command line tool to automatically cut avi file in HALF

[Choller]

I've been searching for ages for something to cut an .AVI file in half. Based on either the keyframe or the filesize/length whatever.
Only thing mandatory is that it has to be able to run from commandline. I couldn't figure it out using nandub/vdubmod. I can only split it with them if I know the total keyframes. But I want to split it automatically.

Anyone know of any tool that will do this?

I would try ffmpeg or avidemux. Just google for cutting examples.

ffmpeg has a good one but unfortunately it doesn't cut avi's. avidemux seems to have an option too but it didn't work for me. I made a thread about that here and in avidemux's own forum.

Any other suggestions are welcome. No luck so far
