Large Latency on DASH streaming

[kenanchristian]

I tried to stream using FFmpeg to the dash application, then I tried to play it using VLC. And it waits around 30secs to start playing, and it plays from the beginning, not the current timestamp.

This is my current config on the RTMP block

rtmp {
    server {
        listen 1935;

        application live {
            live on;

           exec ffmpeg -re -i rtmp://localhost:1935/live/$name
              -c:a libfdk_aac -b:a 32k  -c:v libx264 -b:v 128K -f flv rtmp://localhost:1935/hls/$name_low
              -c:a libfdk_aac -b:a 64k  -c:v libx264 -b:v 256k -f flv rtmp://localhost:1935/hls/$name_mid
              -c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 512K -f flv rtmp://localhost:1935/hls/$name_hi
              -c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 512K -f flv rtmp://localhost:1935/dash/$name_dash;
        }

        application hls {
             live on;

             hls on;
             hls_path /tmp/hls;
             hls_nested on;

             hls_variant _low BANDWIDTH=160000;
             hls_variant _mid BANDWIDTH=320000;
             hls_variant _hi  BANDWIDTH=640000;
        }

        application dash {
            live on;

            dash on;
            dash_path /tmp/dash;
            dash_nested on;
        }
    }
}

This is the command I use for streaming

ffmpeg -re -i 2014\ SPRING.mp4 -c copy -f flv rtmp://52.221.221.163:1935/dash/spring

How can I reduce the delay, and make it play from the same timestamp as the streamer? Can I achieve under 5s latency?

Having the same exact issue of the stream starting from the begining but the delay to start the stream is much much longer for me kn minutes. please share if you find the solution. Will do the same thanks

@saltpetreca I'm currently changing the playlist length and fragment length. It helps but still have maybe around 10sec latency

Thanks did you fix the issue with the stream starting from the beginning instead of the timestamp.

Regardless of what I try the stream starts from beginning.
