   2  * Very simple AVIPLAYER
   3  *
   4  * Copyright 1999 Marcus Meissner
   5  *
   6  * Status:
   7  *      - plays .avi streams, video only
   8  *      - requires MicroSoft avifil32.dll and builtin msvfw32.dll.
   9  *
  10  * Todo:
  11  *      - audio support (including synchronization etc)
  12  *      - replace DirectDraw by a 'normal' window, including dithering, controls
  13  *        etc.
  14  *
  15  * Bugs:
  16  *      - no time scheduling, video plays too fast using DirectDraw/XF86DGA
  17  *      - requires DirectDraw with all disadvantages.
