Serving rtmp on port 1935

Question

I've been trying to get ffmpeg to stream in rtmp but connection to port 1935 is always refused. I really don't know what else I can do to allow this connection.

Here is what specs I'm running.

• Ubuntu 18.04 (tried with 19.04) however same issue - here is why I think I've made a mistake
• No Nginx installation at the moment
• FFMPEG "ffmpeg version 3.4.6-0ubuntu0.18.04.1 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 7 (Ubuntu 7.3.0-16ubuntu3)"

This is the script I run:

ffmpeg -i "test.mp4" -c:v copy -c:a copy -f flv "rtmp://127.0.0.1/stream/test"

Error I get is:

[tcp @ 0x55ff05ab8ce0] Connection to tcp://127.0.0.1:1935 failed: Connection refused

I've done some research and been across many posts about ffserver.conf and I have made those changes but still no luck. Here is my config file. I also have ran ffserver once using this config.

Here is my ufw status:

--                         ------      ----
22/tcp                     ALLOW       Anywhere
22                         ALLOW       Anywhere

1935/tcp (v6)              ALLOW       Anywhere (v6)

but still nothing, I've also opened ports in iptables but no luck. Here is how this is done:

iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 1935 -j ACCEPT

and

iptables -A OUTPUT -m state --state NEW -m tcp -p tcp --dport 1935 -j ACCEPT

and still nothing, every time I run ffmpeg I get connection refused. I have previously installed nginx just to test but no luck.

What am I doing wrong here? Isn't this port suppose to be open now?

Thanks

I figured it out, I was using Nginx RTMP module - Nginx RTMP for some reason doesn't work well on Ubuntu but fine with Alpine 3.8 - As soon as I started a nginx rtmp docker container and exposed 1935 and 80 everything started working fine. Listen learnt, never install nginx rtmp module on ubuntu.
