input.pulseaudio usage in Linux with auto_null.monitor -> icecast stream. #3893

Closed Oliver-Mardle closed 5 months ago

Oliver-Mardle commented 5 months ago

How do I use the input.pulseaudio feature?

I keep getting either Error 2 or Error 5 and a large printout stating "this value has no method pulseaudio". I'm trying to use the dummy output auto_null.monitor - I can record from this in FFMPEG okay.

Below is my test file:

pulseDevice = "auto_null.monitor"
radio = input.pulseaudio(id="Tunnel", device=pulseDevice, clock_safe=false)

output.icecast(%ffmpeg(format="mp3", %audio(codec="libmp3lame", b="320k")),
  host = "localhost", port = 8000,
  password = "example", mount = "test",
  radio, fallible = true)

Hi @Oliver-Mardle,

To properly identify the root cause of the problem, I need to ask you a couple of questions:

  1. What operating system and version are you using?
  2. What version of liquidsoap are you using?
  3. How did you install liquidsoap?
  4. Can you upload the result of the liquidsoap --build-config command?

Hi @vitoyucepi

The OS is Ubuntu. Liquidsoap version is 2.2.4-1. I believe it was installed using apt install. Here's the build config - it looks as if pulseaudio is saying no... which is odd, as its definitely installed:

liquidsoap --build-config

Looks like it was built from opam. It doesn't resemble any of the common builds for ubuntu. I need some more info.

  1. To get the OS release, run cat /etc/lsb-release.
  2. To check if it was installed by apt run apt-cache policy liquidsoap.
