The callback function is set with :ref:`OBJSetCallbackFunction`, for example
``OBJSetCallbackFunction(hVideo, "VideoPos", "VideoPosCallback")``

If the position is changed, the following callback function will be invoked::

   def VideoPosCallback(hVideo, pos)
   {
   }

If the mode is changed (start, stop, pause), the following callback function
is invoked::

   def VideoModeCallback(hVideo, mode)
   {
   }

*mode* is one of the following values::

   #define MCI_MODE_NOT_READY  524
   #define MCI_MODE_STOP       525
   #define MCI_MODE_PLAY       526
