            console.log('here it is');
            cues = aTextTrack.cues();   //subtitles content is here
            console.log('Ready State', aTextTrack.readyState()) 
            console.log('Cues', cues);
        });

        //this method call triggers the subtitles to be loaded and loaded trigger
        aTextTrack.show();
