I think you also need to update implementation of these operators to take
audio_share into account.

 
   bool is_null() const { return type == TYPE_NONE; }
   std::string ToString() const;
   static DesktopMediaID Parse(const std::string& str);
 
   Type type = TYPE_NONE;
 
   // The IDs referring to the target native screen or window.  |id| will be
   // non-null if and only if it refers to a native screen/window.  |aura_id|
   // will be non-null if and only if it refers to an Aura window.  Note that is
   // it possible for both of these to be non-null, which means both IDs are
   // referring to the same logical window.
   Id id = kNullId;
 #if defined(USE_AURA)
   // TODO(miu): Make this an int, after clean-up for http://crbug.com/513490.
   Id aura_id = kNullId;
 #endif

   // This id contains information for WebContents capture.
   WebContentsMediaCaptureId web_contents_id;
