what all the fuss is about.

Dr. Z: if you know what vob files you want writtening a quick bash script should do one dvd at a time. Or all five if the vob files are on you hd already, then you just have to burn the resulting dvd-file structures

[m707]

14 GB != min

Please take a look at lxdvdrip.

E.g. using the vamps backend -st (part-)copy, where vamps-play_title can be used directly in dvdauthors xml file, there is no need to spend more than the 4.3 GB you will burn afterwards. Of course vamps can preserve the chapter structur, can rip subtiltes and can requant mpeg2 without (de)muxing.

Even if you choose any other backend to have a chance to get your own menus using lxdvdrips dvdwizard integration you will not have to spend 14 GB.

[Rodent]

m707: Thanks for your comment.
Like the orginal poster I realize that lxdvdrip (or other programs/scripts) are a cleaner/better solution to backup up dvds. I guess I should of just said that too like everybody else instead of realizing that the orginal (and my) instructions are more for education/fun than use. (didn't like 5 other people already note that lxdvdrip is better)

BTW, it would be possible to get a max of 5GB if there was a command line way of extracting off of the DVD using CSS and send output to stdin (aka pipe it). Yes 9GB of the 14 are because I can't read straight off of the dvd. Of course it is prob. pretty easy to just whip up some c code to wrap the libcss libary into a command like that (note to self: good project to do this semester).

Further I fail to see how it would be possible to "requant mpeg2 without de(muxing)." I am no expert or even that knowledable on the subject but I am pretty sure thats just not possible. You don't have to write the a/v to a tmp file or anything but (de)muxing has to happen somewhere when you requant the video (even if just inline, like I did). Regardless I am going to do some further reading into this.

that would be great, because i find wading through dvd authoring stuff difficult as ripping etc takes a long time.

lxdvdrip is pretty much install/configure, excute, done. As for a guide I don't know what to say except I had to install streamdvd. And edit /etc/lxdvdrip.conf line #37 dvdbrenner=/dev/scd0 to dvdbrenner=/dev/dvd
