## 使用
zlm中的srt更加streamid 来确定是推流还是拉流，来确定vhost,app,streamid(ZLM中的)
srt中的streamid 为 `<vhost>/<app>/<streamid>?type=<push|play>& <other>=<other>`
zlm中的srt根据streamid 来确定是推流还是拉流，来确定vhost,app,streamid(ZLM中的)、
srt中的streamid 为 `#!::key1=value1,key2=value2,key3=value4......`
h,r为特殊的key,来确定vhost,app,streamid,如果没有h则vhost为默认值
m 为特殊key来确定是推流还是拉流，如果为publish 则为推流，否则为拉流 ,如果不存在m,则默认为拉流
其他key与m会作为webhook的鉴权参数
如：
#!::h=zlmediakit.com,r=live/test,m=publish
vhost = zlmediakit.com
app = live
streamid = test
是推流
- OBS 推流地址
`srt://192.168.1.105:9000?streamid=__defaultVhost__/live/test?type=push`
`srt://192.168.1.105:9000?streamid=#!::r=live/test,m=publish`
- ffmpeg 推流
`ffmpeg -re -stream_loop -1 -i test.ts -c:v copy -c:a copy -f mpegts srt://192.168.1.105:9000?streamid="__defaultVhost__/live/test?type=push"`
`ffmpeg -re -stream_loop -1 -i test.ts -c:v copy -c:a copy -f mpegts srt://192.168.1.105:9000?streamid=#!::r=live/test,m=publish`
- ffplay 拉流
`ffplay -i srt://192.168.1.105:9000?streamid=__defaultVhost__/live/test`
`ffplay -i srt://192.168.1.105:9000?streamid=#!::r=live/test`
- vlc 不支持,因为无法指定streamid[参考](https://github.com/Haivision/srt/issues/1015)

## usage
zlm get vhost,app,streamid and push or play by streamid of srt like this `<vhost>/<app>/<streamid>?type=<push|play>& <other>=<other>`
zlm get vhost,app,streamid and push or play by streamid of srt like this
`#!::key1=value1,key2=value2,key3=value4......`
h and r is special key,to get vhost app streamid, if h not exist ,vhost is default value
m is special key, to judge is push or pull, if vaule is publish the mode is push，otherwise is play, if m not exist, mode is play
other key and m ,can use by webhook to auth for play or push
like：
#!::h=zlmediakit.com,r=live/test,m=publish
vhost = zlmediakit.com
app = live
streamid = test
mode is push
- OBS push stream url
`srt://192.168.1.105:9000?streamid=__defaultVhost__/live/test?type=push`
`srt://192.168.1.105:9000?streamid=#!::r=live/test,m=publish`
- ffmpeg push
`ffmpeg -re -stream_loop -1 -i test.ts -c:v copy -c:a copy -f mpegts srt://192.168.1.105:9000?streamid="__defaultVhost__/live/test?type=push"`
`ffmpeg -re -stream_loop -1 -i test.ts -c:v copy -c:a copy -f mpegts srt://192.168.1.105:9000?streamid=#!::r=live/test,m=publish`
- ffplay pull
`ffplay -i srt://192.168.1.105:9000?streamid=__defaultVhost__/live/test`
`ffplay -i srt://192.168.1.105:9000?streamid=#!::r=live/test`
- vlc not support ,because can't set stream id [reference](https://github.com/Haivision/srt/issues/1015)
