Python test failed with gstreamer 1.24.5

ravhad934 · December 13, 2024, 10:27am

I am trying to build Gstreamer 1.24.5 with python using below command :
meson setup . ../gstreamer --buildtype release --unity off --strip --prefix=/opt/ --libdir = /opt/lib --default-library shared --wrap-mode=nofallback -Dorc-source=system -Dgpl =enabled -Drs=enabled -Dcpp_args=-std=c++20 -Dexamples=disabled -Dtests=enabled -Dgtk_doc=disabled -Dpackage-origin=https://github.com/Gstreamer/gstreamer -Dvaapi=enabled

meson version : 1.6.0
Operating system : Ubuntu 24.04

After this i ran the tests using
ninja -l $(no of cores) all

Following tests failed :

Could someone help identify the cause of this issue and suggest a solution? Any guidance or help would be greatly appreciated.

Have you tried the latest 1.24 release yet, which is 1.24.10 currently?

ravhad934 · December 13, 2024, 12:56pm

I tried with Gstreamer version 1.24.10. It didn’t helped , same tests failed for this version also.

I’m also trying to build gstreamer (1.26) with Windows 10, Python 3.12. The meson build seemed to go fine, and I can do something like

gst-launch-1.0.exe videotestsrc ! autovideosink

but when I try to use gst-python in my program. I get an error

>>> import gi
>>> gi.require_version('Gst','1.0')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\gstreamer\gst\lib\site-packages\gi\__init__.py", line 143, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace Gst not available

So i went and did

meson test -C .\builddir\ --suite gst-python

and all of the tests failed.

So I guess I got lucky with my first build. I can’t seem to replicate it.

It turns out that I need

-Dlibxml2:python=false

to get rid of

Even though I reinstalled python 3.12 with the debug options, I still got that error during the build w/o the Dlibxml2:python=false option.
