Error in video_effect.py

[bhuvaneswarignanasekar]

Your code is great and most things work great but I tried video_effect.py and ran into some issues. It says log data is corrupted and then a timeout error. Would you help me to resolve it?.

@hanyazou @bhuvaneswarignanasekar, I get exactly the same issue and errors

[samlaf]

Experiencing the same issue on Ubuntu 20.04 with python3.

[Walt-H]

Check out the "Files changed" in my pull request here: #90

There's a bit you guys have to change to get it working.

I did my modifications on the keyboard_and_video.py example instead though.

[Walt-H]

To be more specific, check out the README from the fork here:
https://github.com/hanyazou/TelloPy/blob/112fec56854a3ac3ede813b3d99de20e4e0bc95f/README.md

Follow the instructions in the keyboard_and_video section, and use the modified keyboard_and_video.py.

[samlaf]

I think I found a solution for this.
You just need to add a call to wait_for_connection:

drone.connect()
drone.wait_for_connection(10.0)
drone.start_video()

Alternatively, you can add the call to wait_for_connection directly inside connect, as I did in this pull request.
