What is GetFrameRate and why? Make private or just put it in the cc file if it
does not need to be visible.

Calculates the frame rate of the fake device. We need a method because it needs
a calculation. I'll put it as private.

 
  private:
   // Flag indicating the internal state.
   enum InternalState {
     kIdle,
     kAllocated,
     kCapturing,
     kError
   };
   explicit FakeVideoCaptureDevice(const Name& device_name);
