You shouldn't base this on DEBUG_OSD, this is just for testing the OSD handling
on a text only console.

Just implement your own derived cDevice that implements (amoung all the other things
necessary) the function

cOsdBase *NewOsd()

which returns a cOsdBase derived OSD display class. In that OSD class you
can display the OSD on whatever hardware you desire (see the actual implementation
for DVB cards in dvbosd.c). The basic OSD data is available in the form of a
cBitmap, which should be easy enough to transfer it anywhere where graphics
can be displayed.

You might want to look into the DXR3 plugin for an exampl, since I believe
that plugin must have done it this way.
