If you compile DirectFB with the multi-application core, you can have one app draw the video window and another app draw a (translucent) window on top of it. You may create the window with true alpha channel and/or apply a configurable window opacity. The multi-application core is still considered experimental but it seems to work pretty well nevertheless.
