ruby-on-rails - FFmpeg 与 Ruby 联动

Question

我收到此错误：

Failed encoding. Errors: no output file created. Full output: dyld: Library not loaded: /usr/local/lib/libogg.0.dylib
 Referenced from: /usr/local/bin/ffmpeg
 Reason: Incompatible library version: ffmpeg requires version 9.0.0 or later, but libogg.0.dylib provides version 6.0.0

我已经通过 brew 安装了 ffmpeg，并安装了“ffmpeg”gem 和“streamio-ffmpeg”gem。

跑步：

otool -L /usr/local/lib/libogg.0.dylib

给我这个输出：

/usr/local/lib/libogg.0.dylib:
    /usr/local/lib/libogg.0.dylib (compatibility version 9.0.0, current version 9.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)

我在其中使用 ffmpeg 的文件如下所示：

# lib/carrierwave/ffmpeg.rb
require 'streamio-ffmpeg'
module CarrierWave
  module FFMPEG
    module ClassMethods
      def resample( bitrate )
        process :resample => bitrate
      end
    end

    def resample( bitrate )
      directory = File.dirname( current_path )
      tmpfile   = File.join( directory, "tmpfile" )

      FileUtils.mv( current_path, tmpfile )

      file = ::FFMPEG::Movie.new(tmpfile)
      file.transcode( current_path, :audio_bitrate => bitrate)

      File.delete( tmpfile )
    end
  end
end
