autoplay not working on mobile devices YouTube video - html

Question

The video is not working in autoplay on mobile, I know that the question has already been asked several times but the code was developed specifically for my site (by a developer who answers me more).
So I can't change it entirely, could I tell me what to add to make it work?
<script>
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {
playerVars: {
'autoplay': 1,
'controls': 0,
'autohide': 1,
'wmode': 'opaque',
'showinfo': 0,
'loop': 1,
'mute': 1,
//'start': 15,
//'end': 110,
'playlist': '{{ product.metafields.left_image.left_image[forloop.index0] }}'
},
videoId: '{{ product.metafields.left_image.left_image[forloop.index0] }}',
events: {
'onReady': onPlayerReady
}
});
}
function onPlayerReady(event) {
event.target.mute();
$('#text').fadeIn(400);
//why this? Well, if you want to overlay text on top of your video, you
//will have to fade it in once your video has loaded in order for this
//to work in Safari, or your will get an origin error.
}
//this pauses the video when it's out of view, just wrap your video in .m-//video
$(window).scroll(function() {
var hT = $('.m-video').height(),
wS = $(this).scrollTop();
if (wS > hT) {
player.pauseVideo();
}
else {
player.playVideo();
}
});
</script>

Answer 1

you can add the following code in the end of the onPlayerReady function:
if(window.innerWidth < 768) {
player.playVideo();
}
This code will start playing the video on mobile devices by checking the screen size.
