Can not play mpeg-dash created with nginx-ts-module

[almoghzn]

Hi,

I'm trying to stream media using the nginx-ts-module. Everything looks fine (the index.mpd and mp4 filed are created under /var/media/dash) also browsing to the index.mpd url works fine, but trying to play this dash using Dash JavaScript Player doesn't work.

I'm using nginx-1.13.9 with nginx-ts-module.

My nginx configuration is (/usr/local/nginx/conf/nginx.conf): `user root; worker_processes 1;

error_log logs/error.log info;

pid /var/run/nginx.pid;

events { worker_connections 1024; }

http { include mime.types; default_type application/octet-stream;

sendfile        on;

keepalive_timeout  65;

server {
    listen 8000;

    location /publish/ {
        # This directive sets unlimited request body size
        client_max_body_size 0;

        ts;
        ts_hls path=/var/media/hls segment=10s;
        ts_dash path=/var/media/dash segment=10s;
    }

    location /play/ {
        types {
            application/x-mpegURL m3u8;
            application/dash+xml mpd;
            video/MP2T ts;
            video/mp4 mp4;
        }
        alias /var/media/;
    }
}

server {
    listen       80;
    server_name  localhost;

    location / {
        root   html;
        index  index.html index.htm;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
}

} `

My ffmpeg command to stream media to nginx is: ffmpeg -re -i "The LEGO Batman Movie - Trailer.mp4" -bsf:v h264_mp4toannexb -c copy -f mpegts http://{my_nginx_server_ip}:8000/publish/alilive

NOW. When I browse to http://{my_nginx_server_ip}:8000/play/dash/alilive/index.mpd I able to download the index.mpd. BUT, when I put this url in Dash JavaScript Player it is not playing the media.

On my nginx's error log I found a lots of this records: dropping unexpected TS packet pid:0x0011 But I read that I can ignore it here

One more thing, I also trying to stream live web cam recording instead of The LEGO Batman Movie - Trailer.mp4 using ffmpeg with the following command: ffmpeg -y -f dshow -i "video=Lenovo EasyCamera:audio=Microphone (High Definition Audio Device)" -bsf:v h264_mp4toannexb -c copy -f mpegts http://{my_nginx_server_ip}:8000/publish/alilive But when I execute this command I get: Codec 'mjpeg' (8) is not supported by the bitstream filter 'h264_mp4toannexb' Why?

1. What am I doing wrong?
2. As all seems to be working well, why DASH-ID player can't play my media?
3. How can I stream my video cam?

1. Is there any error in browser js console when playing the dash stream? Try increasing the segment size.
2. your webcam seems to send video in mjpeg codec rather than h264, you should transcode it to h264 with -c:v libx264
