Extracting some specific frames from mpeg4 video using ffmpeg

[Redhat_doom]

Hi All,

I have a huge mpeg4 video and I want to extract only 200MB of the video starting at time 1000sec. How can I do so using ffmpeg? Thanks a lot!

if
`-ss position'
Seek to given time position in seconds. hh:mm:ss[.xxx] syntax is also supported.

doesn't work (to jump to the position), it probably can't be done with ffmpeg.
