opus - Mar 2010 - A bi-drectional audio question

Hi all,

We have added celt to our application.
We can get celt to encode/decode audio in one direction.
It can be in either direction but, not both directions at the same time.
Here is the problem from my programmer:

The celt codecuses global static data and this makes it impossible to make two
instances.

This prevents us from making VoIP applications that need to code and decode at
the

same time.



Any suggestions/ideas?

Thanks so much in advance.

Sam Bushman

Do not use the pseudo-stack, use alloca or c99 var-arrays. These are
configuration options. Any platform with threads should have one or
both of these facilities.  Then the only 'shared' data will be
read-only.
