Variant bitrate streaming config

[zareef]

I am trying to show three variant bitrate streams from nginx. Source bitrate stream is ok but where can i find the multi bitrate playlist. Is there any problem with my config file? Here is my nginx.conf

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}

rtmp {
    server {
        listen 1935;

        application live {
             allow publish all;
             allow play all;
             live on;

             exec ffmpeg -i rtmp://localhost/show/$name
                        -c:v libx264 -c:a libfdk_aac -b:v 256k -b:a 32k
                        -f flv rtmp://localhost/show/$name_low
                        -c:v libx264 -c:a libfdk_aac -b:v 768k -b:a 96k
                        -f flv rtmp://localhost/show/$name_mid
                        -c:v libx264 -c:a libfdk_aac -b:v 1024k -b:a 128k
                        -f flv rtmp://localhost/show/$name_high
                        -c copy -f flv rtmp://localhost/show/$name_src;
        }

        application show {
            live on;
            hls on;
            hls_path /mnt/hls;
            hls_fragment 15s;

            hls_variant _low BANDWIDTH=320000;
            hls_variant _mid BANDWIDTH=960000;
            hls_variant _hi  BANDWIDTH=1280000;
           
        }

    }
}

        location /stat {
            rtmp_stat all;
            rtmp_stat_stylesheet stat.xsl;
        }
        location /stat.xsl {
            root html;
        }
    }
}

Where can i find my multi bitrate playlist file.
Thanks.
