Problems with Gst in python program

I'm in trouble making a simple server/client socket python program. Basically, my server (RPi3) has to stream a video (with Gstreamer) to the client (Fedora 24). The problem is that in my Fedora, I can use Gstreamer importing the libs like this: ``` import gi gi.require_version('Gst', '1.0') gi.require_version('Gtk', '3.0') from gi.repository import Gst, GObject, Gtk ``` But in my Raspbian I can't, because: ``` Traceback (most recent call last): File "peerMain.py", line 12, in <module> gi.require_version('Gst', '1.0') File "/usr/lib/python2.7/dist-packages/gi/__init__.py", line 100, in require_version raise ValueError('Namespace %s not available' % namespace) ValueError: Namespace Gst not available ``` I have tried so many things, like import gst or pygst. I also tried install some packets like ``` sudo apt-get install libgstreamer1.0-dev libgstreamer1.0-0-dbg libgstreamer1.0-0 gstreamer1.0-tools gstreamer-tools gstreamer1.0-doc gstreamer1.0-x ``` but the result was ``` gstreamer1.0-tools is already the newest version. gstreamer1.0-x is already the newest version. libgstreamer1.0-0 is already the newest version. libgstreamer1.0-0 set to manually installed. Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libgstreamer1.0-dev : Depends: libglib2.0-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages. ``` and when I explore that dependence, it derives in libglib2.0-0 and libglib2.0-bin, packets that have just been in the last version: ``` pi@raspberrypi:~ $ sudo apt-get install libglib2.0-0 libglib2.0-bin Reading package lists... Done Building dependency tree Reading state information... Done libglib2.0-0 is already the newest version. libglib2.0-bin is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded. ``` I really need it, I hope someone can help me. Thanks in advance.
