This fix only for self hosted videos or videos using the WP Medialements.


Copy below code and paste/append it in WPLMS options panel - Footer - Google analytics code

  

jQuery(document).ready(function($){
  jQuery('.unit_content').on('unit_traverse',function(){ 
    $('video').each(function(){ 
          player = new MediaElementPlayer('video');
        $('video').on("play", function() {
            player.enterFullScreen();
        });
    });

  });
});

 


Result :


When user clicks on Play, the player would automatically open in full screen mode :
