视频很卡,播放不了,缓冲区突然很大,推流上不来,都有可能是带宽过低,SRS支持测试客户端到服务器的带宽。
SRS配置
SRS配置一般是单独加一个vhost支持测速。SRS的配置conf/bandwidth.conf
。譬如:
listen 1935;
vhost __defaultVhost__ {
}
vhost bandcheck.srs.com {
enabled on;
chunk_size 65000;
bandcheck {
enabled on;
key "35c9b402c12a7246868752e2878f7e0e";
interval 30;
limit_kbps 4000;
}
}
其中:
- key:服务器的key,若客户端给出的key和配置的不一致,断开连接。
- interval:测速的间隔,单位为秒,可为小数。若连续发起测速,时间间隔小于interval,服务器拒绝连接。
- limit_kbps:测速的最大带宽,即可以测出来的最大带宽,防止服务器收到攻击。
假设服务器的IP是:192.168.1.170
Flash测速工具
启动后用带宽测试客户端就可以查看:http://ossrs.net/srs.release/trunk/research/players/srs_bwt.html?server=192.168.1.170
备注:请将所有实例的IP地址192.168.1.170都换成部署的服务器IP地址。
检测完毕后会提示带宽,譬如:
检测结束: 192.168.1.170 上行: 1965 kbps 下行: 3631 kbps 测试时间: 6.0 秒
server:SRS 0.9.156 (github.com/ossrs/srs),
authors:winlin,wenjie.zhao, srs_id:123, srs_pid:32057, ip:192.168.1.170
测速库
我提供了AS和JS的库,可以直接调用来和服务器测速。
AS的库,直接拷贝文件SrsBandwidth.as
到工程,调用即可(参考注释说明):
- AS库对象:SrsBandwidth.as
- AS调用对象(主对象):srs_bwt.as,如何调用
SrsBandwidth.as
的实例。
JS的库,需要拷贝srs_bwt.swf
和srs.bandwidth.js
,调用方法参考js说明:
- JS库对象:srs.bandwidth.js
- JS调用对象(页面):srs_bwt.html,如何调用
srs.bandwidth.js
的实例。
备注:JS需要调用swf导出的js函数,由Flash发送RTMP包测速,因此js库依赖于as。可以导入Flex工程自己编译,或者使用已经编译好的srs_bwt.swf
Linux工具测速
另外,SRS还提供了带宽检测命令行工具:
[winlin@dev6 srs]$ cd objs/research/librtmp/
[winlin@dev6 librtmp]$ ./srs_bandwidth_check
RTMP bandwidth check/test with server.
Usage: ./srs_bandwidth_check <rtmp_url>
rtmp_url RTMP bandwidth url to check. format: rtmp://server:port/app?key=xxx,vhost=xxx
For example:
./srs_bandwidth_check rtmp://127.0.0.1:1935/app?key=35c9b402c12a7246868752e2878f7e0e,vhost=bandcheck.srs.com
./srs_bandwidth_check rtmp://127.0.0.1:1935/app?key=35c9b402c12a7246868752e2878f7e0e,vhost=bandcheck.srs.com>/dev/null
@remark, output text to stdout, while json to stderr.
直接执行将打印文本和json信息:
[winlin@dev6 librtmp]$ ./srs_bandwidth_check rtmp://127.0.0.1:1935/app?key=35c9b402c12a7246868752e2878f7e0e,vhost=bandcheck.srs.com
RTMP bandwidth check/test with server.
srs client librtmp library.
version: 0.9.158
bandwidth check/test url: rtmp://127.0.0.1:1935/app?key=35c9b402c12a7246868752e2878f7e0e,vhost=bandcheck.srs.com
simple handshake success
connect vhost/app success
bandwidth check/test success
SRS 0.9.158 (github.com/ossrs/srs), winlin,wenjie.zhao
127.0.0.1, 0.9.158, srs_pid=15264, srs_id=107
duration: 6395ms(3165+3148)
play: 3578kbps
publish: 4035kbps
terminate with ret=0
{"code":0,
"srs_server":"SRS 0.9.158 (github.com/ossrs/srs)",
"srs_primary_authors":"winlin,wenjie.zhao",
"srs_server_ip":"127.0.0.1",

"srs_id":107,
"duration":6395,
"play_duration":3165,
"play_kbps":3148,

可以只打印json信息,将stdout定向到/dev/null:
[winlin@dev6 librtmp]$ ./srs_bandwidth_check rtmp://127.0.0.1:1935/app?key=35c9b402c12a7246868752e2878f7e0e,vhost=bandcheck.srs.com>/dev/null
