I'd like to have a better understanding

fdk:

Redistribution and use in source and binary forms, with or without
modification, are permitted without
payment of copyright license fees provided that you satisfy the
following conditions:

(A)
You must retain the complete text of this software license in
redistributions of the FDK AAC Codec or
your modifications thereto in source code form.

(B)
You must retain the complete text of this software license in the
documentation and/or other materials
provided with redistributions of the FDK AAC Codec or your modifications
thereto in binary form.
You must make available free of charge copies of the complete source
code of the FDK AAC Codec and your
modifications thereto to recipients of copies in binary form.

(C)
The name of Fraunhofer may not be used to endorse or promote products
derived from this library without
prior written permission.

(D)
You may not charge copyright license fees for anyone to use, copy or
distribute the FDK AAC Codec
software or your modifications thereto.

(E)
Your modified versions of the FDK AAC Codec must carry prominent notices
stating that you changed the software
and the date of any change. For modified versions of the FDK AAC Codec,
the term
"Fraunhofer FDK AAC Codec Library for Android" must be replaced by the term
"Third-Party Modified Version of the Fraunhofer FDK AAC Codec Library
for Android."

Currently the mismatch is (E) more than (D) in my eyes.

D is a match for lgpl-2.1 2. c

    c) You must cause the whole of the work to be licensed at no
    charge to all third parties under the terms of this License.

The second part of E is a stronger version of the non-endorsement clause
from bsd (that is compatible) so I'm not sure it could be considered an
additional restriction.


Could we have a specific detail on which section clashes?
