Stream.wait() returns None

I am trying to get an image from the teledyne dalsa linea line camera. I am using TriggerMode off. When I call the stream.wait() it returns <class ‘NoneType’> instead of composite. In the GenICam browser with same settings I am able to see an image. I am using Ubuntu 21.04.05 LTS and the latest version of cvb.

stream = device.stream(stream_type=cvb.CompositeStream)
stream.start()
composite, status, node_enum = stream.wait()

I also have a 2d camera from lucid and it works fine with the same code.

Hi @sewtsbh,

Did you check the status? If the status is OK, you should get a valid composite.

I also want to know which PixelFormat you use. Currently we have an issue with the Linea Color and its BiColorRGB8 PixelFormat.
