virtualdubmod crashed out of bounds error module divx

[themods]

hi, i've just installed divx 6, tried to convert a xvid film to divx6 and as soon as i pick compression and click ok, it crashes before i can start to dub.

it only happens when i pick divx6 i've tried the xvid codec and that works fine.

Anyone know how to fix this?

crash report listed this: -

Crash reason: Access Violation

Crash context:
An out-of-bounds memory access (access violation) occurred in module 'DivX'...

...while passing start message to video compressor (VideoSequenceCompressor.cpp:284).

[guns1inger]

Which version of Divx 6 ?
Do you have any codec packs installed ?

[themods]

i did have but i uninstalled everything, now i just have divx and the xvid codec installed

[themods]

i've also tried updating to the latest divx package, and it throws out a new error, instead of module divX it's module dpl100

[jagabo]

dpl100.dll looks like it is part of Divx's licence manager. Why don't you just uninstall Divx and encode with Xvid. They are both MPEG4 ASP encoders. If you need the Divx fourcc go to Xvid's "Other Options" dialog and set the fourcc to DX50.

[themods]

i wanted divx6 because i'm converted blue ray .ts files to a dual layer or dvd size disc keeping the screen sizes from 720p to 1080p.

I thought divx6 offered better compression and bitrates for hd films, unless xvid is just as good i dunno.

[guns1inger]

To play back on what ?

Personally I would use H264 instead. Better quality than Divx unless you are going to use Divx7.

[jagabo]

Divx6 and Xvid are essentially the same thing. Divx7 includes h.264 encoding (which is better than Divx6/Xvid) but you have to use their crappy Divx Converter program to get it.

[themods]

usually i could use whatever if its played off pc, but for playing off my xbox 360, and a media player connected to my hd tv, they only seem to have limited support for codecs.

i.e. the mediaplayer box (AVI:WMV9, WMV: WMV9,MS-MPEG4v3/DivX/Xvid no GMC/QPEL option).
MP4:MPEG4 Video

xbox 360 - is a bit more tricky - usually just end up streaming and transcode to wmv on the fly

[themods]

Divx6 and Xvid are essentially the same thing. Divx7 includes h.264 encoding (which is better than Divx6/Xvid) but you have to use their crappy Divx Converter program to get it.

Doesn't virutualdub reconise the codec and able to recompress with it?

[jagabo]

Unless they've added it in the last month or so Divx7 does not install a VFW h.264 encoder. I don't think it even installs a Directshow h.264 encoder. The Divx Converter program appears to have its own internal h.264 encoder. They seem to have done as little as possible to integrate Mainconcept's h.264 encoder into Divx Converter. You don't get very much control over the encoder either. Divx7 continues to install the Divx6 ASP encoder for VFW.

[DarrellS]

I downloaded and installed the DivX H.264 Codec CLI a couple of months ago that I found on the internet which allowed me to choose my own encode settings but it only worked for a week or two and then expired. Can't find a newer BETA release so it's back to x.264 instead of H.264 with MeGUI.

I used a frontend for the DivX H.264 Codec CLI called WhisX to encode the H.264 files.

Don't know it DivX will release the H.264 encoder in a future build or if they will sell it seperately. The builtin encoder in DivX7 with the low bitrates sux.

[jagabo]

Oh yeah, I had forgotten Divx has a CLI based h.264 encoder.

[themods]

i know is gone a little of topic, but does anyone know what causes the out of bounds error, from what i've read it's the divx codec causing the problem and not virtualdub.

anyone know any fixes apart from using a different codec format.

[poisondeathray]

DarrellS - If sign in you can download a beta 1 CLI here: http://labs.divx.com/node/6536

(not that there is much to be excited about)

But their free DivX h.264 decoder is excellent. Higher fps than ffdshow-mt, or coreavc pro on a quad. It can even decode some broken streams that ffdshow cannot.

Sorry for the OT

This doesn't answer you crash question, but if you are going xvid=>divx, you can try a fourcc changer , it will often work, because the stream contents are not that much different for divx vs xvid. e.g. try nic's fourcc changer. This way there is no wasted time re-encoding or quality lost, only the header info is changed

I'll give that a try, see if i get any better results

[jagabo]

Regarding crashes in Divx: sometimes a corrupt file can cause a decoder to crash. Some decoders handle some errors better than others so switching to a different decoder can sometimes get around the problem. And although Divx and Xvid are mostly interchangeable you occasionally find a video created by a specific version that had a bug or some other incompatibility.

Your description of the crash (right after selecting an output codec) doesn't sound related to this though.

[SATSOK]

a bit late but i have the same crashes frequently.
the same error report
An out-of-bounds memory access (access violation) occurred in module 'DivX' ..etc..etc..

but let me explain the circumstances.
my system is an overclocked Q6600@3800MHz which is rock stable,it had passes endless hours of testing with prime95 and OCCT without any errors and is been working hard for monthes already with none BSOD ever and none other software error.

why i say all of this? simple,the virtualdub crash occurs only at 3800MHz and very rarely,i have encoded hundreds of movies so it has absolutely nothing to do with bad frames,bad videos etc..

when i roll back the cpu`s frequency to 3600MHz no more crashes at all
NEVER,WITH ANY VIDEOS.

so ,what ever has been writen in this topic about possible reasons,about problematic codecs or bad frames are all bullshit.

truth is that virtualdub has a small stability problem which appears in some systems more frequently than others.

Then it sounds like your system is not "rock stable" at 3.8 GHz. Although it's possible there is a software race condition that causes the Divx decoder or VirtualDUb to crash its much more likely that there is a particular sequence of instructions that simply doesn't work with your system overclocked 3.8 GHz. It's simply not possible to exercise all possible sequences of instructions and data patterns in a stress test program.

so ,what ever has been writen in this topic about possible reasons,about problematic codecs or bad frames are all bullshit.

VirtualDub definitely has its share of bugs, especially the beta releases. But that doesn't rule out other possible problems.

alright people I just got myself
The.Crazies.1973.iNTERNAL.DVDRiP.x264-tehPARADOX
cause, I heard there's a remake, and I saw the trailer online late late lastnight.

So, i decided to get the movie
Keep in mind that I also. got
The Crazies (1973) DVDRIP

now, the first file that I listed it comes in a whopping 1.72 GB
now, the second file i listed come in @ 677 MB

But, I can def tell the quality, and I was honestly going to give up trying to convert the .mkv with this VDMOD. but I rather have the quality that the file gives me, but I get this error that's pissing me off. So, I need some help wit this.

"An out-of-bounds memory access (access violation) occurred in module 'VirtualDubMod'."

That's what I get, any reason to why I'm getting this error?

I clicked on "Advance" and it tells me

Crash Reason: Access Violation.

WTF is that?

I also included as you can see the crash log, maybe you can figure something out as to way this is happening.

Along with The.Crazies.1973.iNTERNAL.DVDRiP.x264-tehPARADOX
it has two other files that are extras

The.Cult.Film.Legacy.of.Lynn.Lowry-The.Crazies.1973.iNTERNAL.DVDRiP.x264-tehPARADOX
Theatrical.Trailer.1-The.Crazies.1973.iNTERNAL.DVDRiP.x264-tehPARADOX
Theatrical.Trailer.2-The.Crazies.1973.iNTERNAL.DVDRiP.x264-tehPARADOX

And, I'd love to put the extras on a DVD. I highly doubt it will fit on a single dvd, so my plan was to use a dual layer disc.

Any help would be awsome.

Thanks

VirtualDubMod's MKV support is outdated by several years. Don't expect it to open any MKV file that wasn't made by VirtualDubMod. Use the DirectShowSource AviSynth filter instead (pulldown at the bottom of VirtualDubMod's Open Video File dialog). You can also try using Xvid instead of Divx.

I take it, that this is your response to my post? if so, thanks so much man. I hope it works.

Thank you jagabo for your great insight!
This is a long time after your original post but this error still pops up. I am getting an almost identical crash report to YOUAREtehSCENE. My VirtualDubMod version is 1.5.10.2_b2542.

I am also trying to open an mkv video file and after repeated crashing I tried your suggestion (I wasn't even aware of that feature until you mentioned it) and selected directshowsource per your instruction. The mkv video clip fired right up!

Thank you again!!

You could try using an up to date version of Virtualdub instead of an old version of VirtualdubMod.

How To Open Non-avi Files In Virtualdub

http://forums.virtualdub.org/index.php?act=ST&f=4&t=18798&

Here, a brief explanation is given of how to use the input plugin system to open some file formats that VirtualDub doesn't handle natively.

WMV, M2TS/MTS, MP4 and Matroska (and potentially many other types) via DirectShow

Requirements:

DirectShow input driver (place this in .\VirtualDub\plugins\)
Haali Media Splitter (for MP4, M2TS/MTS and Matroska)
ffdshow-tryouts (for MP4, M2TS/MTS and Matroska)

All you have to do is simply open the file in VirtualDub like you normally would. In case your file doesn't show up, select 'All files (*.*)' from the file type list and after selecting your file, select 'DirectShow input driver' from the file types list.


If you still get error messages then you could post the error log at the Virtualdub forum where Phaeron or StevenV could help you.
