"""
This file reads a list of Parler video IDs and generates "multithumbnails" (a sequence of 9 evenly-spaced thumbnails).
The multithumbnails are stored in the multithumbnails/linear and multithumbnails/rect directories.
linear/ puts the thumbnails side-by-side in a linear sequence.
rect/ puts the thumbnails in a 3x3 rectangle.
To run, download this script from GitHub then:
git clone https://github.com/kylemcdonald/python-utils.git utils
sudo apt install python3 python3-pip
pip3 install --user --upgrade pip
pip3 install --user numpy ffmpeg-python opencv-python pillow

How to view a video on Parler

Let's say you have a video ID, like wfy02V209EwU taken from this map

The link for the video kiBnNejo0JW0 is at https://video.parler.com/ki/Bn/kiBnNejo0JW0. Notice that the link is: https://video.parler.com/ followed by the first two characters of the video ID, then /, then the next two characters, another /, and the video ID.

But if you click on this, you will get an error.

This is because the Parler video servers are still running (as of January 12) but the Domain Name System (DNS) is not running.
