(I broke up long line for other reader's comfort)

I think you are looking for option -endpos.  Quoting from the manual
page:

  -endpos <[[hh:]mm:]ss[.ms]|size[b|kb|mb]> (also see -ss and -sb)
       Stop at given time or byte position.
       NOTE: Byte position may not be accurate, as it can only
       stop at a frame boundary.  When used in conjunction with
       -ss option, -endpos time will shift forward by seconds
       specified with -ss if not a byte position. In addition it
       may not work well or not at all when used with any of the
       -dump options.

     EXAMPLE:
        -endpos 56
             Stop at 56 seconds.
        -endpos 01:10:00
             Stop at 1 hour 10 minutes.
        -ss 10 -endpos 56
             Stop at 1 minute 6 seconds.
        mplayer -endpos 100mb
             Stop playback after reading 100MB of the input file.
        mencoder -endpos 100mb
             Encode only 100 MB.

Hope this helps

That's strange.. Long Wind's original post came across in six lines
for me. It looks like a poem. :)

Interesting. Judging by your headers [1] you are using Google's gmail
web client. Perhaps the Big G is doing the formatting for you?

I suspect the issue is with Long Wind's mailer.

It sent a HTML part which broke the paragraph into several "<div>"s 
(divisions). <div> is a block-level element, so each one is usually rendered 
as a separate paragraph. This is what gives the poem-like forced-structure.

It also sent a text part which, I suspect, was a "translation" of the 
HTML part. This had the same text, but no line breaks at all. In fact, 
where one line finished, the next line started immediately, leading to 
such neologisms as "programi" and "manualit's" (belonging to manualit?).

If your mailer prefers HTML parts, you probably saw six lines. If it 
prefers text parts, you probably saw one (perhaps wrapped).

i knew -endpos, it's not option i seek
(maybe my english isn't good enougheven i wrote so many words, i'm still misunderstood)
arecord has such option: -d 
it will record for specified time and exit
mencoder doesn't seem to have such -d

That is right. But with -endpos you can do what you want.

If you start at the beginning, endpos is the same as duration.

If you start at a later point, say t, endpos = duration + t

So I hope you can achieve your aim anyway.

Thank Tomas! You are right!i test it, it's option i need
(i thought they are two tasks, one for live recording, the other for clip extraction from a existing video fileso there should be two options
it turns out -endpos is for both task)
