OGG Vorbis and Nandub: preload and interleave?

[marc_albero]

I have looked in the forums for some values to use in the preload/interleave settings of Nandub, in order to a mux DivX video stream with an OGG audio stream. I haven't found any. Anybody can help?

I know that everybody muxes OGGs using OggMux, but Nandub seems to be more complete, since it allows to set preload/interleave values, am I right? What values uses OggMux? Can they be set by the user?

Thanx

no. sorry, you can't mux vorbis into an avi countainer, you have to use an ogg container.
nandub in fact has an option to mux vorbis into avi, but it won't work properly.

Thank you for the hint, but I'd like to read more about that AVI-Vorbis incompatiility. Have you some link addressing that issue?

By the way: in OGGMux, when you introduce an audio stream, there are two input boxes, one for delay and another for quality. They are always disabled, even when the input audio stream is OGG Vorbis audio. So no delay can be introduced from the GUI. Is there any means to use them? I want to fine-tune the delay of the audio stream, and it would be much faster if I could insert the delay after encoding to Vorbis and before remuxing with OGGMux.

The method I have to use now is to encode to OGG from the source (WAV converted from 25fps to 23.976fps) using HeadAC3he. Before encoding, HeadAC3he allows to insert the delay. After encoding, I mux the streams and test for synchronicity. Too much time, as you may guess.

Is there any utility or method to synchronize OGM files with Vorbis audio streams, as AVIInfo does for AVIs?

Thanks

Quality is for encoding wavs while muxing. I think (never tried it) delay works the same way, I know thers no way to introduce it atm for already compressed vorbis audio.

no, sorry. i read about this issue on this forum only. if i remember correctly, it is because vorbis is true vbr which avi has problems with. u may run into sync or seeking probs.

AFAIK functionality behind the two disabled input boxes is not implemented yet. koepi may tell you more about it.

AVI can "not" handle VBR audio period. Some people on some systems get VBR MP3 to work "ok". But because the AVI does not support VBR audio it behaves/plays very differently from system to system. It is worse with Vorbis because You can't just put a vorbis stream in an AVI. The Vorbis stream has to be in an OGG and then put that in the AVI. But by doing that there is no way to seek. You can get synch. But you always have to watch a movie from the start to the end nonstop. Ditch the AVI and put both the video and audio in the OGG.

BTW the link everyone was looking for and could not remember was the news page at Avery's site. Since he upgraded his layout I don't see it any more though.

look here for me is working, it's google's cache for that page:
argh... Adding that url wont work on this forum.

I've cleaned the page and made a zip (wait the attachment).
Since this page contains intresting things, I hope could be usefull.
(I was searching it some time ago)

Doh I shoulda thought of that! Damn cache. :)
