Hi all,
I'm very new to the space and just getting started. I've appreciated the resources here in the forums but I seem to have a problem that I've been struggling with for the past several hours. I have a RTL-SDR V3 hooked up to my Raspberry Pi 3B+ and have gone through the steps from here to get it all set up. Ultimately I'm trying to be able to listen in to trunked radio signals, so I installed op25, liquidsoap, and icecast2. After tweaking with the parameters and troubleshooting other things all day I've got as far as being able to see the trunked signals come in and even have a stream from the icecast2 going with some information coming from op25. I've been really stumped at how I'm able to see some metadata come in to my media player running on my windows machine on the local network but cannot for the life of me get the audio to actually play! I've tried opening the stream on VLC on my phone as well and still have the same problem. I can't hear anything through the stream at all even when op25 is clearly receiving signals.
This is the command I used most recently
My ./op25.liq looks like this
When I run liquidsoap this is my log:
My /var/log/icecast2/error.log looks like this
My meta.json looks like this:
If anyone here has any ideas on what I can try to help troubleshoot the problem, I'd really appreciate as I'd hate to give up on this when I'm so close to the finish line...
🙏
