AFAIK, ffmpeg is (L)GPL, depending on presence or not of certain 

"FFmpeg is free software licensed under the LGPL or GPL depending on 
your choice of configuration options. If you use FFmpeg or its 
constituent libraries, you must adhere to the terms of the license in 
question. You can find basic compliance information and get licensing 
help on our license and legal considerations page." [1]

I don't *think* ffmpeg got deprecated in favour of libav on Debian for 
license issues. The author of the "The FFmpeg/Libav situation" posted by 
the OP seems to suggest the decision was simply based on personal 
preference to Libav by tht maintainer.

As a consequence my ffmpeg (+ jack) screen recording script (and jack 
screen recording in general) is now broken for since months [2] :)

Debian also has 'non-free'...

BTW, if you are pro-GPL you *are* pro-copyright. Just read the GPL 
carefully and you'll see what I mean [3]

Also notice the absence of Debian from the "Free GNU/Linux 
distributions" [4] on the gnu.org website.
