I have installed gstreamer from source using cerbero with the help of this link (https://gstreamer.freedesktop.org/documentation/installing/building-from-source-using-cerbero.html?gi-language=c)

All the packages are installed in the cerbero subdirectory (cerbero/build/dist/linux_x86_64) and the gstreamer version is updated to 1.18. I have installed on Ubuntu 18.04 LTS.

As gstreamer version 1.14 is available with the ubuntu 18.04 distribution, to make the system pick the latest version of gstreamer, the cerbero shell needs to be activated on the terminal using the command.

$ cerbero shell

After this the terminal console is like

[cerbero-linux-x86_64] name@sample-Latitude-5400:~/cerbero/

$ gst-inspect-1.0 --version
gst-inspect-1.0 version 1.18.4
GStreamer 1.18.4 (GIT)

I want to run a python script that imports gi (Gobject introspection) to access the gstreamer library. But when I import gi.repository package, it give the segmentation fault.

GI_TYPELIB_PATH environment variable is also set.

$ echo $GI_TYPELIB_PATH
cerbero/build/dist/linux_x86_64/lib/girepository-1.0

The starting lines of code.

import gi                             # Works fine
gi.require_version('Gst', '1.0')      # Works fine
from gi.repository import Gst         # Segmentation Fault

Following is the traceback when I run the python script (python 3.6)

Fatal Python error: Segmentation fault

Can anyone suggest what could be the possible reason ?
