gst-python-1.8.1

[Johannes Bauer]

Hello devs!

I was successfully building the new gstreamer-1.8.1 for raspbian wheezy. It works good so far.
However when I try to build gst-python i get following output:


make  all-recursive

I tried different versions of PyGObject, which does not change the outcome.
I can not find PyGObject_Type in /usr/include nor in /usr/local/include.
It seems to be defined in the pygobject sources in "gi/pyobject-external.h", but this file does not to be installed anywhere.

Do u have any ideas what could be the problem?

Kind regards

Here it is defined in /usr/include/pygobject-3.0/pygobject.h:

  #define PyGObject_Type              (*_PyGObject_API->object_type)

This is with version 3.20.1. Which one do you use?

Sebastian,

thank you very much for your answer.

I use pygobject-3.0.0 and i also have a /usr/local/include/pygobject-3.0/pygobject.h,

but it lacks the definition of PyGObject_Type.

I also tried building 3.21.0, but it requires a higher version of gobject-introspection, which fails to build on my system.

I compared the sources of pygobject-3.0.0 and 3.21.0 and it seems that they changed pygobject.h in version 3.7.91.

So i downloaded gyobject-3.8.3 and was able to compile and install gyobject and gst-python-1.8.1.

The problem is when I run my python script, stillmy older gst-python 1.2.0 version is used and not version 1.8.1.

How can i tell python to use the new gi with gst 1.8.1?

Kind regards

JB

Try setting sys.path.append('path to new version libs') from Python.

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

For some reason if you do make uninstall and clean "Too many levels of symbolic links". will still persists on gst-python. Try uninstalling gst-python and re-extract from tar file and make install.

 

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

 

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

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):

For some reason if you do make uninstall and clean "Too many levels of symbolic links". will still persists on gst-python. Try uninstalling gst-python and re-extract from tar file and make install.

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

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:

I do not believe that you can force gi to load its libraries by appending the typelib folder to your sys.path. You should use the environment variable GI_TYPELIB_PATH to point it to the correct folder (typically: /usr/lib/girepository-1.0)

[Johannes Bauer-2]

Hey guys!

Thanks for your answers!

Appending the typelib folder to sys.path did not work.

I just copied my typelibs from /usr/local/lib/girepository-1.0/

to /usr/lib/girepository-1.0/

and now it works.

I assume appending the path to GI_TYPELIB_PATH would have also done the trick.

Thank you a lot, it works now!

Cheers,

JB
