Bootstrap 4 轮播和 youtube 视频

Question

我正在使用带有图像和嵌入 YouTube 视频的 Bootstrap 4 轮播。我设法在播放视频时暂停幻灯片，并在您按下控制按钮时停止视频。尽管通过按下控件查看或停止视频时，轮播循环不再自动工作，必须手动进行。有什么帮助吗？

我今天遇到了同样的问题！

   var done = false;
    function onPlayerStateChange(event) {
        if (event.data == YT.PlayerState.PLAYING) {
            $('#homepage-slider').carousel('pause');
            done = true;

            console.log('play'+YT.PlayerState.PLAYING);
        }
        if (event.data == YT.PlayerState.PAUSED) {
            console.log(YT.PlayerState.PAUSED);
            $('#homepage-slider').carousel('cycle');
        }
  }
