   // Since main context requires a bunch of input params, if these get called
   // multiple times, either multiple main contexts should be supported/managed
   // or the input params need to be the same as before.  So to be safe,
   // the CreateMainGetter function currently DCHECK to make sure it is not
   // called more than once.
   // The media and system getters however, do not need input, so it is actually
   // safe to call these multiple times.  The impl create only 1 getter of each
   // type and return the same instance each time the methods are called, thus
   // the name difference.
