[opus] opus library issues

[Leonid Shigris]

Hi Greg,

Attached my opus config.

As you suggested not to use VLA, what changes are required in configurations?



Pls advise,

Kind Regards,

Many people have run opus on small embedded devices.  It may be the case that your VLA support isn't providing enough stack.  You may want to try using the pseudostack mode which will instead put that memory on the heap and give you better control over making sure you have enough available.
