Video grab using ffmpeg?

Does anyone know how to grab video (screen) on Terminal using ffmpeg (not X11).

I have written a unix library and I'd like to make a short movie (demo) of it.

Tried: I already own SNapz Pro2 but it hangs the system (I have an old Powerbook 15" PPC). I guess my system is too slow for version 2.

I have tried some sharewares too, am in no mood of buying new stuff if i can use ffmpeg. ScreenFlick is good but puts a watermark. The resultant file for a full screen 2 minute or so movie is only 1-2 MB which is great.

Screen Movie Recorder also made a good demo movie (mov format) but its a 4 GB file.

The ffmpeg howto gives commands for video grab on X11, btw.

XtUngrabKeyboard()														XtUngrabKeyboard()

Name
  XtUngrabKeyboard - release an active keyboard grab.

Synopsis
  void XtUngrabKeyboard(widget, time)
	   Widget widget;
	   Time time;

Inputs
  widget    Specifies the widget which has the active keyboard grab.

  time	    Specifies the time when the grab should end.  CurrentTime is acceptable.

Availability
  Release 4 and later.

Description
  XtUngrabKeyboard() releases an active keyboard grab by calling XUngrabKeyboard(), passing the display of widget and time.

  The  time  argument  may  be a timestamp or the constant CurrentTime.  If the specified time is earlier than the last-keyboard-grab time or
  later than the current server time the keyboard will not be ungrabbed.

  See XtGrabKeyboard() for more information about grabbing the keyboard.

Usage
  Most applications will never need to issue a grab.  XtAddGrab() (called by XtPopup()) can be used  to  implement  modal  popups  inside  an
  application,	and  XtSetKeyboardFocus()  can	be used to redirect keyboard focus within an application.  Neither function actually issues a
  grab, and so does not interrupt event processing by other clients.

  XtUngrabPointer(1).
