This package provides a C & python library to handle WebRTC connections. Audio, video and data channel are supported.
WebRTC signaling needs to be done externally, this package provides hooks.
In the context of the entire robot software, signaling is done
in the gizmo_webrtc package.
Below is the reference of the yawl.Application python class that implementations
need to subclass:
class Application(object):
"""
Interface for client applications to override.
This handles only one peer connection at a time (for now)
"""
# do stuff - subclasses should call these
def create_pc(self, peer_id):
""" create a webrtc pipeline, a data channel, and start the call.
The offer will come on the on_pc_set_session_description
callback
"""
pass
def delete_pc(self):
pass
def datachannel_send(self, data):
""" send data down the data channel
"""
pass
def add_ice_candidate(self, sdp_index, candidate):
""" add a remote ICE candidate
"""
pass
def set_session_description(self, msg):
""" set remote peer SDP description
"""
pass
def set_ice_servers(self, servers):
self.ice_servers = servers
# when stuff happens - subclasses should override those
def on_datachannel_data(self, data):
""" called when data is available on the data channel
"""
pass
def on_disconnect(self, _):
""" called when the peer connection is closed
"""
logger.info("got 'disconnect' event, deleting the peer connection")
self.delete_pc()
def on_ice_candidate(self, msg):
""" called when a new local ICE candidate is available
"""
pass
def on_session_description(self, msg):
""" called when the SDP for an offer is ready, typically
some time after calling create_pc
"""
pass
