Question

我正在尝试让Rails（3.0.0）在html5视频块中为iphone提供一个简单的m4v视频文件。为了理智，我正在使用来自http://camendesign.com/code/video_for_everybody的大降压兔子视频，我知道它已经正确编码为iPhone和工作

当我在Apache服务器上运行它时，它运行得很好。但是在我的rails dev环境中，它只是加载一个带有斜线的黑盒子。我的直觉告诉我它必须是某种类型的哑剧问题。

我已尝试将这些行添加到我的mime_types.rb文件中：

Mime::Type.register "video/mp4", :mp4
Mime::Type.register "video/mp4", :m4v

Rack::Mime::MIME_TYPES.merge!({
  ".ogg"     => "application/ogg",
  ".ogx"     => "application/ogg",
  ".ogv"     => "video/ogg",
  ".oga"     => "audio/ogg",
  ".mp4"     => "video/mp4",
  ".m4v"     => "video/mp4",
  ".mp3"     => "audio/mpeg",
  ".m4a"     => "audio/mpeg"
})

但没有运气。有人建议将此行添加到mime_types文件中

MIME :: Type.add（MIME :: Type.from_array（“video / mp4”，％（m4v））

但是这导致了这个错误：

NameError: uninitialized constant MIME
    from (irb):4
    from /Users/theshaolinmonk/.rvm/gems/ruby-1.9.2-p0@rails3/gems/railties-3.0.0/lib/rails/commands/console.rb:44:in `start'
    from /Users/theshaolinmonk/.rvm/gems/ruby-1.9.2-p0@rails3/gems/railties-3.0.0/lib/rails/commands/console.rb:8:in `start'
    from /Users/theshaolinmonk/.rvm/gems/ruby-1.9.2-p0@rails3/gems/railties-3.0.0/lib/rails/commands.rb:23:in `<top (required)>'
    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

有人有任何想法吗？

也许将以下行添加到您的Gemfile中？

gem 'mime-types', :require => 'mime/types'
