Vdubmod crashes, why ?

[Alain_French]

Hy,

I make capture with hauppauge nexus in mpeg2 or pva (and pva2mpg after) and i have some problems...
Vdubmod crahes often at the end of the encoding, and i don't know why, i put the rapport here if you can tell me what is the problem...

- i tested 2 versions of vdubmod, and i have the problem with the last one.
Perhaps this is a problem with :
- pva or mpeg2 make by the capture program (hispadvb)
- xvid problem
- windows problem
- ???

Perhaps is it clear for you but not for me.

[Suiryc]

Sounds more like a crash in the deinitialization code of mpeg2dec3 (all the last function calls are inside AviSynth and this mpeg2dec3 plugin).

[sillKotscha]

try to demux/fix your mpeg2/pva with pvastrumento... it generates 2 files: *.mpv and *. mpa

this fixed (if mpeg2 stream has had a wrong GOP structure) mpv stream can now be decoded properly by dvd2avi...

so, use something like this:

1)

videosource= blabla/*.d2v
audiosource= blabla/*.mpa
return audio_videodub (this line isn't exact - I know, I can't really remember but search and you will find the right one for it :P)

here you have to load mpeg2dec3(dg) and mpasource as plugins

or 2)

videosource= blabla/*.mpv
audiosource= blabla/*.mpa
return audio_videodub

here you have to load MPEGdecoder and mpasource as plugins

if you load this script directly in VDub it will generate a d2v file by itself...

now you can see if fixed mpeg2/pva stream still crashes Vdub

Hello,

I also encountered this issue. After reading this thread, http://forum.doom9.org/showthread.php?s=&threadid=61625&highlight=virtualdubmod+crash+close, I reverted to VDubMod 1.5.1.1a. So far, so good.
