Hey folks,  I fear I have sad news for the faac package. Besides 
that the debian/copyright file is wrong anyways (it claims GPL 
license, which is wrong), it came to my attention that the package 
itself is probably non redistributible. Please see 
https://launchpad.net/bugs/374900 for the
sad details.

In short, the following 3 files are affected: - 
libfaac/bitstream.c - libfaac/tns.c - libfaac/tns.h 
 
All these files carry this Copyright notice: 
 
This software module was originally developed by 
and edited by Texas Instruments in the course of 
development of the MPEG-2 NBC/MPEG-4 Audio standard 
ISO/IEC 13818-7, 14496-1,2 and 3. This software module is an 
implementation of a part of one or more MPEG-2 NBC/MPEG-4 Audio tools 
as specified by the MPEG-2 NBC/MPEG-4 Audio standard. ISO/IEC gives 
users of the MPEG-2 NBC/MPEG-4 Audio standards free license to this 
software module or modifications thereof for use in hardware or 
software products claiming conformance to the MPEG-2 NBC/ MPEG-4 Audio 
standards. Those intending to use this software module in hardware or 
software products are advised that this use may infringe existing 
patents. The original developer of this software module and his/her 
company, the subsequent editors and their companies, and ISO/IEC have 
no liability for use of this software module or modifications thereof 
in an implementation. Copyright is not released for non MPEG-2 
NBC/MPEG-4 Audio conforming products. The original developer retains 
full right to use the code for his/her own purpose, assign or donate 
the code to a third party and to inhibit third party from using the 
code for non MPEG-2 NBC/MPEG-4 Audio conforming products. This 
copyright notice must be included in all copies or derivative works. 
 
Copyright (c) 1997. 


According to ffmpeg upstream (and I tend to share this opinion), 
this
makes it impossible to redistribute it in a package that does not 
claim
to be MPEG-2/MPEG-4 conformant, which in the end is against the 
spirit
and letter of the (L)GPL.

At this point, I fear we'll have to pull out this package. :-(
