Youtube player does not work on iOS

I have a problem here with youtube videos, I have it as a music player option on the website in the lower right corner, it works normal except on iOS mobile devices, what happens is that I can not play music.

Follow one of the sites that contains the player. site

player = new YT.Player(attrs.container, { 
    height: '200', 
    width: '200', 
    videoId: getIdFromUrl(videoUrl), 
    playerVars: { 
        html5: 1,
        enablejsapi: 1, 
        playsinline: 1 
        //origin: extraService.site_root_url.replace('http:', 'https:') 
        //origin: extraService.site_root_url 
    }, 
    events: { 
        'onReady': onPlayerReady, 
        'onStateChange': onStateChange 
    } 
});

This is the iframe it generates:

<iframe id="sdn-player" frameborder="0" allowfullscreen="1" title="YouTube video player" width="200" height="200" src="https://www.youtube.com/embed/2RtzSLLngc8?enablejsapi=1&amp;playsinline=1&amp;origin=https%3A%2F%2Fnoivos.casar.com"></iframe>
