Prerequisites
Python demo
import pyrtcdc
from pyrtcdc import PeerConnection
# called when the channel received a message
def on_message(channel, datatype, data):
print 'received data from channel %s: %s' %(channel.label, data)
channel.send(pyrtcdc.DATATYPE_STRING, 'Roger')
# called when a channel is created by the remote peer
def on_channel(peer, channel):
print 'channel %s created' %(channel.label)
channel.on_message = on_message
# called when a new local candidate is found
def on_candidate(peer, candidate):
print 'local candidate sdp:\n%s' %(candidate)
# called when connected to remote peer
def on_connect(peer):
peer.create_data_channel('demo', on_open=on_open)
# called when channel is opened
def on_open(channel):
channel.on_message = on_message
channel.send(pyrtcdc.DATATYPE_STRING, 'Hi')
peer = PeerConnection(on_channel, on_candidate, stun_server='stun.services.mozilla.com')
# generate local offer sdp and start candidates gathering
offer = peer.generate_offer()
# offer/answer/candidates signalling here (or somewhere)
# ...
# running until the sun cools
peer.loop()
