                          The nginx.conf is simple:

    sudo cat /usr/local/nginx/conf/nginx.conf    
    worker_processes  1; 
    error_log logs/error.log error;
    events {
        worker_connections  4096;
    }
    
    rtmp { 
        server { 
            listen 1935; 
            application live { 
                live on; 
                dash on; 
                dash_path /mnt/dash; 
                dash_fragment 15s; 
            } 
        } 
    } 
     
    http { 
        server { 
            listen 80; 
            location /dash { 
                root /mnt; 
            } 
        }
     
        types {
            text/html html;
            application/dash+xml mpd;
        } 
    }

I push the web camera to 127.0.0.1.

    output="rtmp://127.0.0.1:1935/live/sample"
    ffmpeg -f v4l2 -video_size 640x480 -i /dev/video0 -c:v libx264 -f flv $output

Pull it with rtmp protocol:

    ffplay  rtmp://127.0.0.1:1935/live/sample

Succeeded!

Pull it with dash protocol:

    ffplay  http://127.0.0.1/dash/sample.mpd 

It encounter an error:

    http://127.0.0.1/dash/sample.mpd : Invalid data found when processing input

How to fix it?    
My os :debian9.

    ffplay -formats |& grep "DASH Muxer"
      E dash            DASH Muxer
