Comment (by RJVB):

 Nothing to be done about that unless/until VLC starts supporting FFMpeg 4,
 port:ffmpeg is reverted to FFMmpeg3 or an FFMpeg3 port is provided as a
 stop-gap measure for more conservative projects (port:mlt is concerned too
 here, and so might Audacity?). The FFMpeg 3 support was already hacked
 into VLC 2.2x.

 I see that VLC 3.0.2 is out but I cannot seem to find a clear indication
 what FFMpeg versions it supports. VLC does have an option to build its own
 FFMpeg copy with its own patches; I might just use that to avoid future
 breakage.

 [rant]
 Was it really necessary to update to an ABI and API breaking x.0.0 version
 instead of waiting a few patch or minor releases so that dependent
 projects can (could) catch up?
 A port:ffmpeg-devel would make perfect sense here (there used to be one
 IIRC).
