PIPEWIRE's Python controller (wrapper)

• ONLY AUDIO BY NOW [PR & FR WELCOME]
• STREAMING NOT SUPPORTED BY NOW

---

Python controller, player and recorder via pipewire's commands.

• Pipewire is a project that aims to greatly improve handling of audio and video under Linux. (Better than pulseaudio or jack)

Requirements

1. A Pipewire version installed (clean or via Pulseaudio) is needed, to check if you have pipewire installed and running, run this command, if the output is different, you'll need to install pipewire:

   1. Pipewire versions supported: 0.3.30, 0.3.32+

pw-cli info 0

# Example output
    id: 0
    permissions: rwxm
    type: PipeWire:Interface:Core/3
    cookie: 134115873
    user-name: "user"
    host-name: "user"
    version: "0.3.30" # Possibly more actual than this version
    name: "pipewire-0"
...

2. Python 3.7+
3. Ubuntu 20.04+

Install & Tutorial

Install

pip3 install pipewire_python # or pip

Tutorial

PLAY AND RECORD

from pipewire_python.controller import Controller

# [PLAYBACK]: normal way
audio_controller = Controller()
audio_controller.set_config(rate=384000,
                            channels=2,
                            _format='f64',
                            volume=0.98,
                            quality=4)
audio_controller.playback(audio_filename='docs/beers.wav')

# [RECORD]: normal way
audio_controller = Controller()
audio_controller.record(audio_filename='docs/5sec_record.wav',
                        timeout_seconds=5)

GET INTERFACES

from pipewire_python.controller import Controller

audio_controller = Controller()
# Return all Client Interfaces on Pipewire
audio_controller.get_list_interfaces(
    type_interfaces="Client",
    filtered_by_type=True,
)
# Return all interfaces
audio_controller.get_list_interfaces(
    filtered_by_type=False,
)

LINK PORTS

Linking Ports

from pipewire_python import link

inputs = link.list_inputs()
outputs = link.list_outputs()

# Connect the last output to the last input -- during testing it was found that
# Midi channel is normally listed first, so this avoids that.
source = outputs[-1]
sink = inputs[-1]
source.connect(sink)

# Fun Fact! You can connect/disconnect in either order!
sink.disconnect(source) # Tada!

# Default Input/Output links will be made with left-left and right-right
# connections; in other words, a straight stereo connection.
# It's possible to manually cross the lines, however!
source.right.connect(sink.left)
source.left.connect(sink.right)
