*
* Status:
* - plays .avi streams, video only
2003-08-18 22:11:29 +02:00
* - requires Microsoft avifil32.dll and builtin msvfw32.dll.
*
* Todo:
* - audio support (including synchronization etc)
* - replace DirectDraw by a 'normal' window, including dithering, controls
* etc.
2002-06-01 01:06:46 +02:00
*
* Bugs:
2002-06-01 01:06:46 +02:00
* - no time scheduling, video plays too fast using DirectDraw/XF86DGA
* - requires DirectDraw with all disadvantages.
