Just Basic Camera Stuff, but you gotta start somewhere.
Four screens showing camera orientation, aspect ratio, and image capture. On Android orientation = all is available, on the desktop change the window size to change the window from landscape to portrait to simulate rotating a mobile device.
Available on most of the usual platforms.
The example demonstrates Preview Widget layout: orientation, aspect ratio, and letterbox handling. Also switching between cameras, image capture, and screenshot capture. On Android only it demonstrates video with audio capture, pinch/spread zoom, and tap focus/exposure.
This example depends on Camera4Kivy. Read about Camera4Kivy because, depending on the platform you may need to install a camera provider.
pip3 install camera4kivy
Camera4Kivy depends on the 'master' version of Buildozer. Currently 1.2.0.dev0
pip3 install git+https://github.com/kivy/buildozer.git
The example includes a camera provider and a buildozer.spec.
