 // A new breed of mock media filters, this time using gmock!  Feel free to add
 // actions if you need interesting side-effects (i.e., copying data to the
 // buffer passed into MockDataSource::Read()).
 //
 // Don't forget you can use StrictMock<> and NiceMock<> if you want the mock
 // filters to fail the test or do nothing when an unexpected method is called.
