Do you get the same error on Python cli if you do;
from gi.repository import Gst ?
Could you paste output of following command from python cli?
Import sys
Sys.path
Also check if you have Gst *.typelib available for gi.repository
Might be under;
/usr/lib64/girepository-1.0/Gst-1.0.typelib

Hello!
I recompiled gstreamer with --enable-introspection=yes, recompiled pygobject and gst-python. I have the gst-1.0.gir and other gst .gir files in /usr/local/share/gir-1.0/
Still the same error, that I already sent in the previous mail:
ERROR:root:Could not find any typelib for Gst
Traceback (most recent call last):
File "gstreamer.py", line 11, in <module>
from gi.repository import Gst as gst
ImportError: cannot import name Gst
Here is the output of gst-python configure and make install (still same error without passing overrides dir):

gi is not able to find Gst. Did you configure gstreamer with --enable-introspection=yes and do you have “.gir” files ?

Hello Shishir!
I really appreciate your input!
I uninstalled the older gstreamer and gi version and added your suggestion to my py-script and now python finds gi but cannot find Gst.
The "make check" on gst-python fails due to "Too many levels of symbolic links".
gi/overrides/__init__.py is a link to itself. That seems to be the problem here. However I dont know if it is a problem for the installation.
The "make install" puts Gst in /usr/local/lib/python2.7/site-packages/gi/overrides, whereas the rest of gi is installed to /usr/local/lib/python2.7/dist-packages/gi.
I tried copying the content fron site-packages to dist-packages, but it did not help.
Still I get the error msg:
ERROR:root:Could not find any typelib for Gst
Traceback (most recent call last):
File "gstreamer.py", line 11, in <module>
from gi.repository import Gst as gst
ImportError: cannot import name Gst
Does anyone know how to resolve that issue?
Kind regards
JB
