  • L’espace de configuration de MediaSPIP

    29 novembre 2010, par

    L’espace de configuration de MediaSPIP est réservé aux administrateurs. Un lien de menu "administrer" est généralement affiché en haut de la page [1].
    Il permet de configurer finement votre site.

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • Récupération d’informations sur le site maître à l’installation d’une instance

    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

    Added a speed feature "allow_skip_recode"

    This commit added a speed feature to make the logic of calculating
    skip_recode on a block level more explicit. This also enable the
    feature to be enabled at speed 5 where the previous logic is too
    conservative, help gain back the lost speed for —rt(-5).

  • Python ThreadedTCPServer : "Name or service not known"

    11 avril 2014, par Hal

    I was developing a ThreadedTCPServer to communicate with a PHP application also residing in this same machine. This is suppose to receive requests from this PHP app and to convert some videos locally using ffmpeg.

    Here's the code :

    # -*- coding: utf-8 -*-
    import os
    import socket
    import threading
    import logging.config
    import SocketServer, time
    from queuev2 import QueueServer

    logging.basicConfig(format=&#39;[%(asctime)s.%(msecs).03d] %(message)s&#39;, datefmt=&#39;%Y-%m-%d %H:%M:%S&#39;, filename=os.path.join(os.path.dirname(os.path.realpath(__file__)), &#39;converter.log&#39;), level=logging.INFO)

    class ThreadedTCPRequestHandler(SocketServer.BaseRequestHandler):

       def handle(self):
           data = self.request.recv(1024)
           cur_thread = threading.current_thread()
           response = "{}: {}".format(cur_thread.name, data)
           videoPool.add(data)
           print "Output! %s" % data
           self.request.sendall(response)

    class ThreadedTCPServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):
       pass

    if __name__ == "__main__":

       logging.info("Initializing...")
       videoPool = QueueServer()
       HOST, PORT = "localhost", 6666

       server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler)
       ip, port = server.server_address

       # Start a thread with the server -- that thread will then start one
       # more thread for each request
       server_thread = threading.Thread(target=server.serve_forever)

       # Exit the server thread when the main thread terminates
       server_thread.daemon = True
       server_thread.start()

       print("Server loop running in thread: %s" % server_thread.name)

       # "Groundhog day" time
       while True:
           time.sleep(999)
           pass

       #server.shutdown()

    This works well in my development laptop, but on the server i'm getting the following error :

    Traceback (most recent call last):
     File "server.py", line 31, in <module>
       server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler)
     File "/usr/lib/python2.7/SocketServer.py", line 408, in __init__
       self.server_bind()
     File "/usr/lib/python2.7/SocketServer.py", line 419, in server_bind
       self.socket.bind(self.server_address)
     File "/usr/lib/python2.7/socket.py", line 224, in meth
       return getattr(self._sock,name)(*args)
    socket.gaierror: [Errno -2] Name or service not known
    </module>

    I'm guessing it has to do with the port I'm using (6666), but I've tried others and it hasn't been working. Would Unix Domain Sockets be of use here ? Can you give me an example ?
