you need to propagate this exception as reverse dependency to the following packages:

- gst1-libav
- kodi
- minidlna
- mpd
- mpv
- opencv
- opencv3
- squeezelite
- tovid

Imho this is too much work, we should live with the build error and
bump ffmpeg to 3.0.2 after the next buildroot release to fix the
problem. On github you can test my patch series already:

https://github.com/bkuhls/buildroot/tree/ffmpeg3

The main problem is that vlc 2.2.x is incompatible with ffmpeg3, only
vlc master branch works, this branch will be released as vlc 3.0
sometime in the future. We would carry a pre-released version of vlc
in buildroot, which is something we want to avoid if possible.

Before the ffmpeg 3 vs. vlc problem arose I thought we could remove
the vlc warning in its Config.in:
https://git.busybox.net/buildroot/tree/package/vlc/Config.in#n2

When bumping to a pre-release version we should keep it ;)
