Hi

I'm working on a multi-room audio addon which is giving me a headache. I'm relatively new to python which i'm sure is part of the problem.

Problem:
htpc 1 running my my addon in listener mode waits for udp note

htpc 2 running same addon in master mode will when it's started send udp data containing the path of the current playing song and the seektime in fractional seconds.

I suspected that htpc 1 wouldn't be playing slighty delayed to htpc 2 because of network lag and loading etc but htpc 1 is acctually ahead by 1-1.5 seconds which doesn't make any sense to me! Hope you can help explain this

Code:

def ListenForOrders():
    notification("soundway", "Awaiting your commands", 3000, __settings__.getAddonInfo("icon"))
    while 1:
        server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        server_socket.bind(("", 1337))
        data, address = server_socket.recvfrom(256)
        datastring = str(data)
        dataarray = datastring.split("|")
        if dataarray[0] == "soundway":
            if xbmc.getInfoLabel("Player.Filenameandpath") != dataarray[1]:
                xbmc.Player().play(str(dataarray[1]))
            seektime = float(dataarray[2])+((time.time()+OFFSET)-float(dataarray[3]))
            xbmc.Player().seekTime(seektime)      
                
def GiveOrders():
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    timetosend = time.time()+OFFSET
    data = 'soundway|' + xbmc.getInfoLabel("Player.Filenameandpath") + '|' + str(xbmc.Player().getTime())+"|"+str(timetosend)
    client_socket.sendto(data, ("192.168.1.254",1337))
    client_socket.close()
    
  
client = NTPClient()
response = client.request('europe.pool.ntp.org', version=3)
OFFSET = response.offset

bMaster = False

if (__settings__.getSetting( "Master" ) == 'true'): bMaster = True

if bMaster == True:
    GiveOrders()
    
else:
    ListenForOrders()

Just ignore the ntp stuff the problem was there before i implemented that aswell.
