i want to share audio over network so that i can use my tv as a wireless speaker. so i chose obs studio to make a stream out of my system audio coz i had it installed already. i went to settings -> output (advanced) -> recording (custom) and set ffmpeg output to output to url and set the url to udp://192.168.43.87:8081 and set container format to mp3 just to get started. so to test things out i ran mpv udp://192.168.43.87:8081 on the same machine and it plays audio. but when i tried accessing it from my android phone with mpv client, it doesnt play the audio, it just shows black screen for while and return to main menu of mpv app. thanks in advance.

iptables:

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere            
ACCEPT     udp  --  anywhere             anywhere            

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

solution

I set the sender’s IP address as output URL in obs studio, thats the issue. To fix this, set the receiver’s IP address as output URL. Yeah you can’t broadcast with this ig.

    thanks for help. i tried adding firewall rules to allow all udp connections (added my iptables output in the op), but no luck :(

      Yeah your iptables is already set to up ACCEPT by default meaning no blocking.

      My next step would be to determine whether the traffic is reaching the target machine. Look into how you can monitor inbound traffic and verify whether the server even sees the inbound connection attempt

        yeah thats the first thing i wanted to check. im not a network expert but i think my phone tried connecting to my machine. on the log, SRC=192.168.43.60 is my mobile phones address, but I cannot confirm it was a success or not.

        ive created a pastebin here just in case.

          There is no traffic on Port 8081 in those logs

              I mean to say that the connection attempt is failing because the traffic is never reaching the server.
