Ubuntu下使用Live555搭建流媒体服务器

一、下载安装

wget  http://www.live555.com/liveMedia/public/live555-latest.tar.gz
tar -xzvf live555-latest.tar.gz
cd live
./genMakefiles linux-64bit 
make

二、运行 

cd mediaServer

./live555MediaServer

 

 可以看到，提示中有这么一句话：rtsp://192.168.10.201/<filename>。说明可以用rtsp协议来访问文件，试了一下，rtsp可以访问，http不行。

 

 三、测试

这里我在当前目录下创建一个video的文件夹，在文件夹里上传一个视频文件cat.mkv

客户端使用VLC，选择打开网络串流，在URL栏中填写：

rtsp://192.168.10.201/video/cat.mkv

 

点击播放后，出现了视频画面

 

网上有人说http也可以，然后我试了一下http地址：

报了以下错误

不确定是否是我的Live555的版本问题。

四、RTSP协议

测试了连接成功后播放、暂停/取消暂停、跳转到指定时间播放、停止播放，这四种情况，抓取数据包，抓包结果如下：

连接成功后播放：

没有做详细的分析，RTSP协议不了解，后续再看看。
