Error while sending frame: Generic error in an external library

[quanhua92]

Hi, I am trying to run the code in Quickstart. However, there is an error while running the python3 main.py. My installation is from docker approach and I also tried to download the mp4 file several times. Thank you very much. Here is the detail:

I started the docker with the following command:

docker-compose run --service-ports gpu /bin/bash

Then, I followed the command in the Quickstart

cd examples/apps/quickstart
wget https://storage.googleapis.com/scanner-data/public/sample-clip.mp4
python3 main.py

This is the error.
