 		A camera feed gives you access to a single physical camera attached to your device. When enabled, Godot will start capturing frames from the camera which can then be used. See also [CameraServer].
 		[b]Note:[/b] Many cameras will return YCbCr images which are split into two textures and need to be combined in a shader. Godot does this automatically for you if you set the environment to show the camera image in the background.
-		[b]Note:[/b] This class is currently only implemented on Linux, Android, macOS, and iOS. On other platforms no [CameraFeed]s will be available. To get a [CameraFeed] on iOS, the camera plugin from [url=https://github.com/godotengine/godot-ios-plugins]godot-ios-plugins[/url] is required.

 		The [CameraServer] keeps track of different cameras accessible in Godot. These are external cameras such as webcams or the cameras on your phone.
 		It is notably used to provide AR modules with a video feed from the camera.
