That's a good point.  I just checked, and it seems that there is quite
a bit of code which references ACM data structures in loader/acm.c and
loader/wine/msacm.h.

So for those of you just joining the party (the Open H.323 list and
the MPlayer lists), we're trying to get access to the Microsoft
G.723.1 codec distributed with Windows from Linux so we can make cheap
telephone calls around the world without using a lot of bandwidth.
This enables, among other things, the ability for Gnomemeeting to talk
to a Quicknet card using the optimal G.723.1 codec.

I have a few questions:

 - Does the ACM code in mplayer depend on any mplayer-specific stuff
   that would have to be provided in order to load and use ACM codecs?

 - For the Open H.323 guys, is it feasible to extend the video codec
   layer to access all the codecs provided by mplayer's video codec
   interface?  Last time I poked around in there, I saw all sorts of
   hard-coded references to H.263 and friends.

 - Is anyone aware of any codecs comprable to G.723.1 with better
   audio quality and/or less bandwidth usage?

Apologies for the massive crosspost.
