Answer 1

You can install libcrystalhd-dev package by running below command

echo "deb http://ftp.ubuntu.com/ubuntu   focal universe" >> /etc/apt/sources.list
sudo apt-get update

and then try reinstalling with the installation script.

However, if you using ARM architecture then it may not be found there.

The ffmpeg script has been updated for AMS v2.6.0 so you can use that directly.
