Camera

Core class for acquiring the camera and converting its input into a Texture.

Changed in version 1.8.0: There is now 2 distinct Gstreamer implementation: one using Gi/Gst working for both Python 2+3 with Gstreamer 1.0, and one using PyGST working only for Python 2 + Gstreamer 0.10. If you have issue with GStreamer, have a look at GStreamer compatibility

class kivy.core.camera.CameraBase(**kwargs)[source]

Concrete camera classes must implement initialization and frame capturing to a buffer that can be uploaded to the gpu.
