Upgrade camera to support libcamerasrc

Author: michele-comitiniCreated Jun 3, 2026Updated Jun 5, 2026

Software Versions

Python: 3.13+
OS: PiOS Debian trixie 6.18.33+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.18.33-1+rpt1 (2026-06-01) aarch64 GNU/Linux
Kivy: 2.3.1+
Kivy installation method: any

Describe the bug RPi camera is not working anymore. Camera() class with different providers (opencv, gi) is not working. CameraGi() __init__() has a video_src parameter, but it is impossible to pass any parameters by using the standard kivy.uix Camera() class

Expected behavior Ability to read video frames from camera

rpicam-hello works.

To Reproduce

bash

$ python kivy-examples/camera/main.py

Code and Logs and screenshots workaround by shadowing the kivy.core.camera.Camera definition.

python

# test_camera.py
from  camera_providers.camera_libcamera_gi import CameraLibcameraGi as CoreCamera

# Now import the rest of kivy
from kivy.app import App
import kivy.uix.camera
kivy.uix.camera.CoreCamera = CoreCamera


class CamApp(App):
    def build(self):
        return kivy.uix.camera.Camera(index=0, resolution=(640, 480), play=True)

CamApp().run()

python

# camera_providers/camera_libcamera_gi.py
from kivy.core.camera.camera_gi import CameraGi


class CameraLibcameraGi(CameraGi):
    def __init__(self, **kwargs):
        kwargs["video_src"] = "libcamerasrc"
        super().__init__(**kwargs)
