nit: We should make this interface pure virtual and provide default and fake
implementations.

I think it's better to do it in a separate CL.

  private:
-  // Used to capture audio to deliver to clients.
-  scoped_ptr<AudioCapturer> audio_capturer_;
-
   // Executes input and clipboard events received from the client.
   scoped_ptr<EventExecutor> event_executor_;
 
   // Used to capture video to deliver to clients.
   scoped_ptr<VideoFrameCapturer> video_capturer_;
 
   DISALLOW_COPY_AND_ASSIGN(DesktopEnvironment);
 };
