(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

i knew -endpos, it's not option i seek

(maybe my english isn't good enough
even 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

Thanks anyway!
