It's alredy possible. I did that in my recent experiment on banshee at
it work good. You have to use the vo_osd_changed() to check if the osd
changed or not. Smthg like :

static void draw_osd(void)
{
  if(!vo_osd_changed(0))
    return;
  vo_remove_text(dst_width,dst_height,remove_alpha);
  vo_draw_text(dst_width,dst_height,draw_alpha);
}
