README

        
## librtcdc is a tiny WebRTC DataChannel implementation that works everywhere (Beta).

**BEING REWRITEN**

#### Features

* Tiny <2k LOC, easy to understand/bind/extend

* Talks with each other, latest Chrome/Chromium, Firefox, Opera?, Safari?

* 'Official' Python binding

* Lack of docs

#### Prerequisites

* Python & Cython (only for Python binding)

* ICE - [libnice](http://nice.freedesktop.org/wiki/) (>= 0.1.8)

* DTLS - [OpenSSL](https://www.openssl.org/)

* SCTP - [usrsctp](https://github.com/sctplab/usrsctp)

#### Python demo

```python

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()

```
