Where are options or transports defined?

I added a comment to describe the list of options supported. They are defined in
media/cast/net/cast_transport_sender_impl.h.

transportId is created by cast.streaming.session.create().

+    [nocompile] static void setOptions(long transportId,
+                                       object options);
   };
 };
