一、html代码：
<video id="my-video" class="video-js" playsinline controls preload="auto" controlslist="nodownload" controlslist="nofullscreen" width="100%" height="240"
poster="upload/moviepic/2019-08-02/1564739500xyzp.png" data-setup="{}">
<source src="" type="video/mp4">
<source src="" type="video/ogg">
<source src="" type="video/webm">
<p class="vjs-no-js"> to view this video please enable javascript, and consider upgrading to a web browser that <a href="http://videojs.com/html5-video-support/" target="_blank">supports html5 video</a> </p>
</video>
二、javascript代码：
<script type="text/javascript">
var video = document.getelementbyid("my-video");
window.url = window.url || window.webkiturl;
var xhr = new xmlhttprequest();
var play_url = 'test.mp4';
xhr.open("get", play_url, true);
xhr.responsetype = "blob";
xhr.onload = function() {
if (this.status == 200) {
var blob = this.response;
console.log(blob);
video.onload = function(e) {
window.url.revokeobjecturl(video.src);
};
video.src = window.url.createobjecturl(blob);
}
}
xhr.send();
</script>
三、效果图如下：
