video device dimension

    Dec 14 2011 | 5:39 pm
    Sorry I've allready posted that question but got no answer so I try again (I realy bang my head againts that).
    I wonder how I can get the exact dimensions (or, maybe, the ratio) of a video device (a camera...) with jit.qt.grab. Quick time can do it when recording but I can't see any message or attribute (like @adapt, for I could send to jit.qt.grab that allow automaticaly grab the video device dimensions.
    any help greatly appreciated
