Well, not yet completely. There is still graph parsing and ffmpeg.c 
integration missing...

No, there is not yet such a filter, but it is in the wishlist: 
http://wiki.multimedia.cx/index.php?title=Libavfilter#Feature_wish_list 
. Actually, it shouldn't be too hard to add subtitles filtering support 
to avfilter. For the hardsub filter implementation, there is quite a bit 
of code that can be copied from ffplay.c.

I'm wondering if this would be a nice qualification task for 2008 SoC 
(unless, of course, if you want to give it a try before).
