  videohub writing software python

  Posted by Maurice Jansen on July 23, 2012 at 9:45 pm

  hi there all

  i’m trying to write a app in python to build
  a simple totalrecall program for our BM router.
  since it will be used for 3 shows every week with different
  router setup’s.

  i’m just starting programing in python and run into trouble.
  lack of knowledge i guess 😉

  i have it already running the dirty way with the terminal command

  nc 192.168.42.50 9990 < textfile.txt
  textfile.txt contains all route’s in the format described in the manual.
  this works but not all our operators are good in commandline foo 😉

  of coarse i can do it with a applescript too but want to make it in python
  crossplatform

  in python
  reading the setup on connecting to the router
  works ok.
  re sending this to the router works also.

  but rereading the router when route’s have changed
  is going wrong all the time due to polution in the
  input buffer are there any python guru’s here that can help me out.

  see code below

  import socket
  import struct, time
  import os
  from Tkinter import *
  import tkMessageBox

  HOST = “192.168.42.50”
  PORT = 9990
  #make socket and connect to BM router
  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  s.connect((HOST, PORT))
  #fill variables with all router settings
  header = s.recv(4096)
  setup = s.recv(4096)
  labelsin = s.recv(4096)
  labelsuit = s.recv(4096)
  locked = s.recv(4096)
  routes = s.recv(4096)

  def leesuit():
  #read routes out of the BM router
  #garbage = s.recv(4096)
  global routes
  s.send(“VIDEO OUTPUT ROUTING:nrnr”)
  #command to get routes again from the router
  routes = s.recv(4096)
  return

  def schrijfnaar():
  #send routes to the BM router
  #global routes
  s.send(routes)
  #garbage = s.recv(4096)
  print routes
  return

  gui =Tk()
  gui.title(“blackmagic total recall test”)
  gui.geometry(‘400×600+200+200’)
  button1 = Button(gui, text=”Read From MTX” , width=20,command=leesuit)
  button1.pack(padx=15,pady=15)
  button2 = Button(gui, text=”Send to MTX” , width=20,command=schrijfnaar)
  button2.pack(padx=15,pady=15)
  gui.mainloop()

  thanks in front if you can help

  sorry for the indention errors

  kind regards
  maurice
