Force HLS variant playlist

[alphacentauri82]

So i am trying to limit consumption of MAX 256 per client. I have set the parameters accordingly:

`

    exec ffmpeg -i rtsp//myencoder/name 
    -c:a libfdk_aac -b:a 16k -c:v libx264 -b:v 64K -f flv rtmp://myip/live/name_low
    -c:a libfdk_aac -b:a 32k -c:v libx264 -b:v 128k -f flv rtmp://myip/live/name_mid
    -c:a libfdk_aac -b:a 64k -c:v libx264 -b:v 256K -f flv rtmp://myip/live/name__hi;

        # Turn on HLS
        hls on;
        hls_path /tmp/hls/;
        hls_fragment 3;
        hls_playlist_length 10;

        hls_variant _low BANDWIDTH=80000;
        hls_variant _mid BANDWIDTH=160000;
        hls_variant _hi BANDWIDTH=320000;

   `

But i get on the client 1.5 mbps output :( i need to reduce bandwith output of each stream to a top of 256 max... and these parameters clearly don't work.

Do HLS fragments fill up to 1.5 mbps? Just look at fragment files at check the sizes.

The adaptative stream doesn't work. I checked even if the encoder connection sends properly and what i get on the client side is a linear consumption with peaks up to 2-3mb. I saw that the fragment sizes can vary from 200k to 3mb. I don't know what parameter i have to change to 1. get the m3u8 to be 100% adaptative and also reduce the fragment sizes
