Convert MP4 file to animated WEBP file in ffmpeg CLI

In terminal.app, install ffmpeg through homebrew

brew install ffmpeg

Validate the installation:

The Windows version of OpenSSH client doesn't include a ssh-copy-id command. I don't know why. If it does one day, then this gist can be ignored.

This script is written in PowerShell as the legacy program cmd.exe is not flexible enough for the required options.
Download the file ssh-copy-id.ps1 to your Windows PC, or copy and paste its contents to a file of the same name.
Run the script passing your linux account ssh information (for example powershell .\ssh-copy-id.ps1 pi@raspberrypi.local). If you use a non-standard port add the parameter -port=nnnn. This should work with any Linux platform.
Run the command for each linux account you connect with. You will be prompted for your Linux host password. If you have more than 1 account on any machine, you must do this for each account.

If the script won't run, then run this command once
