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. :-(
