我试图让Rails(3.0.0)在html5视频块中为iphone提供一个简单的m4v视频文件.出于理智的考虑,我正在使用来自http://camendesign.com/code/video_for_everybody的大巴克视频,我知道这些视频已正确编码为iphone并正常工作

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.

我已经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

任何人都有任何想法？
