Class Details¶

class Aravis.FakeCamera(**kwargs)¶

Bases:: GObject.Object
Abstract:: No
Structure:: Aravis.FakeCameraClass

Aravis.FakeCamera is a class that simulate a real camera, which provides methods for the implementation of Aravis.FakeDevice and Aravis.FakeStream.

arv-fake-gv-camera is a GV camera simulator based on this class.
