Fraunhofer FDK license

I'd add it, it is a gpl incompatible opensource license.

No problem to add it. But IMHO the usage restriction in section 3
makes it non-free:

"You may use this FDK AAC Codec software or modifications thereto only
for purposes that are authorized by appropriate patent licenses."

Indeed, and this opens another can of worms since (as far as I can see) there
are no specific license clauses in the AAC patent license for applications
that may be distributed without cost. I.e., licensing fees still apply as "per
unit fee".

Sometimes I have the feeling that Fraunhofer (which is after all funded 30% by
German federal and state money) just "does not get it".

I believe that I can go to BINARY-REDISTRIBUTABLE. But please check if
the following rules apply here:

# - MAY require explicit inclusion of the license with
# the distribution [1]
# - IFF there is an explicit inclusion requirement, USE=bindist
# MUST cause a copy of the license to be installed in a file
# location compliant with the license,
