Basic AVI command-line editing

[Andrew P.]

Hello!

I have a headless file server with hundreds of avi-files. I was
wondering if there's a means of some basic command-line editing - like
concatenation and stream processing. I checked with the ports
collection - but there's no such tool. Does anyone know a suitable
program? Maybe just some script?

I'm already reading MS AVI and OpenDML docs, as I feel that I'll have
to write it myself...

Thanks,
Andrew P.
