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.

tixutils
Utils(n) Tix Built-In Commands Utils(n)
__________________________________________________________________________________________________________________________________________________
NAME
tixUtils - Utility commands in Tix.
SYNOPSIS
tixDescendants pathName
tixDisableAll pathName
tixEnableAll pathName
tixPushGrab ?-global? window
tixPopGrab
_________________________________________________________________
DESCRIPTION
tixDescendants pathName
Returns a list of all the descendant widgets of pathName plus pathName itself.
tixDisableAll pathName
Disables pathName and all its descendants.
tixEnableAll pathName
Enables pathName and all its descendants.
tixPushGrab ?-global? window
The tixPushGrab and tixPopGrab commands allows you to perform "cascade-grabbing". tixPushGrab calls the grab(n) command on window
and saves window on a grabbing stack.
tixPopGrab
tixPopGrab pops the top-most element from the grabbing stack and release its grab. If the grabbing stack is not empty, then tixPop-
Grab will execute grab(n) on the current top-most element in the grabbing stack.
NOTES
Some Tix widgets (for example, tixComboBox and tixPanedWindow) grabs the screen on certain occasions using tixPushGrab and tixPopGrab.
Therefore, if you need to grab the screen when these widgets are present, you should also call tixPushGrab and tixPopGrab in place of the
Tk grab and grab release commands. Otherwise, the behavior of these widgets may be undefined.
