Joining AC3 streams

mattbag · 12th February 2003, 09:19

Hi all!
As I use DVDauthoring IFOedit functionality, I need to have ONE big M2V file and ONE big AC3 file...

To merge some M2V files into one, I use the dos command :
COPY /B "X1.M2V"+"X2.M2V"+...+"Xn.M2V" "RESULT.M2V" --> OK, no pb

But what about AC3 files? It seems that I can't use this DOS command again because of the AC3 headers in files, So does anybody know how can I definetly merge AC3 files into one?

In Standard DVD, I obtain directly one 1C3 because, there is only one PGC but know I'm working on a DVD movie which contains several PCGs...

Thanks a lot guys!
Mattbag

If you care about headers, then you must not use this method for any kind of MPEG video file either!
What you create is a file with broken timestamps.

Hi,
I want to merge 2 AC3 streams, but i dont know how.I maked a Join.lst with the following content:
C:\Programme\Ripping\DVD Decrypter\VIDEO_TS 2\VTS_01_1 - 0x81 - Audio - AC3 - 6ch - 48kHz - DRC - Deutsch - DELAY -80ms 2.AC3
C:\Programme\Ripping\DVD Decrypter\VIDEO_TS 2\VTS_01_1 - 0x81 - Audio - AC3 - 6ch - 48kHz - DRC - Deutsch - DELAY -80ms.AC3

And then i maked connection (i dont know the right word in german it is in windows "Verknüpfung", but i think another word is icon)
with the following content:
C:\Programme\Ripping\BeSweet\BeSweet.exe -core( -input join.lst -output stream.ac3 -payload )

But when i start it, it doesn´t work. The Output file is a 0 byte File!
Can someone help me and tell me how to merge two ac3 files?
p.s. Vobinput.dll is in the besweet directory.
p.s.2 Iam german and my english is not the best, i hope everybody understand what i mean!

You can try a little tool named filemerger http://fysx.acwu.com/Programs/Downlo...r-01-07-14.zip

or an alternative that has the same name

http://home.planet.nl/~doesw008/file...2.2-redist.zip

don't know which is better, cause both seem to be very equal .

Drag and drop the files you need to merge and press merge or Go!. The output is good, you almost don't notice it.

Und nochma auf deutsch

Nimm eines der Tools, das zweite hab ich eben nebenbei gefunden, beide sind irgendwie ziemlich ähnlich. Einfach reinschieben die teilen und dann mergen. Das ergebnis ist ganz gut, also man merkt fast nichts. Kannst damit eigentlich fast alles zusammenfügen.

(Verknüpfung = Link *g*)

Th3-S4int · 1st August 2003, 12:19

Many thanks to you. The second tool works well.(i didnt test the first,because on the site he write that only mpeg can be merged)

brute · 1st August 2003, 13:12

I merged AC3 and AVI files successfully with it, bit if the second works well, it's okk, too

Th3-S4int · 2nd August 2003, 12:33

i have found a problem: when you merge 2 ogg sound files vdubmod cant put the new file in a ogm file (he only put the first part of the old file in). now i test if ac3 work better. i think the problem is the header!

m1a2lt · 3rd August 2003, 06:24

Try using HeadAC3he and it will repost the header for the .ac3 files. Used to have the same problem with filemerger until I started using it.

bond · 3rd August 2003, 10:25

you can also try good old dos commandline:

Code:

copy /b "c:\input1.ac3"+"c:\input2.ac3" "c:\output.ac3"

it works, but dunno if there are header issues!?

Th3-S4int · 3rd August 2003, 12:55

when i merge ac3 and then encode it to ogg vorbis with besweet i have no problems!but i read somewhere that ogg vorbis has a more complex header like mp3 and that why i think that file merger cant merge ogg 100% right

dvd_master · 26th October 2003, 21:07

None of the FAQs help, since I SUCK at command lines. Is there an interface or program with a gui that can just merge the two files togather?

I experimented (badly) with BeSweet with no such luck. Or if anyone can tell me the exact lines I would use to join these two files...

prt1ENG.ac3 and
prt2ENG.ac3

They're both in the root of my drive "F". Anyone?

dvd_master · 29th October 2003, 00:39

ergh, I knew if I posted under another thread no one would answer, that's why I made it a new topic! Whhyyyyyy was it moved!!!!!1

KpeX · 29th October 2003, 00:48

Try not to get aggravated, and try this:

First, open up notepad, and type the following two lines:

Code:

f:\prt1ENG.ac3
f:\prt2ENG.ac3

Then save the file as 'filename.lst' in your f drive as well. (make sure to change the file type to 'all files' when saving).

Then run besweet using the following commandline:

Code:

besweet -core ( -input "f:\filename.lst" -payload -output "f:\output.ac3" )

hth,

thx

KpeX · 11th November 2003, 04:28

What are you asking? Your question is unclear.

xixi2000 · 11th November 2003, 06:36

use BeSweet
BeSweet.exe -core( -input 1.ac3 2.ac3 -output stream.ac3 -payload )
but output stream.ac3=1.ac3
why?

KpeX · 11th November 2003, 06:50

See this http://forum.doom9.org/showthread.ph...976#post391976

and Q 7 here

Hope this helps,

xixi2000 · 11th November 2003, 07:42

e:\BeSweetv1.5b23\besweet.exe -core ( -input "e:\filename.lst" -payload -output "e:\output.ac3" )

e:\BeSweetv1.4\besweet.exe -core ( -input "e:\filename.lst" -payload -output "e:\output.ac3" )

Do not works
