For me, the error comes in the following line of code:

    container = av.open(drone.get_video_stream())

[hanyazou]

If it does not receive video data at all, it might be caused of some firewall. Could you try it w/o firewall?

[zweberre]

I'm receiving the same error in both keyboard_and_video.py and video_effect.py.

However, everything else seems to be working including receiving and saving images.

[PhilsLab]

Same for me, no firewall, direct connection -> video recv: timeout Maybe something has changed in the protocol? The app seems to work fine.

[PhilsLab]

Seems like "streamon" via the "SDK" always results in an ERROR response, is this maybe an issue with a new firmware?

[hanyazou]

I updated my Tello with newest firmware 01.04.78.1. It can stream video data without any errors.

[hanyazou]

I modified tello.py to re-send video start command when video receiving returns timeout error. f68360e2c870d5e092a88665ce0b68b25cdc57bc Please re-open this issue if you still have the problem.

Hi, I am trying to get the video from tello, and I am still getting this error ( Error: video recv: timeout)
