做过流媒体压力测试的走过来

dragon-pk · 发表于 2008-9-1 17:17:24

现在我录制了vlc脚本文件，可以编译通过，现在我想测试它的性能，也就是说要是循环的话能够跑多久，做过流媒体测试都知道发收命令内容中有cesq，我没有对其参数化，但是我想参数化cesq，不知道如何下手？现在我action的内容是：

前面参考了对流媒体服务器达尔文进行性能测试的总结一文，但是对其while循环中的    while (a=1)

      {
                  lr_think_time(60);
      lrs_send("socket1", "buf8", LrsLastArg);
      }
buf8如下：
send buf8 252
      "PLAY rtsp://192.168.0.7/sugar.3gp RTSP/1.0\r\n"
      "CSeq: <b>\r\n"
      "Range: npt=0.000000-134.200000\r\n"
      "x-prebuffer: maxtime=2.000000\r\n"
      "x-transport-options: late-tolerance=10\r\n"
      "Session: <newsession>\r\n"
      "User-Agent: QuickTime/7.0.2 (qtver=7.0.2;os=Windows NT 5.0Service Pack 4)\r"
      "\n"
      "\r\n"
不明白  buf8怎么内容是那个？

大家谁做过？请指教！
