No.  The BSD-style license does not affect your own code.  It only
requires attribution of the use of the Xiph code by including the
original license text somewhere.

The Xiph copyright/license attribution will need to be preserved, yes.
That's not the same as releasing your own product under a BSD license.

You're not liable for enforcement.  You need only follow the terms of
the license yourself.
