How To add a delay to ogg files ?

[user]

I have a video stream and an audio stream, audio *.ogg

That audio stream should start about 4 seconds later than the video.

In Oggmux 1.0 I have no possibility to add a delay to the audio stream.



My workaround would be (as i have the original wave):

adding in headAC3he 0.23 frames, seconds to the wav-audio stream and encoding to ogg again....



But because the wave stream is very long, over 1 GB, and I have to do this procedure quite often (trial & error, because I want perfect sync between audio and video), it would be much easier, if I could add silence frames at the beginning to the existing ogg.

Then oggmux, and checking if sync.




So, is there a tool to add something to an ogg ?

you can try Cyrius OGM tools, there you can set an delay option for your ogg file .
get it here: http://cyrius.bunkus.org/

I have not found such a possibilty in text file explanations.

That program seems to be a commandline version, no GUI ?

Or via VirtualDub ?



I am disappointed, that I cannot use delay for the soundtracks (it is greyed out) in OggMux 0941...

well, then don't complain but CODE it.
We tried it but didn't succeed - direct show is a major pain in the ***.

I feel a bit insulted.

hey, don't feel insulted.
My English is not better to tell something else.

I wanted to say:

"Ich wunder mich, daß man delay Feld da sieht, aber es nicht nutzen kann..."

Well, technical problems, due to Ogg..

Everybody tells: "oh, Ogg is so good", but some basic tools are not working still, that is either a delay correction of ogg stream relative to the video stream,
or:
a program, to join ogg streams respectively adding silent frames at the beginning.

Or does soembopdy know a program, which does one of the 2 possibilities ?

you can use VirtualDubMod to mux your avi file and your ogg file(s)
with this software you can also add a delay in ms

it works well for me

yea, many thanks,

that program was already recommended in german forum of doom9.

There I have the possibility to add my 3 ogg audio streams, and to adjust for each stream an individual delay.

That's what I needed.

Are there any problems (sync etc...) known playing later these ogm's by BSplayer or so ?

@user:

Why don't you adjust delay with BeSweet while creating ogg?

[user]

@mikeson:

of course I could do it with HeadAC3he or Besweet, but:

as told above, the exact delay is unknown, so I have to do trial and error method.

For each trial , I don't want to encode the whole wave to ogg again...

With VDM there is a Muxing-Tool for ogg, 3 ogg streams + avi, and each ogg gets its own delay.

@user:

What is your source? I assume It is not DVD, so what is it?

Anyway you can open oggs (or source if supported) in SonicFoundry (or something like that) and you will see exact delay...

[user]

avi/picture source is 16:9 anamorphic with French and English sound stream (sync no problem :) ,
the difficult sound stream is German, taken from German version 4:3, and so there results an unknown delay due to other start credits at the beginning.

@user:

So as I've said, open all 3 files in SonicFoundry (accepts ogg) and compare where audio starts and you can measure delay for 3rd audio stream. ;)

@user
i know what your talking about, had the same problem while making an 3 language Escaflowne encode, with english and japanese from dvd and german soundtrack from MTV - TV captures ;o), but i have added the orginal japanese intro and outro too, soo i have a work of 1 hour only for audio cutting, joining and syncing for every episode, but thats how it is :D

i have set the delay with an wave editor and muxed avi+wav file to see if its sync, and after done the sync i encoded it to ogg.
