The OSD is done more or less in hardware. At least on the hardware level
it must be a framebuffer seperate to the one beeing used by the MPEG

Yes for example ncurses. When we have a limited set of VT100 commands we
could run ncurses. But we could go a bit beyond. For about commands for
drawing lines, and circles and stuff. Maybe even bitmaps.
