几个月来我一直在使用YouTube IFrame播放器API,并且最近在播放器加载时开始看到此异常: Uncaught ReferenceError: ytcfg is not defined 检查iframe,我看到成功调用yt.setConfig,但ytcfg.set稍后失败.API最近有变化吗？任何播放器参数都可能导致此问题？

<script src="//s.ytimg.com/yts/jsbin/www-embed-player-vflnzmqns/www-embed-player.js" type="text/javascript" name="www-embed-player/www-embed-player"></script>
<script src="//s.ytimg.com/yts/jsbin/player-en_US-vflr--npw/base.js" name="player/base"></script>
<script>
    yt.setConfig({
        ...
    });
    writeEmbed();
</script>
<script>
    ytcsi.info('st', 35);
    ytcfg.set({
        "TIMING_ACTION": "",
        "CSI_VIEWPORT": true,
        "TIMING_INFO": {
            "c": "WEB",
            "yt_li": 1,
            "cver": "1.20161112",
            "yt_lt": "cold"
        },
        "CSI_SERVICE_NAME": "youtube"
    });
    ;</script>

这个问题有几个变种:
