Re: Simple Filter leading to a CODEC

If you want to do this using our library, then you would write your 
own 'filter' class - i.e., a subclass of "FramedFilter" - for 
encoding each frame.  In particular, your "FramedFilter" subclass 
would implement the virtual function "doGetNextFrame()".

I suggest that you start by taking a look at our implementation of 
the "uLawFromPCMAudioSource" class, because that's the closest thing 
that we have in our library to a 'codec'.
