I'm getting the following output from ffmpeg on the server, which appears to show it streaming to somewhere but I just can't connect.

netstat -a shows no port and scanning with 'nmap -p 4000-5000 172.20.0.75' shows no port open on the server. However this doesn't seem to work as the server doesn't appear to generate the port 1234 on the interface (172.20.0.75), i.e. The tutorials I've read so far reckon that ffplay can then connect and receive data using: To test, I'm running the following command which, as I understand it, should generate a tone and put it out on the LAN interface of the server on port 1234:įfmpeg -re -f lavfi -i aevalsrc='sin(400*2*PI*t)' -ar 8000 -f mulaw -f rtp rtp://172.20.0.75:1234 I also tried hw:0,2 as this was shown as an alternative device id by the command 'arecord -l'. Initially, I tried the following to try and feed input from a microphone for streaming:įfmpeg -ar 8000 -f alsa -i hw:0 -acodec mp2 -b:a 128k -f rtp rtp://172.20.0.75:1234īut this failed. My OS of choice is Debian 11 and I'm running ffmpeg. I'm trying to stream audio over a network from one building to another to save running an audio cable and have found numerous and varied tutorials on doing so.
