VirtualDub / AviSynth error

beau kang · Post by **beau kang** » Sun Aug 06, 2006 2:38 am

I recently had to reformat my laptop and lost all of my codecs and everything needed to make an AMV. I tried to reload everything that I could and have VirtualDub, AviSynth, and a few other codecs and stuff installed, but I've been getting an error. It tells me:

Avysynth read error: CAVIStreamSynth: System exception - Access Violation

It usually happens as I'm scrolling through my vid to check the quality and I end up getting stuck on a frame. I don't know if these are later additions of the programs that I downloaded or what, but whatever questions or suggestions I can get would be helpful.

Thank you.

What format is the video in?

The videos are regular .vob format. I got them from a copied version of the original dvd's from my friend. He said that he used DVDShrink to make the copy, and it plays just find whenever I use it in the DVD player or on my computer.

I use DVD2AVI to make the .d2v file and open that up with my .avs script in VirtualDub. After I move the slider bar around some, I get the error.

Sounds like avisynth/vdub is trying to use more memory than is normally allotted to the process.
try using the setMemoryMax(int) function, and see if that helps
first try 16, then 32

another way you may be able to avoid this is to hold ctrl down while sliding (slide by keyframes)

I'm having the exact same problem. I tried the above with no luck.

Sorry for the double post but my deadline is in 9 days and I desperatly need help. I'll try and describe my situation as best as I can.
Ok so when I open my AVS script in virtualDub it's pretty much the same as beau kang's problem. When I'm scrolling through the footage it freezes on a frame and I get 'Avysynth read error: CAVIStreamSynth: System exception - Access Violation' or sometimes I don't see anything at all. Just a black screen. This is my code:

Code: Select all

LoadPlugin("F:\AviSynth 2.5\plugins\MPEG2Dec3.dll")
LoadPlugin("F:\AviSynth 2.5\plugins\Decomb.dll")
MPEG2Source("F:\FMA RIP\d2v\Fullmetal.d2v")
AssumeBFF()
Telecide(guide=2, post=4)
Decimate(quality=3)

When I remove the last 3 lines it works. Any help would be greatly apreciated. Thanks in advance ^^.
