/**

/*
 According to :: http://dev.w3.org/html5/spec-author-view/video.html#mediaerror
 We should never be creating these objects, we should just implement the interface
 which has 1 property for an instance, 'code'

 instead of doing :
    errorCallbackFunction( new MediaError(3,'msg') );
we should simply use a literal :
    errorCallbackFunction( {'code':3} );
