Issue while running example streaming file. concurrent.futures._base.InvalidStateError

[aliwaqas333]

It was working fine previously and i tested recording some videos as well. But strangely now i am facing this error on line line 748 pdraw.py. I feel like i need to reset something here. Kindly help. :+1:

after running this file, streaming.py

if __name__ == "__main__":
    streaming_example = StreamingExample()
    # Start the video stream
    streaming_example.start()
    streaming_example.stop()

i get the following error.

I am using ubuntu 20.04 and my environment is working fine. I am still able to run other files such as photo.py. I am trying to stream but don't know how to make it work.

Please any help in this regard will be highly appreciated. thanks

solved now. Just add some delay after start stream to actually record.

Can you please explain more how you fixed this issue if you can provide the code you used to add the delay, that would be awesome

Have you been able to reproduce this issue lately with the latest 7.X releases ? (currently the 7.4.2?)
