Actually this issue with message::eos and other messages is fixed with
Gstreamer 1.0 aka currently as Gstreamer 0.11.91-2 on Ubuntu 12.10 (note
you need previously install gstreamer1.0 packages).
You can verify this with this slightly modified code:
#!/usr/bin/python3
from gi.repository import GObject
GObject.threads_init()
import gi
try:
gi.require_version('Gst', '1.0')
except ValueError:
print 'Could not find required Gstreamer 1.0 library.'
sys.exit(1)
from gi.repository import Gst
Gst.init(None)
mainloop = GObject.MainLoop()
pipeline = Gst.Pipeline()
def on_eos(bus, msg):
print('eos: {!r}'.format(msg))
pipeline.set_state(Gst.State.NULL)
mainloop.quit()
def on_message(bus, msg):
print('message: {!r}'.format(msg))
bus = pipeline.get_bus()
bus.add_signal_watch()
bus.connect('message::eos', on_eos)
bus.connect('message', on_message)
bus = pipeline.get_bus()
bus.add_signal_watch()
bus.connect('message::eos', on_eos)
src = Gst.ElementFactory.make('videotestsrc', None)
src.set_property('num-buffers', 10)
sink = Gst.ElementFactory.make('fakesink', None)
pipeline.add(src)
pipeline.add(sink)
src.link(sink)
pipeline.set_state(Gst.State.PLAYING)
mainloop.run()

Title:
Lack of GstMiniObject means Gst.Message is broken, can't get EOS
