excellent! will it work with the existing subtitle system, i.e. stuff
like ssa/ass subs embedded in mkv?

agree. but i think you should instead make a vf control() call to send
the current timestamp down the vf chain, instead of using globals.
other filters will ignore it, but vf_asa can grab it and know what
subs to display next.

yes but it's impossible to get good performance without the osd calls
integrated into the vo rather than in a separate filter... :(
