-// information about available devices. The |device_id| of the descriptors can
-// subsequently be used to either obtain the supported formats for a device
-// using GetSupportedFormats(), or to create an instance of
-// VideoCaptureDeviceProxy using CreateDeviceProxy().
-// The factory guarantees that no two device descriptors it returns use the

-  // CreateDeviceProxy() is made. When a subsequent call is made while the
-  // |proxy_request| from a previous call has not yet been closed, the service
-  // "revokes" that previous |proxy_request| (by closing the connection) and the
-  // exclusive access goes to the new |proxy_request|.
-  // Note: This design avoids the issue of it not being clear how soon after a
-  // |proxy_request| has been (asynchronously) discarded a subsequent call to
-  // CreateDeviceProxy() would succeed if it were to deny access while still
-  // in use.
