DirectShowSource troubleshooting

[talfarlow]

Hi!

I'm feeding an MJPEG clip into VirtualDub using DirectShowSource in my AVISynth script. After the initial processing seconds at opening time, VirtualDub closes with no error message at all: it just vanishes and I have no chance to see the clip loaded. Otherwise, the clip is correctly opened in VirtualDub manually, and also properly played in Media Player Classic.

As a simple example:

#ASYNTHER Test
a = DirectShowSource("t:\DSCF0001.AVI")
return (a)

This triggers the crash, no further processing is needed to get it. What's happening?

:thanks:

What is your OS and what is the version of Avisynth?

A DirectShowSource log file might give a hint :-#ASYNTHER Test
a = DirectShowSource("t:\DSCF0001.AVI", LogFile="t:\MyDSSLog.txt", LogMask=-1)
return (a)
