[FFmpeg-devel] [RFC v4] libbavcodec: add a native decoder for the Daala video codec

[Rostislav Pehlivanov]

I'm not sure about that, the page doesn't list what happens if an LGPL
project uses some parts of a BSD project. The decoder was started from
scratch and the parts which were taken from libdaala (DCTs, PVQ and the
entropy decoder) have had major modifications done to them. So I still
think it's fine to just state the Xiph copyright and use only the LGPL
license.

I found this page which states that I'm allowed to do this:
http://lucumr.pocoo.org/2009/2/12/are-you-sure-you-want-to-use-gpl/

And it does make sense, the license says to always keep the copyright but
does not say to retain the BSD license nor what would happen should major
modifications be done to it. Hence why it's GPL compatible.
