Serving rtmp on port 1935
22 mai 2020, par JJ The SecondI'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 :

1935/tcp ALLOW Anywhere
22/tcp (v6) ALLOW Anywhere (v6)
22 (v6) ALLOW Anywhere (v6)
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
