Can't demux with DGIndex, get error.

[2ZOD.COM]

I've demuxed the streams with MPEG Tools in TMPGEnc, but it doesn't register them correctly or some **** like that. I think there's a problem with the file headers. I think I need to rewrite them with a HEX editor or something like that. You might want to see this thread for what I'm trying to accomplish:
http://forum.doom9.org/showthread.php?s=&threadid=91830

I think there's a problem with the .vob files or something.

If I drag the vobs into power dvd they play fine, but the streams don't really register correctly or something... I really have no idea what the problem is.

There's no such thing as an MPEG2 file header.

You should load ALL the VOBs at once in DGIndex, and then do a "Save project and demux video". It should make a single M2V.

Maybe you are getting multiangle. How did you rip the VOBs?

Take a deep breath and tell us exactly what steps you went through from inserting the DVD to encountering your problem.

>If I drag the vobs into power dvd they play fine, but the streams
>don't really register correctly or something

This is incoherent. If they play fine what can you mean by "they don't register correctly"?

retrieved the vobs from the disk via dvd decryptor. I just updated to the newest version. The disk is also from 1997, so there's nothing really complicated or anything on the disk that would prevent this from working.

from there, the .vob files were all added into DGIndex just as you said, but when I demux them all it seems to only demux one of the files. The resulting video file is only 8 minutes long, when it should be about 140.

I can demux them all separately, but only the first one works error free. The second one, and on all give me a no closed GOP error, and say the first few frames may not extract correctly. No problem there, but when I try to merge them together (the only program I currently have to do this is the built in thing in TMPGenc called MPEG Tools) I get an error saying they are not valid mpeg2 streams.

(I can also demux them with MPEG Tools but for some reason the streams don't say the info like normal streams I've demuxed have said. There are pictures of this in the other post on this subject:
http://s91493280.onlinehome.us/DVD_Good.gif <- this is the first vob
http://s91493280.onlinehome.us/DVD_Problem.gif <- this is now the vobs 2 and on look
They demux fine, and the audio seems good, but the video can't be merged back together)

So can I close the GOP somehow then so I can merge them into one file.. or what?

Are you sure you set DVD Decrypter to IFO mode? That should rip the whole movie.

[neuron2]

When you load all the VOBs at once in DGIndex, can you see the whole movie's content when you move the slider from left to right? Set the slider at various points throughout and hit F6 to see if it plays OK at that point. Also, just hit F5 and tell me if it plays fine past the 8 minute mark, where you say demuxing stops.

Whoa - I guess your edit button shorted out, Don... ;)

Never thought to try IFO mode. I'm trying it right now. We'll see how it goes.

I'm actually trying to do the stream processing and demuxing with dvd decryptor.

This is a very basic dvd structure, before when I did file mode, I think there were only a few files that weren't selected.

UPDATE
Demux with DVD Decrypt didn't work, so I extracted via IFO in DVD Decrypt, and it plays just fine in DGIndex, except it goes really fast. Is that normal? Anyway, I'm demuxing right now, we'll see how that goes.

[Cyberia]

Good, glad it worked. Never demux with anything but DGIndex to guarantee sync.

Yes, PLAY is faster than normal speed.

Ciao

Woohoo all is well. Thanks again for the help. Never had such problems doing such simple things. Again, thanks!

edit
Now the question is... can I make the volume in an .ac3 file louder without decoding to wav and reencoding back to .ac3?

The video I demuxed is about 4.2gb and I already extracted the audio and made it louder, but that file alone is about 1gb. It's raw wave, and I could convert back to .ac3 or mpeg, but it would be sweet if I wouldn't have to decode increase volume then encode.

Please take audio questions to the audio forum. You'll get much better support there. Thanks.

Nice job, Cyberia, on catching the rip problem!

Thanks, I'll be here all week.

Nice said, to demux always with DGIndex. Its true, it demuxes perfectly.
Äh... since when it can perform also this step with this finest developed tool?
The many hundreds of my (tv) streams also wanted to be demuxed.
I must honestly apologize that I was using ProjectX instead and sometimes,
to say the truth, I do use it again.
:) ;) :)

In facts, some streams are becoming too much of industrial strength treatment in this ProjectX Tool
and a lot of hours are gone finding out that there is no satisfying result with these files.

Since a few weeks DGIndex also demuxes streams and so I let them run through it.
What to say, they came out after a few minutes in a perfect syncron shape. So to say: DGIndex-like !
Does that mean, that the Industrial norm is not so extrem striktly at work here.
Or is it only profund geniality ?

Thanx for this wonderful development

DGIndex works great on clean streams. But once you start getting much data corruption, it can fail pretty spectacularly. I'm contemplating a stream preprocessor to repair such things, but on the other hand I don't want to just recreate a tool such as ProjectX, if it is adequate for the purpose.

But first, MPEG1 support is on the burner.

That could mean that a very exclusive and in general expensive feature
with long-time working to create it will be implemented then in DGIndex.

Hard to find such a decision-making repairing tool that not only cuts out
the disturbing for resulting in (perfect) synchronous streams.

What way it will be inviting us to use it?
- it could recreate/create new what was there before and goes for rebuilding...
- it could use matrixes for defined problem-fields...
- maybe you decide to cut the whole stream in pieces ending up back to industrial standards...
- the "insert intelligent dummy" thing...
- ...

For sure is, that we use it :)

Thanx
