最近公司要测试流媒体性能,第一次接触,网上资料也很少,只有相互抄来抄去的4个函数介绍,研究2天,测试如下;
1.RTMP介绍略
flex_rtmp_connect Connects a client to an RTMP server and sets connection options.
flex_rtmp_disconnect Disconnects a client from an RTMP server.
flex_rtmp_send Sends messages to an RTMP server.
flex_rtmp_receive Receives responses from an RTMP server
2.制作测试脚本:测试协议选择Flex协议,Flex协议对RTMP支持;
配置协议:1.Run-times Settings(F4)-Flex-RTMP;在close all open RTMP*****选择,若不选择批量跑会报错【这个设置操作上应该等于flex_rtmp_disconnect函数】;
2.TOOLS-Recording Options(crtl+F7)-NetWork-Port Mapping 选择Socket level data 或者Soket level data and WinNet level data;
RTMP是通过1935端口建立的收发连接;
3.在LR帮助文档描述还需要设置下面内容,设置收发连接的字节;
In order to enable RTMP simulation, you must configure the recording options for the Flex protocol.
To enable RTMP:
1 Open the Recording Options dialog box by selecting Tools > Recording Options or clicking the Options button in the Start Recording dialog box.
2 In the Network > Port Mapping node click Options.
3 Set the Send-Receive buffer size threshold to 1500.
我理解应该是RTMP握手及后续请求每次是1536个字节

3.录制脚本;填写地址,点击播放,制作脚本
flex_rtmp_connect("connect_step0",
"Host=10.200.4.61:1935",
"Snapshot=tRTMP1.inf",
"ConnectionID=12",
MESSAGE,
"ChannelID=3",

"Argument=<arguments><string>connect</string><number>1</number><object>"

LAST);
flex_rtmp_receive("recv_step0",
"ConnectionID=12",
"Snapshot=tRTMP2.inf",
CHANNEL,
"ChannelID=2",
LAST);
flex_rtmp_receive("recv_step1",
"ConnectionID=12",
"Snapshot=tRTMP3.inf",
CHANNEL,
"ChannelID=2",
CHANNEL,
"ChannelID=2",
CHANNEL,
"ChannelID=3",
LAST);
flex_rtmp_send("send_step0",
"ConnectionID=12",
"Snapshot=tRTMP4.inf",
MESSAGE,
"ChannelID=2",
"DataType=server bw",
"StreamID=0",
"Argument=<arguments><xmlData><![CDATA[<string>\\x00LK@</string>]]></"
"xmlData></arguments>",
LAST);
flex_rtmp_send("send_step1",
"ConnectionID=12",
"Snapshot=tRTMP5.inf",
MESSAGE,
"ChannelID=3",
"DataType=flex message",
"StreamID=0",
"Argument=<arguments><string>createStream</string><number>2</number>"
"<null/></arguments>",
LAST);
flex_rtmp_send("send_step2",
"ConnectionID=12",
"Snapshot=tRTMP6.inf",
MESSAGE,
"ChannelID=2",
"DataType=ping",
"StreamID=0",
"Argument=<arguments><xmlData><![CDATA[<string"
">\\x00\\x03\\x00\\x00\\x00\\x00\\x00\\x00\\x03\\xe8</string>]]></"
"xmlData></arguments>",
LAST);
flex_rtmp_receive("recv_step2",
"ConnectionID=12",
"Snapshot=tRTMP7.inf",
CHANNEL,
"ChannelID=3",
LAST);
flex_rtmp_disconnect("disconnect_step0",
"ConnectionID=12",
LAST);//手动添加disconnect,录制时候一定会产生这个脚本
到此一个脚本部分内容如上,,脚本内容也比较简单,不过LR帮助文档也没有相关介绍,如果自己手动写不一定写出来;
需要注意是,一个音频文件脚本会建立几百次甚至上千次receive,因此脚本中wasted time较高,在批量运行也会包含浪费时间
Action.c(3181): Notify: Transaction "音频" ended with "Pass" status (Duration: 74.9486 Wasted Time: 9.3849).
以上只代表本人观点!
