Cutting bad frames with VirtualDubMod

[lazaruz]

I know how to fix broken avi-files with VirtualDubMod but I'm looking for a way to do it from the commandline.

I'm not sure as to do this, do I need to create some sort of script, if so how?

I dont't need anything advanced, just to:

* Load the video
* Scan for errors
* Delete or mask bad frames

DivFix++ has a command line syntax. http://sourceforge.net/projects/divfixpp

Ok, so I've been playing around with DivFix++ and it seemes to fix it to some degree.
When I scan the fixed file in VirtualDubMod it seemes fine but I still have a problem.

The thing is that the file has a packed bitstream and I'm trying to unpack it with MPEG4 Modifier
and it couldn't open the original file, I got:

"This is not a valid MPEG-4 Video (Startcode not found at begining of frame)"

After the fix from DivXFix++, I now get:

''Too many VOPs in a frame.''

Acording to another forum:

"you will get this if there are more than 2 VOPs in a AVI frame. Usually there is only one, or 2 for each packed frame when packed bitstream was used."

The file created with DivXFix++ has 3 VOPs, could this be an error in DivXFix or can there be more than 2?

When I disable that error-check in MPEG Modifier the file unpack and plays just fine so I got to wonder in which application the error lies.
