ruby-on-rails-3 – Rails 3：如何使Paperclip-FFMPEG正常工作？

> delayed_job 2.1.4
> delayed_pa??perclip 0.7.1
>回形针2.3.16
> paperclip-ffmpeg 0.7.0

(这种组合非常具体.一些较新的宝石不会与其他宝石一起使用.)

这是我的视频模型：

class Video < Upload
  has_attached_file :file,:default_style => :view,:processors => [:ffmpeg],:url => '/system/:class/:attachment/:id/:style/:basename.:extension',:path => ':rails_root/public/system/:class/:attachment/:id/:style' 
      + '/:basename.:extension',:default_url => '/images/en/processing.png',:styles => {
      :mp4video => { :geometry => '520x390',:format => 'mp4',:convert_options => { :output => { :vcodec => 'libx264',:vpre => 'ipod640',:b => '250k',:bt => '50k',:acodec => 'libfaac',:ab => '56k',:ac => 2 } } },:oggvideo => { :geometry => '520x390',:format => 'ogg',:convert_options => { :output => { :vcodec => 'libtheora',:acodec => 'libvorbis',:view => { :geometry => '520x390',:format => 'jpg',:time => 1 },:preview => { :geometry => '160x120',:time => 1 }
    }
  validates_attachment_content_type :file,:content_type => VIDEOTYPES,:if => Proc.new { |upload| upload.file.file? }
  process_in_background :file
end

创建带附件的新Video对象时,会保存原始对象,但不会进行任何转换.甚至调用Video.last.file.reprocess！除了返回真实之外,不会做任何事情. (在这种情况下,不确定“真实”是什么意思,因为它不起作用.)

我尝试在Paperclip :: options [：command_path]中硬编码ffmpeg的路径.我甚至尝试删除paperclip-ffmpeg.rb文件并将其替换为空白文件.真的以为我会通过做后来得到一个例外,相反,我只是再次“真实”.

感觉像paperclip-ffmpeg.rb正在加载,因为它是config / application.rb所需要的,但在尝试生成缩略图或转换视频时没有调用它.

谁能帮我这个？提前致谢！
