True. I just didn't feel the need for my script as I alway have the same kind of \
input, but for a general script, lavinfo would be the best thing.

I'm attaching the script. Maybe Enrico can find something useful in it. It assumes it \
knows very much that probably is not true anywhere but in my home.

It assumes, among other things:
That all files but the last is 10000 frames long.
That all files has a - in the name.
That you want a clip list that can be played in the same directory the files are \
located in.

It outputs an edit list on stdout. My typical use is:

python vw.py path/to/directory/ >clip.list

It is, though, an example of how to let a script create an edit list.
