Gst-python fails to import on FRDM-IMX95 walnascar (Python3.13)

[ha1234]

Trying to import gst-python (`from gi.repository import Gst`) results in a RuntimeError:

Traceback (most recent call last):

Has anyone else seen this issue? Unfortunately I can't go back to scarthgap as there isn't board support for the FRDM EVK. For clarity this is using a custom image using the imx-6.12.49-2.2.0 manifest

Hi @ha1234,

Thank you for contacting NXP Support!

GStreamer’s Python bindings (gst-python / PyGObject) do not yet fully support Python 3.13.
The failure occurs inside the gi.overrides.Gst GObject Introspection layer, not in user code.

As a workaround, it is necessary to downgrade the Python version used in the system.
In embedded Linux systems built with Yocto, this can be done by rebuilding the image and explicitly selecting a supported Python version (e.g. Python 3.12) in local.conf.

This ensures compatibility with PyGObject and allows from gi.repository import Gst to work correctly at runtime.

Best Regards,
