 VLC 2.2.6 is out with a few fixes (one of mine, even) and I stumbled
 across a patch that makes VLC works with FFmpeg >= 3.0 .

 I have been using this for a couple of days now and the resulting binaries
 seem to work just fine, but between my normal day-to-day use and
 exhaustive testing there's a quite a bit of a gap.

 Thus, I'm uploading a patch that disables/hides the `ffmpeg-VLC` subport
 but doesn't remove it completely yet, not until this version has seen more
 real-world usage in the wild.
