send the design draft to the list, i'm sure many of us is interested.
if you have tech questions, implementation problems with libmpcodecs,
feel free to ask me. i really want to see audio filters in libmpcodecs
instead of libao2. we should also solve audio format and others
(like support for volume mixer) query from libao2 drivers, it is
required for auto-loading plugins.

i can imagine something like vf.h interface for audio, converted from
libao2 interface, and having a wrapper af_ao between them at the end
of the filter chain.

about the osd equalizer - should not be too hard to implement, with new
sub API, as soon as i have some time, i'll try to put something together.

btw, if you accept that patch for disabling format-incompatible plugins
runtime, it should be commited for the soon-coming 0.90.
