SpinnakerCamera GetNextImage() timeout

[Roger]

Hi,

I have a problem with a Spinnaker camera (Blackfly S BFS-U3-31S4M) throwing a "Failed waiting for EventData on NEW_BUFFER_DATA event. [-1011]" error due to timing out when the shot duration is longer than about 5 seconds:

This appears to be due to GetNextImage() using a hardcoded 5000 ms timeout in labscript_devices/SpinnakerCamera/blacs_workers.py. Simply increasing the timeout avoids this issue but I'm wondering if there's a configuration setting I overlooked.

I'm also not sure if others have experienced this issue, especially since Teledyne/FLIR seems to change how cameras handle settings between generations and/or in the Spinnaker SDK.

If a fix is warranted, I think eliminating the timeout altogether may be the easiest solution and relying on stop_acquisition_timeout to throw an error if any triggers are missed.
