Comment # 24 on bug 2736 from Nicolas Chauvet

@Eric, same for you if you want to co-maintain.
Feel free to assign the review, I should have fixed your earlier comments, thx.

About your last comment, fdk-aac is GPL incompatible (according to ffmpeg folk
because of some additional restrictions added to the files headers to the
LGPL). So it's illegal to enable the gpl flag (aka to enable x264/x265 and some
others libraries) along with the --nonfree flag (required for cuda/fdk-aac/etc)
and redistribute the same build. (it's perfectly fine for your own usage or if
kept in the same organisation). 
Having it shared or builtin isn't relevant at all.
If you redistribute such build, it will be a violation of the ffmpeg and others
developers rights.

Instead, we plan to redistribute a ffmpeg build with the gpl flag disabled. So
this package will be redistributed as "L"GPL instead of GPL. This build can be
redistributed even if we have activated few non-free dependencies.
At least that the plan to be discussed in the coming ffmpeg-nonfree review.
