In some projects maintainers have more time than in others. In PyGObject we have right now a big lack of contributors with consequences far worse than lack of documentation. That said, your problem is with GStreamer, you should ask there.

I try to compile gstreamer 0.11.1 on Ubuntu Oneiric 11.10 with this: sudo apt-get install bison flex wget http://gstreamer.freedesktop.org/src/gstreamer/gstreamer-0.11.1.tar.gz tar -xvzf gstreamer-*.tar.gz cd gstreamer-* ./configure sudo make sudo make install All succesfully. This install the binaries under /usr/local/ But apparently, the first problem comes, I need compile gir files for create the typelib files. I see on the package gir1.2-gstreamer-0.10 for Ubuntu, that I need at least all this typelib files: /usr/lib/girepository-1.0/Gst-0.10.typelib /usr/lib/girepository-1.0/GstBase-0.10.typelib /usr/lib/girepository-1.0/GstCheck-0.10.typelib /usr/lib/girepository-1.0/GstController-0.10.typelib /usr/lib/girepository-1.0/GstNet-0.10.typelib http://packages.ubuntu.com/es/precise/gir1.2-gstreamer-0.10 http://packages.ubuntu.com/es/precise/i386/gir1.2-gstreamer-0.10/filelist So I don't know until now where get that .gir files or how to generate the gir files for 0.11. Apparently gir files is like an XML format with the migration spec. Then I should compile the files with something like for generate the typelib files: /opt/pygi/bin/g-ir-compiler --includedir=. --includedir=. /usr/share/gir-1.0/Gst-0.10.gir -o /usr/lib/girepository-1.0/Gst-0.10.typelib http://manpages.ubuntu.com/manpages/natty/man1/g-ir-compiler.1.html I don't know where find documentation for this process, just I google for known words and found things like this for extract knowledge: http://pastebin.com/jUP0aLEH The info is very spread and nobody writes a documented procedure for this. I found on http://live.gnome.org/GnomeGoals/AddGObjectIntrospectionSupportthat Gstreamer have support done for instrospection, but no reference that how to do it. So I keep google for hours and I found this, that it show me a little how to generate the .gir files with g-ir-scanner: http://wksprivate.appspot.com/pastebin/detail-js/9060/ /usr/local/bin/g-ir-scanner -v --namespace Gst --nsversion=0.10 \ 283. --add-include-path=. --add-include-path=. \ 284. --include=GObject-2.0 \ 285. --include=GModule-2.0 \ 286. --include=libxml2-2.0 \ 287. --library=gstbase-0.10 \ 288. --libtool="/bin/sh ../libtool" \ 289. --pkg gobject-2.0 \ 290. --pkg gstreamer-0.10 \ 291. --pkg gstreamer-base-0.10 \ 292. --output Gst-0.10.gir \ 293. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstbin.h \ 294. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstbuffer.h \ 295. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstbus.h \ 296. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstcaps.h \ 297. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstchildproxy.h \ 298. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstclock.h \ 299. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstcompat.h \ 300. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstconfig.h \ 301. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstdebugutils.h \ 302. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstelementfactory.h \ 303. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstelement.h \ 304. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstenumtypes.h \ 305. `pkg-config --variable=includedir gstreamer-0.10`/gst/gsterror.h \ 306. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstevent.h \ 307. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstfilter.h \ 308. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstformat.h \ 309. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstghostpad.h \ 310. `pkg-config --variable=includedir gstreamer-0.10`/gst/gst.h \ 311. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstindexfactory.h \ 312. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstindex.h \ 313. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstinfo.h \ 314. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstinterface.h \ 315. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstiterator.h \ 316. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstmacros.h \ 317. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstmarshal.h \ 318. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstmessage.h \ 319. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstminiobject.h \ 320. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstobject.h \ 321. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstpad.h \ 322. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstpadtemplate.h \ 323. `pkg-config --variable=includedir gstreamer-0.10`/gst/gstparamspecs.h \ 324. `pkg-config --variable=includedir gstreamer-0.10`/gst/

Re: [pygtk] PyObject fails with Gst on signal sync-message::element
Hi,
what version of GStreamer are you using? I think only 0.11 (future
1.0) can be used through introspection. There are other programs that
are being ported to introspection and that use GStreamer, such as
Pitivi, I would look at them for ideas.

Tomeu

Hi Pietro,
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."

[pygtk] PyObject fails with Gst on signal sync-message::element
Hi everyone,
I am migrating a old code written with GTK+ 2.X to GTK 3+ for play a .ogv
video with gstreamer.
The problem seems that the signal "sync-message::element" is never launched
(but if it is launched sync-message).
So, as result we cannot attach a Gtk.DrawingArea() inside of another window
because I dont get never the window.xid
This is the old code for GTK+ 2.x working perfectly:
import pygtk
pygtk.require('2.0')
import gtk
import pygst
pygst.require('0.10')
import gst
import os, sys
class Video:
def __init__(self):
def on_message(bus, message):
if message.type == gst.MESSAGE_EOS:
# End of Stream
player.set_state(gst.STATE_NULL)
elif message.type == gst.MESSAGE_ERROR:
player.set_state(gst.STATE_NULL)
(err, debug) = message.parse_error()
print "Error: %s" % err, debug
def on_sync_message(bus, message):
if message.structure is None:
return False
if message.structure.get_name() == "prepare-xwindow-id":
if sys.platform == "win32":
win_id = videowidget.window.handle
else:
win_id = videowidget.window.xid
assert win_id
gtk.gdk.threads_enter()
gtk.gdk.display_get_default().sync()
imagesink = message.src
imagesink.set_property("force-aspect-ratio", True)
imagesink.set_xwindow_id(win_id)
gtk.gdk.threads_leave()
win = gtk.Window()
win.set_resizable(False)
win.set_has_frame(False)
win.set_position(gtk.WIN_POS_CENTER)
fixed = gtk.Fixed()
win.add(fixed)
fixed.show()
videowidget = gtk.DrawingArea()
fixed.put(videowidget, 0, 0)
videowidget.set_size_request(640, 480)
videowidget.show()
# Setup GStreamer
player = gst.element_factory_make("playbin", "MultimediaPlayer")
bus = player.get_bus()
bus.add_signal_watch()
bus.enable_sync_message_emission()
#used to get messages that GStreamer emits
bus.connect("message", on_message)
#used for connecting video to your application
bus.connect("sync-message::element", on_sync_message)
player.set_property("uri", "file://" + "/SOME/PATH/SOMEFILE.ogv")
player.set_state(gst.STATE_PLAYING)
win.show()
def main():
gtk.gdk.threads_init()
gtk.main()
return 0
if __name__ == "__main__":
Video()
main()
And this is the new code for GTK+ 3 not working properly because xid it is
not attached creating another window:
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
from gi.repository import Gst

win.set_resizable(False)
#win.set_has_frame(False) I dont know the name of method on gtk3 so
comment this
#win.set_position(Gtk.WIN_POS_CENTER) same but with the constant
fixed = Gtk.Fixed()
win.add(fixed)
fixed.show()
videowidget = Gtk.DrawingArea()
fixed.put(videowidget, 0, 0)
videowidget.set_size_request(640, 480)
videowidget.show()
# Setup GStreamer
Gst.init_check(None)
self.player = Gst.ElementFactory.make("playbin", "MultimediaPlayer")
self.player.set_state(Gst.State.NULL)
bus = self.player.get_bus()
bus.add_signal_watch()
bus.enable_sync_message_emission()
#used to get messages that GStreamer emits

def on_message_error(self, bus, message):
