MeGUI Error / Evaluate: System exception - Access Violation

[thedozer]

Hi

I have some AVI files encoded in H264 and using AVISource in AviSynth the script file plays fine in MPC and in VirtualDub but when I try to Enqueue the script file in MeGUI I get this error message:

The file C:\Encode\Video.avs cannot be opend.
Error message for your reference: Evaluate: System exception - Access Violation
(C:\Encode\Video.avs, line 1)

The script file is very normal:

AVISource("C:\Encode\Video.avi", audio=false)
Lanczos4Resize(512,288) # Lanczos4 (Sharp)


This problem occurs only in Vista but not in other XP machines that I tried.

I'm using x264 VFW to decode because ffdshow adds some green frames that I couldn’t get rid of.
Also I'm using the latest versions of MeGUI (Updated) and AviSynth

Any ideas how to fix this error?


Thanks in advance

Sorry I can't help but let it be known that I'm having the same problem with the latest MeGUI and Vista.

I think maybe the problem is originated from Vista's .Net Framework files but that's a guess since I don't have any debugging experience.

the error goes away when using ffdshow to decode x264 but the problem is those green frames that I tried to fix for months without any luck.

Are you Vista guys running as administrator?

[thedozer]

yeah i'm running in administrator and with UAC turned off

Of course.

EDIT: Screw this. I don't know why I installed Vista. I'm going back to XP to solve the NUMEROUS issues I'm having.

There are something missing in your decoding filters chain...ensure you that you have the appropriate filters.

it doesn't concern megui, nor Vista itself I believe. :)

[saint-francis]

I'm not sure. This problem began for me as soon as I installed the recent update. Several hours before all was fine.

[Sharktooth]

nothing changed in recent updates in regards of DS or AVS...

[thedozer]

its a possibility that the problem is coming from using these two together [x264 VFW & MeGUI] cuz when I use ffdshow for decoding with MeGUI the problem is gone.

and the most important part is that this problem is only in Vista not in XP although they have the same apps and codecs installed.

i dont think x264 VFW is involved since it is an ENCODER and not a DECODER.
something is wrong in your directshow chain/filters.

[Kurtnoise]

There is a decoder now, within the last builds (http://sourceforge.net/projects/x264vfw/)...

[Sharktooth]

then... the advice is to read the x264 sticky ;)
x264 VFW (no longer officially supported - mantained by third party developers)...
...
(at your own risk)

maybe ask them to fix.

well I'm using it as a decoder because ffdshow adds some green frames to the video that I have been trying to get rid of for months now but without any luck.

after struggling with this error problem I have found two solutions:
1. use DirectShowSource with AVI files.
2. ditch Vista and revert back to XP

I think I'm going with solution number one because I'm feeling a little lazy now.


thanks for everyone, really.

[Sharktooth]

x264 is an ENCODER, you cant use it as a decoder.
x264vfw is a package containing x264 (video for windows encoder) and ffh264 decoder.

[thedozer]

yeah but what can I do I had no choice
anyway, since x264 is no longer supported I will stick with useing DirectShowSource with AVI files for now until maybe in the future it will be fixed

BTW & off topic, all emails coming from this forum into my hotmail inbox are treated as highly dangerous content!
maybe there is a problem here that needs to be fixed!

x264VFW is no longer supported. x264 is active ;)
install FFDShow. it has a h.264 decoder that works for both VFW (you have to manually enable it in the options) and DS.
concerning emails, your spam filter smoked something bad... ;)

[thedozer]

well thanks Sharktooth sorry for the time waste

[Sharktooth]

np, hope it will work.
