without looking at the code:
close() is the public (as used by pix_video) function (as defined in
video.cpp), that in turn calls stopTransfer() (if needed) and
closeDevice() (if needed)
at least, it _should_ do that.
if it does not, then there is a bug somewhere...

there is a bug in Pd that does not call the object's
destructors/closefunctions when quitting Pd.
i once tried a fix but it was not accepted (i think thomas grill spotted
some problems with my fix)
