mkv audio not extracting right

[Halsafar]

Alright I had 2 mkv files. One was easy, it was a simple extract the audio using VirtualDubMod and the LameMp3 codec, then saving the video as a direct stream to avi, then multiplexing them together...Works, sounds just perfect


The second one, when opened in VirtualDubMod gives a warning about subtitles and variable framerate. Well they both gave variable framerate warnings. Well, the video on the 2nd one will not play in VirtualDubMod and when it extracts the audio it only gets 28min of a 46min file.

So I went and got the MKVtoolnix toolkit along with a GUI...
I used it to get the audio out as a Ogg.
I used the unrelated GUI to get the video out as a AVI.

I confirmed the avi and ogg files are correct and play fine.
So I open up virtual dub mod, open the avi, add the ogg to the stream list.
It plays completly out of sync, infact I can listen to the ogg file seperatly and it links up to the video fine, but if I use virtualdubmod it plays very funny...Like the audio skips a ton while the video plays onward.

Any assistance?
Or, maybe a better multiplexing program.

I think I got it, I had to download a ogg to wav converter.
Now the video and audio sync up just fine in VirtualDubMod, they have been multexed, and I should be burning soon.

Thanks.

If it really is VFR then it shouldn't play in sync as avi can't handle VFR.

I have a bunch more MKV to decode into a audio and avi.
I am a c++ programmer, games particularly....I have yet to explore the whole realm of video. So I am a newbie at this.

What would you suggest, assuming I can understand anything. I need to split some mkv and some ogg files up into the audio and avi so I can multex it into a full movie avi. It doesn't have to be avi, it can be mpeg or related, at least a windows registered codec format.

I can already do it myself but for the sake of quality....

A VFR MKV I would leave as mkv. I guess you could do it with mpg though. Encode the film stuff as 23.976fps with a 3:2 pulldown and the 29.97fps stuff as 29.97fps, that is assuming that it is a mix of 23.976 and 29.97fps.

If it plays in sync though it sounds like it wasn't really VFR.

Well I am watching the first I did 2night.
The bit I have watched of it was perfect.

I had to extract the avi and the ogg audio using Mktoolkit with the gui.
Conver the ogg to wav using Ogg2Wav
Mulplex the wav and avi together using VirtualDubMod
Burn using InterDvd Creator (i know terrible.....)

Now, if there is another easier way to get it onto a DVD without the conversions please inform me... My googlin and research has shown there is no way.

Anything that accepts input via dshow should convert it fine directly from the mkv.
