With IFrame API, whether a video is played with html5 container or flash container depends on a lot of factors. I'm wondering: is it possible to set some parameter or call a function to force the player to be flash(or html5)?
besides, rel=0 seems not work in Iframe API, when I set it to 0, the related videos are still shown, is there something wrong with my code? thanks!
  player = new YT.Player('player', {
      height: '300', //720
      width: '400', //1280
      videoId: 'S2Rgr6yuuXQ',  
      playerVars: { 'rel': 0 }, // or rel: 0, rel: '0', all don't work
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange,
        'onError': onErrorDetected,
        'onPlaybackQualityChange': onQualityChange
        }
      });
