opening file used by other thread

Can it be done? I can open file used by other app witch Virtualdub with "pop up extended options" and "open in avi compatybility mode" but avisynth can't. Are there such extended options in OpenDmlSource?

I can open a AVI as often as I want for read access. What exactly do you want to do?

A shot at it could be to use the VirtualDub frameserver - frameserving the frames to AviSynth.

I wanted to open and preview partially downloaded avi file while downloading without copying it. I could preview it in VDub but I wanted do it in any player. VideoLan player can open that file too, but it's crashing after a little seeking. I read that function OpenDmlSource() is taken from VDub and thought that it will be working similarly.:confused:

AFAIK a partially AVI has no valid index, so only (few) progs which rebuild that index (as VD) can open it.
