试试这个:

    <video height="256" loop autoplay controls id="vid">
     <source type="video/mp4" src="video_file.mp4"></source>
     <source type="video/ogg" src="video_file.ogg"></source>

我通常都是这么做的。循环、控件和自动播放不需要值，它们是布尔属性。

我有一个案例，它与不同文件类型的顺序有关。试着改变一下，看看是否有帮助。

我的视频也出现了同样的问题

<video preload="none" autoplay="autoplay" loop="loop">
  <source src="Home_Teaser.mp4" type="video/mp4">
  <source src="Home_Teaser" type="video/webm">
  <source src="Home_Teaser.ogv" type="video/ogg">
</video>

经过搜索，我找到了一个解决方案:

如果我设置“preload”属性为“true”，视频正常启动

试试这个:

  <video width="320" height="240"  autoplay muted>
            <source src="video.mp4" type="video/mp4">
  </video>

其他的答案都对我没用。 我的解决办法是触发点击视频本身;Hacky(因为需要超时)，但它工作正常:

function startVideoIfNotStarted () {
    $(".id_of_video_tag").ready(function () {
        window.setTimeout(function(){
            videojs("id_of_video_tag").play()
        }, 1000);
    });
}
$(startVideoIfNotStarted);

一开始我只能播放所有可见的视频，但旧手机的表现不太好。现在我播放离窗口中心最近的视频，然后暂停其他视频。香草JS。你可以选择你喜欢的算法。
