ffmpeg exec command not running in nginx rtmp

evangeline123 commented 7 years ago

I am using nginx and rtmp module to stream live hls and mpeg-dash. here is my rtmp command in nginx .conf

rtmp {
server {
    listen 1936;

    application mypull {
    live on ;
    meta copy;
    allow play all;

    pull rtmp://184.72.239.149/vod/BigBuckBunny_115k.mov name=test live=1;

    exec_push   /usr/bin/ffmpeg -re -i rtmp://localhost:1936/mypull/$name -vcodec libx264 -acodec libmp3lame -f flv rtmp://localhost:1936/hls/$name;

}

application dash {
        live on;
        dash on;
        dash_path /tmp/dash;
        dash_nested on;
        dash_fragment 5s;
        dash_playlist_length 30s;
    }
     application hls {
        live on;
        hls on;
    hls_playlist_length 30s;
    hls_fragment 5s;
        hls_path /tmp/hls;
    }
}
}

but it is not playing. it seems that the ffmpeg command is not even running. and the hls and dash folders are empty. could anyone help me with it?

I have the same question, thanks!

Use a SH file.

Config: exec /opt/hls.sh $name;

Example SH File: ffmpeg -i rtmp://localhost/live/$1 -async 1 -vsync -1 -c:v libx264 -c:a ...

Works for me!

aamelegy commented 7 years ago

it could be nginx trying to run the command but fails for some reason, may be a missing codec for example. try running your command without nginx and see if it is working without errors

begetan commented 7 years ago

I am using directive exec_static in this case.

Just replace exec_push with above one. It will start streamig immediatelly aftere start nginx process.

sassyn commented 7 years ago

Did u manage to solve it?

Nothing works for me in terms of exec command;

server { listen 1935; ping 3m; ping_timeout 30s; notify_method get;

  application myapp {
     live on;
     exec_options on;

 exec_push /usr/bin/ffmpeg -i rtmp://localhost/src/$name -vcodec libx264 .... rtmp://localhost/hls/$name 2>>/var/log/ffmpeg-$name.log;
   exec_push /usr/bin/ffmpeg -version  > /tmp/xxxx;
   exec_pull /usr/bin/ffmpeg -version  > /tmp/xxxxsss;
   exec_static  /usr/bin/ffmpeg -version  > /tmp/xxxxsss;
   exec /usr/bin/ffmpeg -version  $name  >> /tmp/xxxxsss;
}

}

Nothing seems to work. I even run the nginx as root user.

I'm also compile with --debug

here is the nginx -v output:

Any idea? I'm running Ubuntu 16.04. Disable the apparmor. Nothing in the logs, or in dmesg/syslog.

zorrigas commented 7 years ago

Again, use a sh file, and parse name as argument.

exec /opt/hls.sh $name;

sassyn commented 7 years ago

It seems that the issue is with the NGINX version.

See here: https://github.com/arut/nginx-rtmp-module/issues/886

Here is working config for custom build version 1.11.10 and 1.10.1 on ubuntu:

rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 5000;

        application src {
            live on;
            sync 50ms;

What I'm doing wrong?

Hi all,

same with openresty 1.11.2.4 and rtmp module. compiled everything is fine, but not working when use exec_pull or exec_push .

They only works when you publish or play a stream on an application, for example: application myapp { live on; exec_push /usr/bin/ffmpeg -re -i rtmp://localhost/$app/$name -vcodec libx264 -acodec aac -strict -2 -f flv rtmp://localhost/hls/$name; }

application hls { live on; } When you publish a stream on myapp, then you can subscribe it on both myapp and hls. However, the stream on hls may be different from the stream on myapp, because it was transcoded.

vmintam commented 7 years ago

Hi winshining, this is my nginx rtmp config :

rtmp {
        server {
                listen 1935;
                chunk_size 4096;
        application myapp {
                  live on;
                  exec_push /usr/bin/ffmpeg -i /tmp/test.sdp -ar 44100 -vcodec libx264 -acodec libmp3lame -f flv rtmp://127.0.0.1:1935/live/testing;
                  }

                  application live {
                  live on;
                  }
        }       
}

when i use VLC join to rtmp://127.0.0.1/live/testing ---> nothing happen. but when i use command : ffmpeg -i /tmp/test.sdp -ar 44100 -vcodec libx264 -acodec libmp3lame -f flv "rtmp://127.0.0.1/live/testing"

everything is fine.

any suggestion for me ?

thanks!

I solved this problem by adding below in first line of nginx.conf. user root It's Ridha Ben Njima's answer.

winshining commented 7 years ago

@vmintam Try to push a stream to myapp, and then use vlc to join rtmp://127.0.0.1/live/testing. In fact, it's not suggested to use it as you set, the purpose of exec_push is to relay your push from one app to anohter:

rtmp {
    server {
        listen 1935;
        chunk_size 4096;
        application myapp {
            live on;
            exec_push /usr/bin/ffmpeg -re -i rtmp://127.0.0.1:1935/$app/$name -ar 44100 -vcodec libx264 -acodec libmp3lame -f flv rtmp://127.0.0.1:1935/live/testing;
        }

        application live {
            live on;
        }
    }
}

Then, you can push to myapp, play on live:)

I have the same problem - ffmpeg doesn't run when I start nginx. My question is: how would one find out what the error is? On my centos 6 server there's nothing in the console when I start nginx, I can't find an nginx log anywhere. I have a similar nginx.conf file as previous posts here and if ffmpeg won't start there must be a reason recorded somewhere. Thanks for any pointers.

same here. trying to run the following: exec_static /usr/bin/ffmpeg -re -i rtmp://localhost:1935/hls/$name -c:a libfdk_aac -b:a 32k -c:v libx264 -b:v 128K -f flv rtmp://localhost:1935/hls/$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 > /home/zsyed/Documents/logs.txt;

This is the issue, which I faced. Infact, redirecting the output of ffmpeg somewhere in /tmp can tell you the exact reasons. In my case, it was permission issue and it works fine. I am using as follow:

exec_push ffmpeg -i rtmp://localhost:1935/myapp/$name -c:v copy -c:a copy -segment_time 120 -f segment -reset_timestamps 1 -strftime 1 /opt/test_utils/$name_rtmp.mp4 2>>/tmp/ffmpeg.error;
