Hi!
How is it possible to code/decode MPEG formats on hardware with core audio ?
We have already written a core audio driver for linear soundcards
with IOAudioFamily,
but we would like to support hardware coding/decoding MPEG1 MPEG2
(and eventually MP3)
with our sound cards.
Perhaps it'd be good to use the CFPlugin framework for
hardware-accelerated stuff?
I predict AudioUnits will be a festive arena for plugin developers,
and there's no reason that plugins shouldn't have the capability to
do hardware acceleration directly...
So I would recomment just making your hardware AudioUnits-friendly,
and then building an MP3 Codec using AudioUnits that plays nicely
with all the other AU's in the system.
(Sorry if this has already been discussed - I'm catching up on email
that interests me ...)
