mencoder-g2 ?

i was wondering, is anybody working on an mencoder port to g2, or is
there still some major work that needs done on g2 before it wold be
feasible?  if it's just that nobody has worked on it yet, i might give
it a shot.

also, as i understand it, one advantage of g2 over g1 is that it can
process multiple streams at once, and this would be great to put into
an mencoder-g2 eg. for ripping multiple dvd audio tracks, etc.  i'm
just not sure how it would work with mplayer's command-line processing,
especially what sort of syntax would be used to specify possibly
different encoders/encoding options/filters for different streams.  even
with g1, just specifying a decent set of encoding options for one stream
gets a bit unweildy.  as much as i hate the abundant over-use of guis
when there's no need, a gui for selecting tracks to encode, along with
filters and encoding options could be much nicer than the command line
for more complex encodes.

or does somebody have an idea for a good command-line syntax?
