Comment (by rjvbertin@…):

 Well, this was less work and I had a bit more time than I thought . An
 initial "works-for-me" draft is available at

 https://github.com/RJVB/macstrop/tree/master/multimedia/VLC

 Could I ask you to have a look at the ffmpeg-VLC dependency list to see if
 it can be pruned a bit more?

 Two bits of collateral damage:
 - I had to drop opencv support, as opencv depends on ffmpeg and that would
 probably cause runtime issues (in addition to linker errors)
 - I didn't manage to tell the linker to use the libraries in
 ${prefix}/lib/vlc/ffmpeg/lib rather than in ${prefix}/lib . The pkg-config
 file is set up correctly though, so I guess the only solution would be to
 patch the build system to use absolute paths rather than `-lfoo`
 arguments. A bit over the top, I've simply registered a build conflict.
