HTML5实时显示摄像头视频

1、页面HTML代码：

<canvas id="video-canvas" style="width: 100%; height: 387px;"></canvas>

<script type="text/javascript" src="<%=basePath%>resources/js/jsmpeg-master/jsmpeg.min.js"></script>
<script type="text/javascript">
var canvas = document.getElementById('video-canvas');
var url = 'ws://' + document.location.hostname + ':' + port + '/';
port = port + 2;
var player = new JSMpeg.Player(url, {
canvas : canvas
});
</script>

2、需要Node做服务端，下载jsmpeg-master

npm install cnpm -g --registry=https://registry.npm.taobao.org

cnpm install ws -g

添加 NODE_PATH 和path 环境变量，路径是modules模块儿的所在路径，注意用户模块和全局安装模块儿的路径不同，根据需要选择，不设置服务器报错找不到模块module 

node D:\lang\nodejs\node_modules\jsmpeg-master\websocket-relay.js 123456 8981 8982
