Toff is familiar with Gabest's code in general. Maybe not the subtitle part.
First we should get in touch with Gabest because he's the obvious one to 
fix his bugs and add features. If he doesn't want to (!) or doesn't 
answer, we will consider options, including forking his code or 
restarting from scratch. From that point we'll see who can work on this...

Well, I have nothing against Radlight. It would probably be impossible 
for them/us to work together, but if we give them the specs and the bug 
reports, they would fix it ? Does their filter work in other apps ?
