vob2audio crashes

[iparout]

Hi.

I have been using vob2audio for couple years now to create WAV files out of the DVD vobs, however yesterday a strange problem occured. I upgraded my 2,0 GHz Northwood with a 2.53 GHz Northwood and when I tried to work with vob2audio, the program crashes. To be more precise, after loading the .lst file and naming the output .wav as I used to, when I hit on START the program crashes.

The weirdest of all is that when I re-installed my previous processor (2.0A Northwood) vob2audio worked fine. Is it probably an incompatibility between the program and my new CPU ?

I am very satissfied by the program cause it creates loud WAV files and I don't want to stop using it. If anyone needs the error report that Windows creates after the crash, say so and I will post it.

In case the problem cannot be solved, I have heard that vob2audio is a small version of Graphedit. I have downloaded Graphedit and I would appreciate it if someone told me how to use it in order to create WAVs that are the same as the ones that vob2audio outputs.

Thanks in advance for any help.

when i came across the ogg vorbis audio format i quit using vob2audio.

maybe you should give ogg a try it is most definitely better than mp3!

of course the sound is balanced and powerful if you use proper settings in besweet/gui:

i prefer one different setting to what i wrote in my guide, though:

in the very first screenshot down left in number 3.
i use pregain ~8db

First of all, thanks for your help. Somehow, I knew that you'd be the one answering my question... Anyways, I have heard many good things about Ogg Vorbis audio but I'm still very reluctant on changing my all-time-favorite audio format (=mp3).

I will give Ogg Vorbis a try of course, cause I may in fact like it but I would still appreciate it if someone told me how to use Graphedit in order to create WAVs similar to the ones that are extracted with Vob2audio or at least give me any thought on why Vob2audio crashes on my PC.

P.S. : Since I am seriously thinking of trying Ogg Vorbis audio, I suppose I should encode the audio seperately and then multiplex it with the video stream. The question is, what do I choose in Interleave Overhead in GKnot in order for the program to calculate the bitrate correcly ?

[UncasMS]

vob2audio actually uses graphedit routines
thus you might end up with the same problems when using graphedit.

if you want mp3 (dont be reluctant btw and give ogg a try for your future conversions - it is definitely worth the change) you could use the very same routine i described in that guide above for ogg but simply use mp3 as output format.

besweet/gui will hopefully run stable on your machine

In the guide you posted in the above post, your output file is an .ogm and not an .avi. I don't want to change to Ogg Media format cause it isn't very popular yet and it's not supported by GKnot. However, if I could use Ogg audio and .avi file, that would be good. That's why I would like to know how to make GKnot take into consideration the overhead of the Ogg audio file, in order to calculate the movie bitrate correctly.

[UncasMS]

if I could use Ogg audio and .avi file, that would be good

dont even think about it.

stick to mp3/avi or go for the whole nine yards.

why care for so called popularity?
only because others are not willing to use better formats and enjoy higher quality?

ogm needs only some directshow filters to be installed. they are not even 0.5mb in size and after installing them every player will hanlde ogm.

no need to stick to avi if you ask me.

I am thinking very seriously about changing to the Ogg media format because of the Ogg Vorbis audio and the capability to include chapters in the video. I've been following your advice from the very beginning of my DivX encoding hobby and all my movies are awesome so far. I'll now try your new suggestion.

Two questions though :

1) Which tool do you use to create the OGG files ? DVDtoOgm or DVX ? And why should I prefer one of them over the other ?

2) Can removable .srt subtitles be played with DirectVobSub when using the .ogm container ?

[UncasMS]

i use DVX (click on the pic in my signature) für the VIDEO part.

for the creation of the audiostreams in ogg vorbis format i prefer besweet/gui.

subtitles work fine with directvobsub for me.
i have done more than one bilingual encoding with 2 subtitle streams in srt format.

Ok. Thanks a lot for your help. I will try the OGM format sometime next week when I'll get access to my PC again. I'll post my opinions here.

One last thing : I have downloaded BeSweet v.1.5 b.17 from DSPGuru's site and the .zip file does not contain the azid.dll. Can I use the azid.dll from the latest stavle version (v. 1.4) ?

[UncasMS]

install the full version 1.4 and overwrite it with the newer files

[iparout]

OK. I will do that. Thanks for all the help.

OK, I am trying out the Ogg Vorbis audio. I got one question : You said that you use a Pregain of ~8 dB. How are you sure that the amplification of the audio by 8 dB won't cause clipping ? There are some DVD whose audio is already normalized. If I amplify that audio by 8 dB then serious clipping will occur.

[UncasMS]

How are you sure

i'm not ...... but give it a try

[iparout]

I just did ! The audio is indeed loud and after scrolling quickly through some of its parts it doesn't have any problem. However I can't live with the doubt that clipping *MAY* occur in some parts of it, so I'll just normalize it without applying any Gain to it.

BTW, I have tried DVX and it's a real pain. It is quite slow and a bit too complicated for my taste. I think I'll stick with GKnot.

My thought is this : I will use GKnot to create the video in DivX 5.05 Pro and then use VDubMod to manually mux it with the Ogg audio I have previously created. Will this result in a valid OGM file or not ?

[UncasMS]

you can create your file with any tool you prefer and afterwards or befor create an ogg (or more) audio stream and mux afterwards with vd_MOD - that's what i prefer to do.

btw dvx might be hard to handle/set up (cant judge -once you get the hang of it) but it definitely isnt SLOW.

it uses avisynth + vd/vd_mod for the transcoding part and that's identical to what gk does.

i prefer its options and support but taste is different of course.

when you create OGM files, maybe adding chapter information is a lovely thing!?

how this could be done is described in my DVX guide - click my picture for more.
