Access Violation in VirutalDub

Post by Watatashi » Sat Dec 06, 2014 3:08 pm

I recently ripped some Blu-ray footage of RWBY using MakeMKV. In order to edit using this footage I need to convert it from .mkv to .avi. I have created the following Avisynth script to load it into VirtualDub to save this footage as .avi.

Code: Select all

FFVideoSource("RWBY Trailers.mkv")
I am able to open the file in VitualDub but when I try to play or scrub through the footage I get the following error message

Avisynth read error:
CAVIStreamSynth: System exception - Access Violation at 0x10012380,
reading from 0x740

What does this mean and what do I have to do for this to work?

Has anyone else had this problem in the past? Anyone have any idea of how this problem can fixed?

BD avc streams are a bit troublesome, generally speaking it's best to handle them either through DGAVCDecNV (though it's not free), or LSMASH Works (free solution).

For LSMASH Works, you'll need the proper avisynth plugin (it's included in the AMVPack) and then use:

Code: Select all

LWLibavVideoSource("RWBY Trailers.mkv")
To load footage.

Okay thanks. I'll give that a try and let you know how it works.

Actually, I just did some quick searching for a way to download either of those programs but I can't seem to find anywhere? Can you supply me with a link for both? Or Let me know where to look?

That particular error is a memory error, you can get those browsing around scripts in VirtualDub and may not have an issue when saving from the same script. That said, mirkosp is right, LSMASHWorks (or DGAVCDecNV if you buy it and have a supported Nvidia card) is the best solution as FFMpegSource does not properly decode Blu-ray footage.

So where can I get LSMASHWorks? And what is it exactly? Is it a program? Plugin?

And what is DGAVCDecNV? Does it still use scripts?

I also wanna know if my 1023MB NVIDIA GeForce GTX 750 (EVGA) Graphics card is compatible?

Sorry for all the questions. I've never ripped from Blu-ray before and am running into quite a few problems and am just looking for the easiest way to prep this footage for editing.

As I said, LSMASHWorks is included in the AMVPack, which I did link above.

As for DGAVCDecNV, you can find more info here. Your GPU is compatible with it, yes.

Okay. Thanks so much guys. I'll just do a fresh install of the AMVPack and see if this fixes the problem. I've been using the AMVApp for some time and I should probably update anyway.

Yeah that cleared things up pretty great! Footage was interlaced but I fixed that as well and the footage came out looking great!!! Thanks so much again guys.
