7.4 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.

例(7.4)-1：rtmp协议下的播放器调用代码示例

<script type="text/javascript">
var so = new SWFObject("/Player/CuSunPlayerV20_S.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");

so.addVariable("JcScpServer","rtmp://www.89525.net/vod"); //注意此处填入了rtmp流媒体服务器地址
so.addVariable("JcScpVideoPath","myfile.flv");
so.addVariable("JcScpImg","/player/Images/flashChangfa2.jpg");
so.addVariable("JcScpFile","/player/CuSunV2Set.asp");


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

例(7.4)-2：rtmp协议下的播放器调用代码示例

第一部分：

<script type="text/javascript" src="images/swfobject.js"></script>
<script type="text/javascript">
var so = new SWFObject("/Player/CuSunPlayerV20_S.swf","ply","520","325","9","#000000");
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>

第二部分,以下是配置文件CuSunV2Set.asp代码如下：

例(7.4)-3：http协议下的播放器调用代码示例

<script type="text/javascript">
var so = new SWFObject("/Player/CuSunPlayerV20_S.swf","ply","980","460","9","#000000");
so.addParam("allowfullscreen","true");
so.addParam("allowscriptaccess","always");
so.addParam("wmode","opaque");
so.addParam("quality","high");
