Why does the factory method take these args? They seem unexpected for something
that will validate either a particular file, or files in general.

There is a comment explaining the args in the parent class.  Added a comment to

+            const base::FilePath& platform_path) OVERRIDE;
+ private:
+  DISALLOW_COPY_AND_ASSIGN(MediaFileValidatorFactory);
+};
