Thanks @1kko gist is updated ...

Thanks for this.

This script will stop at sudo su -. Instead try:

sudo sh -c "echo '/opt/intel/mediasdk/lib' > /etc/ld.so.conf.d/imsdk.conf"

Also use make -j$(getconf _NPROCESSORS_ONLN) on all your make commands to use multiple cores where possible.

Also add steps:

sudo usermod -a -G render username
sudo usermod -a -G video username
