[MPlayer-users] Cutting up .AVI's

[Sander Smeenk]

Quoting Arpi (arpi at thot.banki.hu):

> huh?

Jup, my mistake. So I tried -sb with a byte-value:

$ mencoder -ovc copy -ovc copy -oac copy -sb 737256868 -o part2 file.avi

And now mencoder complains that it doesn't know what type of file this
is:

| $  mencoder -ovc copy -oac copy -endpos 706mb -o part1.avi file.avi

This works, for the first part.
Then the second part:


| $ mencoder -ovc copy -ovc copy -oac copy -sb 740639072 -o part2.avi file.avi

:(
I tried specifying -vc but it keeps failing like this...
