op25 (boatbod) liquidsoap not mounting to icecast

[wgbecks]

I routinely run multiple instances of rx.py (separate feeds) of op25 and liquidsoap on Pi-4B's and SFF PCs imaged with Ubuntu. You just
have to be cognizant of the need to specify unique file names and port numbers for each of the instances of op25.

You can ignore the “URL” field in your output.icecast operators as they serve no real purpose. Just configure them as an empty set
in your liquidsoap scripts. IE: url=””

The following is a dump of active python process indicating the presence of four instances of op25 running on a Raspberry Pi-4B SBC.
My preference is to utilize rx.py whereby each instance runs separately as a system service that allows me to independently control, change,
or restart any particular instance (feed) without impacting any of the others.

No shown in the dump above, but I utilize NGINX configured as a reverse proxy to protect access to the op25 http consoles in that many
of my installations are remotely located and have to be managed and monitored over the Internet.

are you streaming with icecast or just local audio? My Pi is downstairs in the rack so local is no good for me. Building this for a friend that might want local audio as well as being a feed provider.

Also, I had no luck with liquidsoap working even with downgrading ffmpeg. So I just reimaged with Bullseye

I only install and configure Icecast as needed to support listening to my "Private" feeds but do utilize Liquidsoap in all cases to process
the UDP audio streams from OP25 regardless of the destination, be it Icecast or to BCFY. However, you can optionally script multiple
output.icecast operators if desired to provided streams to your own Icecast server(s) as well as to BCFY.

Yep. I'm learning that. I added -U just to make sure it was really working.
I built a new system on a RPi3b from scratch. I'm still learning multi-rx so in the meantime I'm running 2 instances of rx.py. I copied some of my known working files over and changed the rtl serial numbers and I have 2 streams functioning properly. However that was after I realized op25.liq had issues. In the output section there was an entry for URL. I copied the entries and noticed the IP address from my good setup was not the same IP is the Pi. I'm guessing that because it didn't resolve, it ignored it. During setup, I put in the current IP. I had the same issues with the mount points not showing up on Icecast. I removed that section entirely for both outputs and icecast is now functioning. User error 100%.

Now, however, I'm trying to get local audio and streaming. I went into op25.liq and uncommented, one at a time, the three LOCAL AUDIO OUTPUTS. Because there are two streams I have these two lines

input_A = mksafe(input.external(buffer=0.25, channels=2, samplerate=8000, restart_on_error=false, "./audio.py -x 2 -s -u 24680"))

and

input_B = mksafe(input.external(buffer=0.25, channels=2, samplerate=8000, restart_on_error=false, "./audio.py -x 2 -s -u 24690"))


I changed the (input) to either input_A or input_B.

On each of the local settings one of the systems would lockup with no tsbks. I went back in, commented it back out, rebooted and both streams function as desired.

I'm gonna dive back into the Pi4 with bookworm and the downgraded ffmpeg, fix op25.liq and see what happens, now that I know what the icecast problem was, then tackle multi. I would like to have 2 different webpages, as I have now, using two different ports for holding on talkgroups during incidents. I'm assuming that is possible in multi

Multi only provides for a single terminal page, but you click left/right to view each stream (aka 'channel') separately. In the curses terminal you use the left/right cursor keys. On the web terminal you use the little left/right arrows as indicated in the attached screenshot.

understood. thank you, and everyone else that helped
