Hi!
I am very happy that the video streaming api in olympe was fixed and mostly it works very well. However, sometimes my python script exits with a segmentation fault. I have narrowed it down to that this code can reproduce the issue:
import olympe
drone = olympe.Drone("192.168.42.1")
print("Before connection")
drone.connection()
print("Connected?", drone.connection_state())
drone.start_video_streaming()
print("Entering loop.")
while 1:
pass
Note however that the error is not consistent, but show up sometimes and sometimes not.
The line print("Connected?", drone.connection_state())
prints:
Connected? ReturnTuple(OK=True, message='The device is connected', value=None, error_code=0)
All the print(…) statements run, including the "Entering loop"
.
Do you know what the issue can be and how to solve it?
The error mesages:
Fatal Python error: Segmentation fault

Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)
My system:
Ubuntu 18.04
Python 3.6.8
Olympe 1.0.1
Pycharm community edition 2019.1.3 (But it also crashes when I run the script from the console)
Any advise would be greatly appreciated.
