[python]nettimeprovider and playbin2

[riccardo cagnasso]

Hello, i have a problem in a python-gstreamer program. My script
should create a playbin2, load a video, then take the clock from the
playbin2 and use it to create a NetTimeProvider.
The code (that is ugly because it's just a test) is this

import site
import sys, os
import pygtk, gtk, gobject
import pygst
pygst.require("0.10")
import gst

class GTK_Main:

    def __init__(self):
        window = gtk.Window(gtk.WINDOW_TOPLEVEL)
        window.set_title("Audio-Player")
        window.set_default_size(300, -1)
        window.connect("destroy", gtk.main_quit, "WM destroy")
        self.movie_window=gtk.DrawingArea()
        window.add(self.movie_window)
        window.show_all()

        self.player = gst.element_factory_make("playbin2", "player")
        self.player.set_property("uri", "file:///home/phas/Downloads/bbb.ogg")

        bus = self.player.get_bus()
        bus.connect("sync-message::element",
            self.create_moviewindow_on_sync_message(self.movie_window))
        bus.add_signal_watch()
        bus.connect("message", self.on_message)

        clock = self.player.get_clock()
        self.player.use_clock(clock)
        clock_provider = gst.NetTimeProvider(clock, None, 20000)

        base_time = clock.get_time()

        self.player.set_new_stream_time(gst.CLOCK_TIME_NONE)
        self.player.set_base_time(base_time)

        self.start_stop()


    def start_stop(self):
        self.player.set_state(gst.STATE_PLAYING)
						
    def on_message(self, bus, message):
        t = message.type
        if t == gst.MESSAGE_EOS:
            self.player.set_state(gst.STATE_NULL)
        elif t == gst.MESSAGE_ERROR:
            self.player.set_state(gst.STATE_NULL)
            err, debug = message.parse_error()
            print "Error: %s" % err, debug

    def create_moviewindow_on_sync_message(self, movie_window):
        def on_sync_message(bus, message):
            if message.structure is None:
                return
            message_name = message.structure.get_name()
            if message_name == "prepare-xwindow-id":
                imagesink = message.src
                imagesink.set_property('synchronous', True)
                gtk.gdk.threads_enter()
                imagesink.set_xwindow_id(movie_window.window.xid)
                gtk.gdk.threads_leave()
        return on_sync_message

GTK_Main()
gtk.gdk.threads_init()
gtk.main()

and the problem is that when i run the script with

export GST_DEBUG=net*:5

i get this output

** Message: pygobject_register_sinkfunc is deprecated (GstObject)

and basically that nettimeprovider doesn't work
