Joining 2 OGM files together?

[hacker_on_fire]

I know how to join 2 *.avi files together using VirtualDub. But how would you join 2 *.ogm files together?

Thanks

did you try virtualdubMOD?

^ what he said

using VDM you just append the second ogm as you would with avi's in regular VD

I did try VdubMod, but the 'Append AVI Segment' is not highlighted, so i cannot click on it.

[UncasMS]

did you actually OPEN the first file?

only then will you be able to append

alternatively you might use this command at ayour prompt:

copy /b movie1.ogg + movie2.ogg finalfile.ogg

concat(oggfile1, oggfile2) is a valid ogg file? no problems with headers..?

Yes, but to no avail.

When this is done, i get the final file. But when i try play it, only 'movie1.ogm' plays (so it doesn't carry on to 'movie2' like it should do). When i try scan through the finalfile it freezes. Also i tried open it in VirtualDubMod but get the error message 'invalid page' appears.

Sorry BoF, i do not understand. Could you explain further.

It was about UncasMS's alternative prompt command.. and I made a mistake with a french word, here is the good one:

append(ogm1, ogm2) is a valid ogm file?
with ogm1 and ogm2 2 valid ogm files.

[UncasMS]

apparently it doesnt work *g*

if vdmod or oggmerge dont do the job i'm running out of suggestions

[hacker_on_fire]

i tried oggmerger, but it only joins streams into one file. e.g. audio and video, like oggmux. Instead i want to append/join two files together.

Any other suggestions please?

Thanks

After consecutive attempts i have joined the two ogm files together using oggmerger.

What i did wrong before was i was trying to join two files where the video was encoded with the same codec but the audio was encoded using different (ogg and wav) codecs.
This resulted in a new file which was the same as the video with wav audio.

However i merged two files:
movie1: xvid, no audio (previously wav audio)
movie2: xvid, ogg

this ended in a new .ogm file with the video from both files merged, but with no audio. So using VDubMod i muxed the ogg audio(from movie 2) i wanted to keep again, but used a delay which was the length of movie1(roughly 3sec), so the audio was still in sync.

But as of course nothing goes according to plan. When i played my new merged file with audio, it would only start from the postion of the audio, which is 3 sec into the file, which means it doesn't play movie1 of the file, when i want it to play.

So does anybody have any suggestions?

P.S. sorry for such a long explaniation, its to help you understand everything.

Thanks

1) demux audio from movie2

2) append video of movie1 with movie2 WITHOUT audio

3) mux your audio (movie2) with oggmux applying the right delay (movie1 length)

4.1) that's wonderful, it works!
4.2) post a long explanation on what goes wrong

[hacker_on_fire]

Weird!

thanks for the quick reply.

But when i try to append movie1 and movie2 i get the following error message:

"Cannot append Segment: The Video streams have different sampling rates (23.97600 vs. 23.97600)"

Its weird, what should i do?

Thanks

p.s. i have attatched an image illustrating this.

"Cannot append Segment: The Video streams have different sampling rates (23.97600 vs. 23.97600)"


Do the following:

1) Load the first video-only file into VirtualDubMod

2) Set "Video" to "Direct Stream Copy"

3) From the "Video" dropdown menu, select "Framerate" - and select "Change framerate to" and enter 23.976000 (An extra 0)

4) Save with a new filename

5) Load (DO NOT "APPEND") the second video-only file - and check to make sure all of the above settings have remained the same

6) Save with a new filename

7) Close and re-open VirtualDubMod (cautionary)

8) Load the first NEW file and append the second NEW file

Let us knwo of your success ;>}

when i try i get the following error message:

"Failed to initialize Vorbis library to encode."

So what should i do next?

BTW all help is really really appreciated

Sorry for the late reply, its been a long weekend.

thanks setarip, your method of merging worked
All i gotta do now is to mux
