静音YouTube视频和自动播放

我已经做了一些工作,我正在尝试让页面上的YouTube视频自动启动并在页面加载时静音,这是我的HTML:

<div class="col-sm-8 product-video-section" id="player">
    <iframe id="ytplayer" width="560" height="315" src="https://www.youtube.com/embed/tMnpYFl6-k8" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen wmode="Opaque"></iframe>
</div>

JS:(我在谷歌上找到的)

<script>
        // 2. This code loads the IFrame Player API code asynchronously.
        var tag = document.createElement('script');

        tag.src = "https://www.youtube.com/iframe_api";
        var firstScriptTag = document.getElementsByTagName('script')[0];
        firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

        // 3. This function creates an <iframe> (and YouTube player)
        //    after the API code downloads.
        var player;
        function onYouTubeIframeAPIReady() {
            player = new YT.Player('player', {
                height: '195',
                width: '260',
                videoId: 'h3P1OR9gg2Y',
                events: {
                    'onReady': onPlayerReady,
                    'onStateChange': onPlayerStateChange
                }
            });
        }

        // 4. The API will call this function when the video player is ready.
        function onPlayerReady(event) {
            event.target.setVolume(0);
            event.target.playVideo();
        }

        // 5. The API calls this function when the player's state changes.
        //    The function indicates that when playing a video (state=1),
        //    the player should play for six seconds and then stop.
        var done = false;
        function onPlayerStateChange(event) {
            if (event.data == YT.PlayerState.PLAYING && !done) {
                //      setTimeout(stopVideo, 6000);
                done = true;
            }
            event.target.setVolume(0);
        }
    </script>

这几乎是我想要的方式,问题是它正在设置videoID并在JS中构建iframe-我不想这样,我有多个页面,使用这个模板有不同的视频,所以我需要在内容中具有iframe的能力。有没有一种不用设置id的方法?
