ArvDevice is an abstract base class for the control of cameras. It provides an easy access to the camera settings, and to its genicam interface for more advanced uses.
ArvStream * arv_device_create_stream (ArvDevice *device
,ArvStreamCallback callback
,void *user_data
);
Creates a new ArvStream for video stream handling. See
ArvStreamCallback
for details regarding the callback function.
