Demux divx with ogg audio? Help!

[hazmat42]

I recently downloaded "The Others", and it is a divx movie with ogg vorbis
audio. I'm trying to convert the audio so that I can load it into Vdub and eventually into TMPGenc. Baldrick recently posted a guide to reencode an avi/ogg to avi/mp3 using Graphedit. However, when I tried to do this, I got an error message saying that "the graph could not change state. The sample start time is after the sample end time". I posted this problem at the end of that guide, but I thought it would be a good idea to start a new thread to make sure I got a definitive answer to this problem (if there is one).

Does anyone know enough about Graphedit to solve this problem? Does anyone know a site where I can get more information on how to use Graphedit? Is there another way to demux an avi/ogg? If I can just demux, converting the audio stream will be a piece of cake. Yes, I do have all of the proper codecs installed, including the Ogg DS filters. No, the movie won't load into Vdub or TMPGenc at all. Can anyone help me?

I followed basically the method in the guide, and ran into the same error message. So I set things up again, and deleted all the audio boxes to produce an avi without sound. I set it up again for the audio, but altered things to produce an uncompressed wav rather than an mp3 (which had caused others sync problems). I then fed the avi and wav into TMPGENc to produce an in-sync VCD.

For the video, keep the top 2 boxes as in the guide, and add avi mux and filewriter to the ogg splitter.

For the audio, top 2 boxes as before, and add Vorbis decompressor, wav dest and filewriter to the ogg splitter. Just choose an avi extension for the created file in the first part, and a wav extension in the second.

http://nickyguides.digital-digest.com/audio-extract.htm should give you some more ideas about how to handle Graphedit. HTH 8)

I gave your suggestions a try, and the video demux worked perferctly. However, the audio demux created a massive 2.3 GB uncompressed audio file which I did name with the .wav extension, and when I tried to play it in Winamp, I got an error message saying "Cannot find destination format" (whatever that means). I tried to load the .wav file in TMPGenc, but that program didn't accept it either. I even tried to open the file in WMP 8, and that program said there was a buffer problem.

Needless to say, I don't know what went wrong or how to fix it. I really don't even know where to begin.

I'm thinking that either

a) I need some other file writer or

b) I need to add some other audio compressor.

Any comments or suggestions would be greatly appreciated, especially if someone knows how to demux the ogg stream and convert it to MP3. I don't know which filter I need to go between the MP3 compressor and the file writer. You apparently can't hook them up directly because Graphedit tells you a filter was missing.

I would skip the mp3 stage whilst extracting the audio. Input the wav (when you get it!) directly into TMPGEnc as the audio input. TMPGEnc works best with an uncompressed source.

After I posted my last reply, I downloaded an ogm sample and went through the process again. You need the ogm output and ogg splitter which you should get (with the boxes you don't want) when you*Render Media File*. To these 2 you need to add Vorbis decompressor, wav dest and Filewriter.

So you have ogm --> ogg splitter(audio1) --> Vorbis decompressor --> wav dest --> filewriter.

Join them up, and go! The wav file will be big - typically over 1 GB, and it should play perfectly in Winamp. 8)

I did do exactly what you told me the first time, and just to double check, I did it again with the following:

render media file > ogg splitter (audio) > vorbis decoder > wav dest > file writer

I got the exact same result as I described in my previous post, i. e. a massive audio file that would not play in Winamp with the error message "couldn't find destination format"

I'm beginning to think that I have a corrupt file or something, because what you describe should work. What baldrick described originally (to convert to mp3) should work. I'm at my wits end!

P.S. Is there any way I can just save the ogg vorbis audio stream without decoding it to another format? I tried the others > ogg splitter > file writer, and Graphedit said ogg splitter and file writer couldn't be connected (presumably without another filter).

[banjazzer]

I don't think so, because Graphedit is the only prog I've found will load it! I think they put these ogm files together using Graphedit, so it would make sense to use it to deconstruct the ogm. What might be worthwhile would be to download an ogm sample. They seem to get posted frequently in alt.binaries.monter-movies. Failing that, you could do what I did before using Graphedit to extract the sound. It's not elegant, but it works.

Are you sure you have the ogg codec thingies installed? ie can you get sound with something like Zoom player?

So long as you can play the ogm with sound, Total Recorder will record it as a wav. You can then input this wav into TMPGEnc. There are 2 major problems using this method.

1. It takes as long as the movie lasts to record the wav.
2. You invariably have to re-sync the audio.

Isn't life simple with DivX and mp3 audio?

Well, I finally went back to the drawing board and started thinking to my self: "Why isn't this working when it should be working?" I do have all the proper codecs installed (twice now), and to be sure, I can play ogm and ogg vorbis music on WMP 8 and Winamp. Even the Winamp vorbis plug-in works properly.

So, when something isn't working like it should, I point to the usual suspect: Windows XP. I burned the movie, the Ogg Vorbis DS filters pack, and the Graphedit program and transfered them all to my old computer, which uses Windows 98. And, that's right, you guessed it, everything worked perfectly. I converted the ogg vorbis audio stream to wav, loaded it and the video stream into TMPGenc, and created a short vcd sample. No problem. Now all I have to do is cut the massive file in half (with GoldWave in case anyone is wondering), burn both halves, and tranfer it to the new computer for converting to vcd.

(Enter rant on Windows XP):

So the moral to the story is Windows XP sucks. Maybe there is a bug somewhere in WMP or the Direct Show architexture I have on my most recent computer, but I am constantly running into problems with XP. I remember trying to install a removable harddrive on XP using drivers from my old computer, and XP told me I had compatibiliy problems. Since I couldn't find an updated driver, I contacted customer service, and they told me that XP "was very territorial and didn't like any programs not specifically tailored for XP". No kidding. I used to tranfer programs from my even older Windows 95 computer to 98 with no problems. XP is truly the type of quality product I would expect from Micro$oft (sarcasm alert).

But hey, I could be wrong. At least I solved my problem. As I said in my first post, I posted a reply in Baldrick's guide about problems with Graphedit. I'm wondering if they are Windows XP users too.

Anyway, problem solved. Someone needs to write an ogg vorbis plug-in for Virtualdub. I'm done

Glad you got sorted. I've had a copy of XP almost since it came out. However, with the 2 PCs that I use most, both are running 98SE!
