See the simple bash script below. It waits one hour, and makes a 30
min recording.
----------------------
#!/bin/bash
sleep 1h # Instead of using sleep here, you can start the script by using
# the at command, see 'man at'.
cat /dev/video0 > /path/to/some/filename.mpg &
CAT_PID=$!
# $! is PID of last job running in background.
sleep 30m
# You should add some check here to make sure cat is still running,
# otherwise you might accidentally kill some other process.
kill $CAT_PID
