Record video & get access to data

[timschr]

I can connect to the camera (Phantom Veo410L) by camera.connect(), but in the get_single_frame.py I get

Traceback (most recent call last):
  File "get_single_frame.py", line 22, in <module>
    get_single_frame(take_number=0, frame_number=0)
  File "get_single_frame.py", line 15, in get_single_frame
    frame_index = int(camera.takes[take_number]["firstfr"]) + frame_number
  File "/home/tim/.local/lib/python3.8/site-packages/pyphantom/flex.py", line 458, in __getitem__
    raise IndexError
IndexError

since camera.takes is empty. How can I start a recording using the pyphantom framework?
I found the toggle() function in flex.py, which makes the cameras red led blink. When I now execute get_frames(), I get the error:
CameraError: Cinemag not ready
So how can I get frames from the camera?
