Avisynth ( access violation error )

[mishu76]

Hi there,

I've been searching the forum for about 30minutes now but couldn't find an answer to my question.

I´ve tried to encode my Gladiator.avi to svcd with CCE and dvd2svcd!
But when i open my .mpg, the mediaplayer shows me a black screen with the message:

Avisynth: cought an access violation at 0x0f66c965, attempting to read from 0x0bdc4000

How can i solve this problem? I also get this error with other DivX´s!
Or should i delet this avi´s? :(

thanks a lot :)

Hi mishu76,

please post your "AviSynth_Script_file.avs" file - open it with notepad and paste it here.

Hope this helps :)

LoadPlugin("C:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec.dll")
AVISource("H:\Filme\GLADIA~1\GLADIA~2.AVI")
ConvertToYUY2()
BicubicResize(480,540,0.00,0.60)
AddBorders(0,18,0,18)

Hi again,

hmm, all in all, the script looks ok to me. But dealing with downloaded DivX/AVI surces it's sometimes tricky for the whole conversion process because of the possibility of bad frames within the source.

So you can try to do the following:

1) Try to use the MPEG2DEC2.DLL by Tom Barry, he has doubled the buffers in it and made it more stable besides some P4 SSE/2 optimizations. Just go to "Frameserver" tab, hit the little button with the 3 points on it in the "MPEG2Dec" row of the table and then choose the MPEG2DEC2.DLL instead of the MPEG2DEC.DLL.

2) If this doesn't work, then try a different resize method sometimes SimpleResize does a better job and sometimes Bicubic or Billinear.

3) If using the Bicubic or the BillinerResize, you could try to use the "ConvertToRGB()" command instead of the "ConvertToYUY2()" in the Avisynth script by ticking the "Edit as part of Video encoding" option in "Frameserver" tab. When the script window pops up, just change the line and hit "OK".

4) According to this thread you can try to check/fix the DivX/AVI if it contains some bad frames that bomb Avisynth afterwards.

See here (saber's suggestion and the link dvd2svcd gives on page 2):

I know, it's a lot of stuff to try but if you want to keep those files it's perhaps worth the time.

Hope that helps,
Gerti

Juppi,

I can´t wait and so I tried it over night! --> and yes it works!

I used the MPEG2DEC2.dll and SimpleResize !!!!!

So I hope my other AVI/DivX will also work with this method!

Gerti67 -> You are the Master :)

Thanks Mishu76
