hls_variant is not working for some unknown reason.

[kmskrishna]

From my knowledge the src application takes the rtmp stream from OBS with the in OBS as rtmp://10.9.21.50/src/1080 where 1080 is the name of the stream.

and then ffmpeg encodes it and feeds it to live application. But on starting the stream only /tmp/live folder is created /tmp/live/1080/ folder is not getting created and index.m3u8 is not getting created in that.

I have been googling for the solution for the past 48 hours but no luck. I am copy pasting my nginx.conf file here.
