python-osc

Open Sound Control server and client implementations in pure python (3.4+).

https://travis-ci.org/attwad/python-osc.svg?branch=master

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/asyncio 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

"""Small example OSC 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=5005,
      help="The port the OSC server is listening on")
  args = parser.parse_args()

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

  for x in range(10):
    client.send_message("/filter", random.random())
    time.sleep(1)

Simple server

"""Small example OSC server

This program listens to several addresses, and prints some information about
received packets.
"""
import argparse
import math

from pythonosc import dispatcher
from pythonosc import osc_server

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

def print_compute_handler(unused_addr, 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("/filter", 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()
