工程行业网站,网站流量用完了,网页制作与网站建设初学者必看教程,哈尔滨网站建设技术托管由于我也是刚开始接触这个东东#xff0c;原理什么的不是很清楚#xff0c;这里我就不说了#xff0c;免得误人子弟#xff0c;嘿嘿#xff01;第一步#xff0c;下载FlashMediaServer3.5#xff0c;网上有很多资源#xff0c;这里就不提供了#xff0c;大家google一下…由于我也是刚开始接触这个东东原理什么的不是很清楚这里我就不说了免得误人子弟嘿嘿第一步下载FlashMediaServer3.5网上有很多资源这里就不提供了大家google一下就可以了这里给一个序列号1373-5209-5319-9982-4515-7002我用地就是这一个。安装完后打开FlashMediaServer3.5服务一个是Start Adobe Flash Media Server 3.5.2另一个是Start Flash Media Administration Server 3.5.2。第二步在FlashMediaServer3.5安装目录下的applications文件夹下新建一个测试文件夹“tests”。这个文件夹后面会用到。第三步下载Flex Builder 3地址我也不提供了网上google一下有很多资源的。安装Flex Builder3第四步编写录音录像程序MyTest。这里的代码是从网上扒的。原文地址http://hi.baidu.com/xulina809/blog/item/6d456db603fb90788bd4b200.html 其中修改了一下我服务器的地址具体代码如下View Code?xml version1.0 encodingutf-8?mx:Application xmlns:mxhttp://www.adobe.com/2006/mxml layoutabsolute creationCompleteplayinit() width366 height350 mx:Script![CDATA[import mx.events.SliderEvent;import mx.events.VideoEvent;import mx.collections.ArrayCollection;import mx.rpc.events.ResultEvent;import mx.core.UIComponent;import flash.events.StatusEvent;import flash.events.SecurityErrorEvent;import flash.media.Camera;import flash.media.Microphone;import flash.net.NetConnection;//由于fms使用的是amf0而flex3中的as3默认使用的是amf3.所以要让flex使用AFM0NetConnection.defaultObjectEncoding flash.net.ObjectEncoding.AMF0;//视频服务端地址private var _videoServerURL:String rtmp://192.168.2.105/tests;private var _camera:Camera;
