Shouldn't you include be "ui/gfx/display.h" here 
and "ui/gfx/display_observer.h" in 
video_capture_device_chromeos.cc ?

Actually, I can just forward declare Display.  Done.

+
+namespace media {
+
+class VideoCaptureDeviceChromeOS : public VideoCaptureDeviceLinux {
+ public:
+  explicit VideoCaptureDeviceChromeOS(const Name& device_name);
+  virtual ~VideoCaptureDeviceChromeOS();
+
+  void SetDisplayRotation(const gfx::Display& display);
+
+ private:
+  class ScreenObserverDelegate;
+
+  scoped_refptr<ScreenObserverDelegate> screen_observer_delegate_;
+  DISALLOW_IMPLICIT_CONSTRUCTORS(VideoCaptureDeviceChromeOS);
+};
+
+}  // namespace media
+
+#endif  // MEDIA_VIDEO_CAPTURE_LINUX_VIDEO_CAPTURE_DEVICE_CHROMEOS_H_
