python-osc 1.3

Open Sound Control server and client implementations in pure Python

Latest Version: 1.4

Open Sound Control server and client implementations in pure python (3.3+).

Current status

This library was developped following the specifications at http://opensoundcontrol.org/spec-1_0 and is currently in a stable state.

Features

  • UDP blocking/threading/forking server implementations
  • UDP client
  • int, float, string, blob OSC arguments
  • simple OSC address<->callback matching system
  • extensive unit test coverage
  • basic client and server examples

Installation

python-osc is a pure python library that has no external dependencies, to install it just use pip (prefered):

$ pip install python-osc

or from the raw sources for the development version:

$ python setup.py test
$ python setup.py install

Examples

Simple client

"""
This program sends 10 random values between 0.0 and 1.0 to the /filter address,
waiting for 1 seconds between each value.
"""
import argparse
import random
import time

from pythonosc import osc_message_builder
from pythonosc import udp_client


if __name__ == "__main__":
  parser = argparse.ArgumentParser()
  parser.add_argument("--ip", default="127.0.0.1",
      help="The ip of the OSC server")
  parser.add_argument("--port", type=int, default=8000,
      help="The port the OSC server is listening on")
  args = parser.parse_args()

  client = udp_client.UDPClient(args.ip, args.port)

  for x in range(10):
    msg = osc_message_builder.OscMessageBuilder(address = "/filter")
    msg.add_arg(random.random())
    msg = msg.build()
    client.send(msg)
    time.sleep(1)

Simple server

import argparse
import math

from pythonosc import dispatcher
from pythonosc import osc_server

def print_volume_handler(args, volume):
  print("[{0}] ~ {1}".format(args[0], volume))

def print_compute_handler(args, volume):
  try:
    print("[{0}] ~ {1}".format(args[0], args[1](volume)))
  except ValueError: pass

if __name__ == "__main__":
  parser = argparse.ArgumentParser()
  parser.add_argument("--ip",
      default="127.0.0.1", help="The ip to listen on")
  parser.add_argument("--port",
      type=int, default=5005, help="The port to listen on")
  args = parser.parse_args()

  dispatcher = dispatcher.Dispatcher()
  dispatcher.map("/debug", print)
  dispatcher.map("/volume", print_volume_handler, "Volume")
  dispatcher.map("/logvolume", print_compute_handler, "Log volume", math.log)

  server = osc_server.ThreadingOSCUDPServer(
      (args.ip, args.port), dispatcher)
  print("Serving on {}".format(server.server_address))
  server.serve_forever()
