Two easy things come to mind: a borderless window (similar to my
'nixieclock' app) placed over the top of your video playback window
so that it can draw whatever it wants; double buffering for smooth
scrolling, anti-aliased fonts, etc. eg:

..where I just placed the nixieclock borderless window
over a video playback.
But that won't really let you have letters "superimposed"
over the video. The letters would have to be on a rectangle,
similar to closed-captioning. There might be native OS calls
you can use to make the FLTK windows 'see through'; I have
no details on that though.
The other way would be drawing into the overlay planes,
like the way a screen-capture app lets one drag out a
rubber band selection over the entire screen.
But I don't know if FLTK supports rendering text into the
overlay plane.. might only support shapes and vectors in
very limited colors, not sure.
