Vodei Multimedia Processor and how to bypass it

[WeMustUnite]

For those of you who have chanced upon those Vodei MP protected avi movie files and not wishing to be blackmailed into installing their insidious player software, the solution can be found here:

http://www.bevewyvewyquiet.150m.com/


This blackmail scheme targets mainly BitTorrent users, but can also affect other P2P users when those protected avi's are then shared on other networks.

Seems like the link is dead.

No matter. The info on that page is reproduced here:

Vodei 1.09 Multimedia Processor

This is just a silly little wrapper "codec" for avi content.


Currently there are two solutions to getting unrestricted playback access to the avi.
If the first solution does not work, then temporarily install the "codec" and try the second solution.




1. NOBBLE THE AVI FILE


Open the avi in a hex editor (eg UltraEdit) and do a search for the text string "STRD", and nobble these four bytes with zeros.

For example:

53 52 54 44 ; STRD --------> Before

00 00 00 00 --------> After





2. NOBBLE THE CODEC ITSELF


VodeiMPAVI.ax (618,496 bytes. md5sum 946e1c60cb4556717664d6b4262987b4)

Open "VodeiMPAVI.ax" in a hex editor (eg UltraEdit) and jump to offset 19804h. Then nobble four bytes:

75 07 32 C0 --------> Before

90 90 B0 01 --------> After





Once you have unrestricted playback access to the VodeiMPAVI avi file, you should demux it and then remux it to a standard avi file.

You can use Graphedit to demux the video and audio streams:

VIDEO
DirectShow Filters
*File Source (Async) ---> browse to and open the VodeiMPAVI avi file
*Vodei Multimedia Processor Splitter
*AVI Mux
*File Writer ---> save to an avi file

AUDIO
DirectShow Filters
*File Source (Async)
*Vodei Multimedia Processor Splitter
*Dump ---> save to an audio file (mp3, ac3, etc)


All these filters are placed in the same filter graph.

The connections are very easy to understand and do.

Click the play button and wait a few seconds...


Now remux the two files using VirtualDubMod in "Direct stream copy" mode.

The resulting avi will be smaller (hence uploading/downloading it will be quicker), and your avi player will load it faster too.

Kudos must go to those two benevolent people who originally put forward the solutions above (you know who you are).

It's good to know that there are such people in this world.

Thanks Dude!!!

[Guest]

I'm new to this GraphEdit app.

Where do I get the following fiulters from (I couldn't find them):

VIDEO
*Vodei Multimedia Processor Splitter
*File Writer ---> save to an avi file

AUDIO
DirectShow Filters
*Vodei Multimedia Processor Splitter
*Dump ---> save to an audio file (mp3, ac3, etc)


Any help would be greatly appreciated.

Thanks

Create a disposable email account and I will upload it to you.

Post the login details here.


Btw, if the keyframe index is corrupted during the demuxing process (you'll see it as playback artefacts when random seeking the movie), then you can use VDM or DivFix to rebuild/derive a new keyframe index.

Thanks WeMustUnite

Any suggestions on a disposable email id? I don't want to post my used email ids on the web - but I don't have much experience with disposable ones either.

Sorry for all the requests for help.

[Guest]

Also do I need to actually get the vodei codec from their site because I'm wary of going there as my suspicious nature is sure that they're monitoring stuff.

Is there anything else I need to get for the vodei -> normal avi transformation process?

I tried this (nice simple instructions by the way - thanks) but the nobbled AVI still showed the vodei screen when I tried to play it.

[WeMustUnite]

A disposable email address means a free web email account that you only need to use once ie hotmail, yahoo, etc.

If the first method doesn't work, then try the second - for that you will need to install the vodei software.

Go here and login to get it:

http://www.mail.com/scripts/common/inde ... =1&lang=us

member: aardvark@comic.com
password: 12345678

and download the following archived file:

graphedit011008.rar

md5 checksum = 50cb135eeea8c8697cad8d4e121833c2

Use a md5 checksum utility to verify that the above file has not been tampered with.

Extract the contents of the rar archive using WinRAR, password = vodei109sucks

Don't forget to log out of the email account.

Now, follow the instructions in my second post above.

[Guest]

Thanks very much WeMustUnite. You're a star!!!

I've downloaded the file so you can remove the email id info from the thread.

I just have one problem - sorry

Using VirtualDubMod - I can't seem to get it to find the MP3 audio file so it renders it as a silent video clip.

I used Direct stream copy and that was all fine but I didn't know where to make it look for the audio file. The app's help file didn't help much.

I tried using VirtualDub but that wouldn't accept MP3s.

I'm probably being a total moron but if you could help on the Virtualdubmod MUX options that would be great.

Thanks again

[WeMustUnite]

In VirtulDubMod, click:

Streams > Stream list > Add

then, navigate to and select the MP3 audio file.

Now "Save As..." in direct stream copy mode.


If you need to fix the keyframe index, then put a tick in the "Ask for extended options after this dialog" box when you go to open the file; followed by "Re-derive keyframe flags".

Btw, I made up the email login details using imaginary registration details, so there is no need to delete it. Remember, it's disposable. Anyone may dowload the rar archive, but they must doublecheck the md5 checksum.

[WeMustUnite]

Oh yeah, if VDM mentions anything about VBR MP3, click the No button (you don't want to rewrite the VBR MP3 header info).

[Guest]

Thanks for all the help WeMustUnite

It worked a treat and I've now happily uninstalled Vodei from my PC. It was on there for just a few hours for me to do the conversions.

One question - is there any problem with leaving the .ax files that the batch file register.bat (in the graphedit folder) added to my PC?

Thanks again - you're a star !!

[Vladd44]

guest,

Care to screen capture the procedure? Or email me a meg or so of the beginning of the video file so I can duplicate it?

guest,

Which procedure do you mean?

I'm afraid I can't send you the Vodei encoded clips any more as I deleted them as soon as I made them into normal files.

[Vladd44]

heh.

then do you have a torrent of the file?

I would like to be able to recreate the scenario, but I cant get screen captures of it unless I have the product.

I only managed to find one of the torrents as I've been holding onto a bunch of these Vodei files hoping for a solution for a few months.

This is the only one I could find: http://www.torrentportal.com/torrents-d ... p?id=44571

Hope this helps.

I must be an idiot,

With XVI32:
I cant find a STRD string in the avi file
I cant find 19804h in the ax file

With GraphEdt:
I cant find *Vodei Multimedia Processor Splitter
I cant find *Dump

I tried to substitute *Vodei MP Avi Splitter for *Vodei Multimedia Processor Splitter but im guessing that is wrong because i hit play and nothing happens. What am i doing wrong?

[WeMustUnite]

@655321

Please read all posts from the top again. If the STRD method doesn't work, try the second method. Download the graphedit011008.rar package from the email address given above.

GraphEdit, the Dump filter, and Vodei 109 are included in the graphedit011008.rar package. You'll need to run the "register.bat" (inside the GraphEdit folder) to install some *.ax audio/video decoder filters, or "register2.bat" to install just the "Dump.ax" filter.

Look at the included jpg's to see how to chain/join filters in GraphEdit. To create the links simply click and drag one output node of a filter to an input node of another filter.


You can safely leave the *.ax filters installed on your system, or you can remove them as follows:

regsvr32 /u /s "path\to\filter\FilterName.ax"

To make it easier, create a batch file in the same folder as where the *.ax files are located:

----------------------RemoveFilter.bat------------------

regsvr32 /u /s FilterName1.ax
regsvr32 /u /s FilterName2.ax
regsvr32 /u /s FilterName3.ax
...

-----------------------------------------------------------

Well how hard can it be.

I edited the VodeiMPAVI.ax with ultraedit as descriped above
copied the edited VodeiMPAVI.ax to the system32 folder
added the following line to register.bat from graphedit (regsvr32 VodeiMPAVI.ax /s)
executed the modified register.bat
And now any player on your pc will show what inside the vodei "wrapper"
cool ha'

[Nitpicker]

Just a little note that may explain why some are having problems with finding STRD. The listed hex "53 52 54 44" is SRTD not STRD.
