AviSource + AutoCrop + avs2yuv crashes

[vlada]

Hi,

if I open a video using AviSource, then apply AutoCrop filter and want to process it using avs2yuv, then avs2yuv crashes.

If I replace AviSource with FFmpegSource, then everything works. Also there are no problems if I remove the AutoCrop filter.

Could someone please confirm this? Do you have ideas where the problem lies?

The VFW codec for your file is broken.

Or your file is corrupt and the VFW codec crashes but FFmpeg codec rides over (but may have planted a bomb) the problem.

Yes, it was probably a bad codec, because on another computer I have no problems. What confused me was, that the .avs script worked flawlesly with VirtualDub, but caused avs2yuv crash.

...worked flawlesly with VirtualDub...No, it probably just didn't spit anywhere that you noticed. :p

I did some more testing and I found out that the "bug" (yes I do believe there is a bug somewhere) is very rare. But I managed to reproduce it on 3 different computers. There is a 4th condition to reproduce it - XviD must be the codec which decodes the AVI. If I replace it with ffdshow VfW, then the crash doesn't happen.

So the problem is either in avs2yuv, avisource, autocrop or xvid. Unfortunately avs2yuv+avisource+autocrop is the combination I want to use and since I'm building a program that should work on any computer, I need to make it work even if the people will have XviD installed.

I could use FFmpegSource as default (which is my current workaround), but FFmpegSource indexes AVI files before opening, which takes quite a long time.

Autocrop is probably just triggering the crash because it does a quick scan through some frames upon loading. If you remove autocrop, is it possible to process the clip completely from beginning to end?
