这是我本地的代码，只修改了rtsp视频流的url
<b>视频投放线</b>
<video id="trailer" autoplay loop crossorigin controls>
<source src="rtsp://admin:password@192.168.1.64:554/h264/ch1/main/av_stream" type="application/x-rtsp">
</video>
<div style="margin: 10px 0px;">
<b>宽度：</b>
<input type="number" id="horizontal" min="1" step="1" value="20">
</div>
