Thanks for your response. Your response seems to be right, but it doesn't work on GTK3 with PyGi This line should enable the signal for the emission. bus.enable_sync_message_emission() The Gnome Bug #631901 shows that there is a problem with the signals emitted: https://bugzilla.gnome.org/show_bug.cgi?id=631901 message::eos, message::error and sync-message::element are not emitted, just "message" and "sync-message" without members. Maybe it is a problem with MiniObject support through GI. http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstMessage.html http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstMiniObject.html#GstMiniObject Using bus.connect('message', self.on_message) and def on_message(self, bus, message): print('message: {!r}'.format(message)) it show this traceback on close: Traceback (most recent call last): File "test.py", line 62, in on_message print('message: {!r}'.format(message)) TypeError: unknown type GstMessage Also I found: "gst_bus_create_watch, since GSource aren't wrapped in pygtk gst_bus_sync_signal_handler and gst_bus_async_signal_func since these functions are used by the default bus handler anyway." http://ftp.tuwien.ac.at/hci/freedesktop.org/gstreamer/gst-python/gst/gstbus.override,v
