If I understand it correctly, this class will be used when USE_AURA is true but
USE_ASH is not, is this correct?

You may want to update the comments here and probably rename the class name to
DesktopCaptureDeviceAura.

Good point. I'll rename it in a separate CL.

     : public media::VideoCaptureDevice {
  public:
   // Creates a VideoCaptureDevice for the Ash desktop.
   static media::VideoCaptureDevice* Create(const DesktopMediaID& source);
 
   virtual ~DesktopCaptureDeviceAsh();
 
   // VideoCaptureDevice implementation.
   virtual void AllocateAndStart(const media::VideoCaptureParams& params,
                                 scoped_ptr<Client> client) OVERRIDE;
   virtual void StopAndDeAllocate() OVERRIDE;
 
  private:
   DesktopCaptureDeviceAsh(const DesktopMediaID& source);
 
   const scoped_ptr<class VideoCaptureDeviceImpl> impl_;
 
   DISALLOW_COPY_AND_ASSIGN(DesktopCaptureDeviceAsh);
 };
 
 
 }  // namespace content
 
 #endif  // CONTENT_BROWSER_RENDERER_HOST_MEDIA_DESKTOP_CAPTURE_DEVICE_ASH_H_
