为什么我的视频无法播放并被暂停？

Question

在我的代码中，视频在准确的时间开始，但没有播放（视频暂停）。下一个视频在精确的时间开始。请查看我的代码：

var videoSources = new Array();
videoSources[0] = 'https://sample-videos.com/video123/mp4/720/big_buck_bunny_720p_1mb.mp4';
videoSources[1] = 'https://sample-videos.com/video123/mp4/720/big_buck_bunny_720p_2mb.mp4';
videoSources[2] = 'https://sample-videos.com/video123/mp4/720/big_buck_bunny_720p_5mb.mp4';

var timesToPlayVideos = new Array();
timesToPlayVideos[0] = "16:7";
timesToPlayVideos[1] = "16:9";
timesToPlayVideos[2] = "16:13";

var videoCount = videoSources.length;

function checkIfTimeForVideo() {
  var currentDateTimeStamp = new Date(),
    currentTimestamp = currentDateTimeStamp.getHours() + ":" + currentDateTimeStamp.getMinutes();
  console.log("currenttime", currentTimestamp);
  console.log("currenttime", currentDateTimeStamp);

  if (timesToPlayVideos.indexOf(currentTimestamp) > -1) {


    var arrayIndex = timesToPlayVideos.indexOf(currentTimestamp),
      videoSrcToPlay = videoSources[arrayIndex];
    console.log("arrayindexvalue", arrayIndex);
    var video = document.createElement("VIDEO");
    document.body.appendChild(video);
    video.setAttribute("src", videoSrcToPlay);
    console.log("video src", videoSrcToPlay);
    document.getElementById("myVideo").setAttribute("src", videoSrcToPlay);
    document.getElementById("myVideo").load();
    //console.log("This",videoSrcToPlay,"is playing");
    document.getElementById("myVideo").play();
    console.log("hello");
  }
}
console.log("Program start from here");
window.setInterval(checkIfTimeForVideo, 5000);

给我有关我的代码的任何建议。

谢谢
