  def caveats
    <<-EOS.undent
      Due to naming conflicts with other FFmpeg forks, this formula installs
      only static binaries - no shared libraries are built.

      The `ffprobe` program has been renamed to `ffprobe-bc` to avoid name
      conflicts with the FFmpeg executable of the same name.
