4.11 RTMP协议

　　RTMP(Real Time Messaging Protocol)实时消息传送协议是Adobe Systems公司为Flash播放器和服务器之间音频、视频和数据传输 开发的私有协议。
本款阳光播放器v2版，支持rtmp协议，并且在rtmp协议下，可以实现任意点的拖动(无须像http下那样，必须缓冲后的进度条中才可以拖动播放)。在rtmp下，阳光v2的使用方式：只须设置JcScpServer服务器参数，即写上服务器地址即可，很方便，其它代码不变。
简要的说：在rtmp下，JcScpServer的服务器地址参数值，请对应的填入您的服务器地址；在http下，JcScpServer的值，必须为空.

以FMS软件为例，如下图，它有两个地地址，一个是server服务器地址，一个是stream发布点称：

<script type="text/javascript" src="/player/images/swfobject.js"></script>
<div class="video" id="CuPlayer"> <b> <img src="/player/images/loading.gif" /> 网页视频播放器加载中，请稍后...</b> </div>
<script type="text/javascript">
var so = new SWFObject("/Player/player.swf","ply","980","460","9","#000000");
so.addParam("allowfullscreen","true");
so.addParam("allowscriptaccess","always");
so.addParam("wmode","opaque");
so.addParam("quality","high");
so.addParam("salign","lt");
<!-- HTML代码参数/Begin -->
so.addVariable("JcScpServer","rtmp://www.cuplayer.com/live"); //服务器地址
so.addVariable("JcScpVideoPath","livestream"); //发布点名称
so.addVariable("JcScpImg","/player/Images/flashChangfa2.jpg");
so.addVariable("JcScpFile","/player/CuSunV2Set.asp");
<!-- HTML代码参数/End -->

so.write("CuPlayer");
</script>

<script type="text/javascript" src="/player/images/swfobject.js"></script>
<div class="video" id="CuPlayer"> <b> <img src="/player/images/loading.gif" /> 网页视频播放器加载中，请稍后...</b> </div>
<script type="text/javascript">

so.addParam("allowfullscreen","true");
so.addParam("allowscriptaccess","always");
so.addParam("wmode","opaque");
so.addParam("quality","high");
so.addParam("salign","lt");
so.addVariable("JcScpFile","/Player/CuSunV2Set.asp");
so.write("CuPlayer");
</script>
