Computer frozen after call tello.streamon()

[Gfernandes10]

Hello I'm trying to use the library in an ubuntu 20.04 environment. I tried djitellopy 2.4.0 and 2.5.0.

My problem is that whenever I call streamon() my computer freezes and I can't do anything but reboot my machine. I don't even receive the command status ok after call this method because everything is frozen. Any clue of what could be it?

Thanks!

this is what I do:

from djitellopy import Tello

tello = Tello()

try:
    tello.connect()
    try:
        tello.streamon()
    except Exception as stream_exc:
        print("Erro ao ativar/desativar o stream:", stream_exc)
except Exception as e:
    print("Erro ao conectar ao Tello:", e)
finally:
    tello.end()

Can you try this without the try/except/finally? Maybe this causes the problem instead simply the python program crashing.

If this does not help it might be because of the video decoding trying to access hardware acceleration features which causes your machine to freeze for some reason.

It still happens without the /try/except/finally.

How I can debug or learn more about this hardware acceleration features? I'm not very familiar with it.
