How to extract the main feature from a ripped DVD movie?

[Gilbo]

I'd like to extract only the main feature of a DVD movie that I mirrored to my HDD. I made the HDD copies using vobcopy with the -m (mirror) option, so I have a complete mirror of the DVD directory structure on the disk.

I tried using dvdbackup like this:

Code: Select all

$ dvdbackup -i /exports/video/BSG_MINISERIES_A -F -o /exports/video/BSG_MINISERIES_A.feature/

But I receive the following error message:

Code: Select all

Can't read title from DVD device /exports/video/BSG_MINISERIES_A
You must provide a title name when you read your DVD-Video structure direct from the HD

I'm not sure what this means. I guess that it's asking for me to specify the titles I want it to backup. This defeats the purpose of using dvdbackup to extract the feature automatically however, so I'm not sure how to proceed.


Even if I specify a title:

Code: Select all

dvdbackup -i BSG_MINISERIES_A -T1 -o BSG_MINISERIES_A.feature/
Can't read title from DVD device BSG_MINISERIES_A
You must provide a title name when you read your DVD-Video structure direct from the HD

It gives me the error again. What am I doing wrong?

Presently I'm emerging lxdvdrip which is bringing along a small mountain of dependencies for my fileserver, but I was wondering if anyone else has experience with this problem?

Any advice would be greatly appreciated. Thank you for your time .

What are you planning on ripping it to? xvid/ogg? Or mpeg2 again and you just want to remove everything else...

[Gilbo]

For now I'd like to extract it to MPEG2 and just remove everything else.

The big problem for some of the discs that I have is that they're series seasons with several episodes. In many cases 4 episodes will be distributed through something like 6 vobs and I'd like to seperate them out of the vobs. I can't use mencoder to concatenate them, because then I just get one big file with four episodes, one after another.

The overall purpose of this is to be able to burn the episodes back out to DVD-Rs in such a way that I can use single-layer DVDs with just the episodes themselves on them rather than complete dual-layer mirrors of the discs with special features and extras included (which I could do easily). I've been ripping with vobcopy -m, because I want complete archival copies on the hard disk, but that's unnecessary for the new discs I want to make (and would keep me from using nice, common, compatible single-layer DVD-Rs).

if you copy the whole blasted dvd filesystem (full rip) you'll get all the vobs, and with some judicious mplayer scouting you should be able to easily recognize the patterns of which vobs to concatenate, and which to ignore. i find my media players can play .vob's, so at this point you could stop if you felt like it. Or you could compress them into .avi files or something.

[Gilbo]

You're right erik258, in most cases what you describe isn't a serious problem --it takes only a minute or two. However, as I mentioned in passing in my first reply above, in some cases --particularly with TV show seasons on DVD-- you'll have a certain amount of episodes distributed across a different number of vobs. This means you have to find the relevant vobs, concatenate them all, and then split them again. This is quite a pain --particularly the splitting.

I know some programs can, apparently, do this automatically. DVDBackup will, supposedly,and it was this functionality I was hoping to use on my already ripped DVDs, but it doesn't seem to like working on DVD directory structures on an HDD, so I was hoping if anyone knew of a more automagical way of automating this process on the CLI.

Sorry to mildly hijack your thread, but:

I've found that some more recent DVD's are unable to be ripped to my computer; I assume this is due to more advanced copy protection being released, and the lack of new versions of libdvdcss being released. I've tried dvdbackup, Mythtv (actually MythDVD) and vobcopy, and none have worked so far. Does this mean that I should stop trying because no program is likely to work until libdvdcss is updated? I can back them up on Windows, but only with the latest version of AnyDVD, which I think is more evidence that an update would be required.

Thoughts?

dvd ripping is a bit more complicated now. Most DVD's have bad sectors and those bad sectors cause dvdbackup, mytv, and vobcopy to fail. There are others, but they will fail as well.

have you tried k9copy - works great for me, and you can
select the subset of the titles you want to copy from the
disk (it does compression on its own, and produces a ready
to burn iso file).

anyone tried the 1.1 betas on amd64? or >=vamps-0.98?

I have. Works nicely.

I wrote my own bash script to do this. It uses lsdvd

Code: Select all

emerge lsdvd

so my script can ask me which title, and which of it's audio tracks, to rip, then uses mplayer

Code: Select all

emerge mplayer

to optionally preview it (to make sure, for example, that I'm not ripping an audio track that has the director's voiceover on it, etc. Then it just uses mplayer to dump that title/track to a .mpg file. The actual rip command looks like:

Code: Select all

mplayer dvd://1 -dvd-device /media/video/SOME_MOVIE -aid 128 -dumpstream -dumpfile /media/video/SOME_MOVIE.mpg

where:
dvd://1 is because I selected to rip track 01
/media/video/SOME_MOVIE can be /dev/dvd (my default - rip from an actual DVD) or can be a directory; in this case vobcopy -m wrote to /media/video/SOME_MOVIE dir.
-aid 128 is because I selected to rip audio track 0x80, which in this case was English 5.1 surround ac3 and I checked that it was not some voiceover thing.
/media/video/SOME_MOVIE.mpg is the destination file. Will contain mpeg2 video, ac3 audio.

Both lsdvd and mplayer can work with /dev/dvd (default) or with a directory. For lsdvd can just use the directory; eg

Code: Select all

lsdvd -x /media/video/SOME_MOVIE/

and, as I showed, mplayer can treat a directory as a DVD source using the -dvd-device parameter.

[pteppic]

Code: Select all

mplayer dvd://1 -dvd-device /media/video/SOME_MOVIE -aid 128 -dumpstream -dumpfile /media/video/SOME_MOVIE.mpg

mencoder will work the same way by replacing '-dumpstream -dumpfile' with '-ovc copy -oac copy -o ', and should dump at up to about 200 fps.
