I need to push living stream by `obs`, and cut living stream into ll-hls segment files. I read `wiki` and using next command to realize this mission:
```shell
gpac -i rtmp://localhost/live reframer:rt=on @ -o res/live.m3u8:segdur=10:cdur=1:profile=live:dmode=dynamic:llhls=sf
``` 
but `gpac`  output next message:
```shell
[FFDmx] Fail to open rtmp://localhost/live - error Input/output error
Failed to load filter for "rtmp://localhost/live": Feature Not Supported
```
I want to know where there is a way to create living stream by `obs` and generate ll-hls segment files? I read wiki and it's just using file as input, which is not true live stream and not people always wanto to do.
