If I understand you correctly, from the subpicture point of view, it
would need to have a handle on the video output driver (video_out),
and then each time it wants to display a new subtitle it would do a
vo2_display_overlay(video_out,image,duration).  Is that it?  In which
case this could be quite easy.  Do you already have an API to display
overlays?  Can the Matrox G200 or NVidia Riva TNT do this overlay
thingy (that's what I can test with)?
