Kivy camera on windows shows blank screen

[Fer Romano]

When I run the code below the camera turns on but the image does not appear.
What can it be?

import datetime
from kivy.lang import Builder
from kivy.app import App

kv = """
#:import XCamera kivy_garden.xcamera.XCamera

FloatLayout:
    orientation: 'vertical'
    XCamera:
        id: xcamera
        on_picture_taken: app.picture_taken(*args)
    BoxLayout:

        Button:

            on_release: xcamera.restore_orientation()

class CameraApp(App):
    def build(self):
        return Builder.load_string(kv)

    def picture_taken(self, obj, filename):
        print('Picture taken and saved to {}'.format(filename))

if __name__ == '__main__':
    CameraApp().run()

Is there a camera connected?
Is there a camera provider installed?

[Fer Romano]

Yes, I installed kivy garden and camera.
Turns on the camera light but does not show the image

When running xcamera.exe gives the error

File "C:\PycharmProjects\pythonProject\Aula_01\xcamera.exe\__main__.py", line
  4, in <module>
  ModuleNotFoundError: No module named 'kivy_garden.xcamera.main'

But I don't know how to install the module 'kivy_garden.xcamera.main'

For example opencv-python

Since you didn't answer this - perhaps it is not installed?

Kivy Camera documentation says almost nothing about the camera provider.
Here is some documentation from a different camera https://github.com/Android-for-Python/camera4kivy#camera-provider

This question is presumably about packaging with pyinstaller.

Elliot, you around?

[Fer Romano]

The provider installed is opencv-python. Now when running xcamera.exe there is no error, but the image does not appear. Only the camera light on

Is play True?

Sorted out!! Thank you so much!! God bless you a lot
