IANAL, but at least the opencore/NOTICE file says this:

Portions of this file are derived from the following 3GPP standard:
    3GPP TS 26.073
    ANSI-C code for the Adaptive Multi-Rate (AMR) speech codec
    Available from http://www.3gpp.org
(C) 2004, 3GPP Organizational Partners (ARIB, ATIS, CCSA, ETSI, TTA, TTC)
Permission to distribute, modify and use this file under the standard 
terms listed above has been obtained from the copyright holder.

(And a similar one for AMR-WB.)

So as far as I can tell, PacketVideo has the right to license these files 
under the apache license.
