Python make_sub_socket Examples

Example #1

File: camera.py Project: abdelq/duckietown-slimremote

 def __init__(self, queue, host):
     Thread.__init__(self)
     context = zmq.Context.instance()
     self.queue = queue
     self.sock = make_sub_socket(for_images=True,
                                 context_=context,
                                 target=host)

Example #2

File: camera.py Project: duckietown/duckietown-slimremote

    def __init__(self, frame, event_img, event_ready, host, silent=False):
        super(ThreadedSubCamera, self).__init__()
        self.silent = silent
        self.frame = frame
        self.event_img = event_img
        self.event_ready = event_ready

        context = zmq.Context()
        self.sock = make_sub_socket(for_images=True, context_=context, target=host)
