Video.js player width and height adaptive setting method

I've been looking for a long time and finally found it

<video id="my-video" class="video-js vjs-big-play-centered vjs-fluid" controls preload="auto" poster="" data-setup="{}">
    <source src="视频地址" type="video/mp4">
    <p class="vjs-no-js">要观看这个视频，请启用JavaScript，并考虑升级到一个Web浏览器<a href="http://videojs.com/html5-video-support/" target="_blank">支持HTML5视频</a></p>
</video>

vjs-fluidJust add it after class

<script type="text/javascript">
var player = videojs('#my-video',{fluid: true},function(){
    console.log('Good to go!');
    this.play(); // if you don't trust autoplay for some reason
})
</script>
